Answer:

y=1/2x+5

Step-by-step explanation:

y=mx+b

The equation of the line that passes through the point (6,8) and has a slope of 1/2 will be y=1/2x+10.

A straight line is a combination of endless points joined on both sides of the point. A linear equation has the form y = mx + b in the slope-intercept format. X and Y are the variables in the equation. The values m and b represent the line's slope (m) and the value of y when x is 0.

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that the equation of the line that passes through the point (6,8) and has a slope of 1/2,

The standard equation of the line passes through the points (x₁,y₁) having slope m is,

y-y₁=m(x-x₁)

Substitute the given value as

y-8=-1/2(x-6)

2(y-8)=-1(x-6)

2y-16=x-6

2y=x-6+16

2y=x+10

y=1/2x+10

Thus, the equation of the line that passes through the point (6,8) and has a slope of 1/2 will be y=1/2x+10.

Answer:

BC ≈ 11.9 cm

Step-by-step explanation:

Using the sine ratio in the right triangle

sin58° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{BC}{14}[/tex]

Multiply both sides by 14

14 × sin58° = BC, thus

BC ≈ 11.9 cm ( to 1 dec. place )

To find the length of side BC in a triangle, you would typically use the Pythagorean theorem if given a right triangle. Additional information or a diagram is required for a precise answer. The theorem can be rearranged to solve for any side of the triangle.

Finding the length of side BC requires you to use the principles of geometry, specifically the Pythagorean theorem if this is a right triangle context. However, without a provided diagram or additional information, it's impossible to give a specific answer. The Pythagorean theorem states that in a right-angle triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This can be written as a^2 + b^2 = c^2, where c represents the length of the hypotenuse, and a and b represent the lengths of the other two sides. You could rearrange this equation to solve for b if you knew the lengths of a and c.

The evaluation that shows the reasons the focus must be the point (0, 4) are as follows;

The location of the vertex of the parabola at the point (0, 2), and the location of the directrix on the x-axis, we get;

The location of the focus is on the line passing through the vertex, which is the line x = 0

Answer:

y = -3x + 6

Step-by-step explanation:

Distribute -

y + 6 = -3x + 12

Subtract 6 from both sides, final answer

y = -3x + 6

Final answer:

The equation y + 6 = -3(x - 4) in slope-intercept form is y = -3x + 6, where the slope is -3 and the y-intercept is 6.

Explanation:

To write the equation y + 6 = -3(x - 4) in slope-intercept form, which is y = mx + b, we need to solve the equation for y. First, distribute the -3 to both terms within the parentheses: y + 6 = -3x + 12. Next, subtract 6 from both sides to isolate y: y = -3x + (12 - 6). Simplifying the equation, we get y = -3x + 6. Thus, the slope-intercept form of the equation is y = -3x + 6, where the slope (m) is -3 and the y-intercept (b) is 6.

Answer

Step-by-step explanation:

From the attached diagram below,

< ADC + <D = 180° (sum of linear angle) ------------(1)

<B + <C + <D = 180° (sum of interior angle in a triangle)---------(2)

Since the two equations are equal to 180°, We equate the two equation

i.e

(1) = (2)

< ADC + <D = <B + <C + <D

<D from the left hand side will cancel <D on the right hand side

We are now left with

<ADC = <B + <C

The Exterior Angle Theorem is proven by using the Triangle Sum Theorem, the Linear Pair Postulate, and the Subtraction Property of Equality to show that the sum of the interior opposite angles of a triangle equals the exterior angle.

To complete the proof of the Exterior Angle Theorem using the fact that angle ACD is an exterior angle of triangle BCD and prove that angle B + angle C = angle ACD, follow the steps below:

Answer:

∠A= 112.5°, ∠B=67.5°, ∠C is 67.5° and ∠D 112.5°.

Step-by-step explanation:

Consider the provided information.

The sum of all interior angle of a polygon is: [tex](n-2)180[/tex]

Substitute n = 8.

[tex](8-2)180=1080[/tex]

Thus, the measure of each angle is: [tex]\frac{1080}{8}=135[/tex]

∠B and ∠C are congruent and their sum is 135°

∠B+∠C=135°

∠B=67.5°

Hence, the m angle B and m angle C is 67.5°.

The sum of all angles of a quadrilateral is 360°.

∠A+∠D+∠B+∠C=360°

∠A+∠D=360°-135°

∠A+∠D=225°

∠A and ∠D are congruent and their sum is 225°

∠A+∠D=225°

∠A=∠D=112.5°

Hence, the m angle A and m angle D is 112.5°.

Answer:

Step-by-step explanation:

The domain on all x-squared parabolas is all real numbers.  

The range of an x-squared parabola is always found at the y coordinate of its vertex, and then is determined by whether it opens upwards or downwards. Our vertex has a y coordinate of -1 and opens downwards, so the range is all real numbers less than or equal to -1.

There are no x-intercepts (aka places on the graph that go through the x-axis), but the y-intercept is also the vertex, which is (0, -1).

Because this is an upside down parabola, it has a max point, again at the vertex.  It has no min point.

It increases from negative infinity to its max point and is notated as follows: (-∞, 0]

and decreases from its max point to negative infinity: [0, -∞)

Answer:

There are 7 chairs in each row length.

Step-by-step explanation:

Let number of chairs in 1 row be 'x'.

Let total number of chairs be 'y'.

Given:

Hue can form 6 rows of a given length with 3 chairs left over.

It means that Total number of chairs is equal to chairs in 1 rows multiplied by number of rows which is 6 plus number of chairs which is left which is 3.

Framing in equation form we get.

[tex]y=6x+3 \ \ \ \ \ equation \ 1[/tex]

Also Given:

Hue can form 8 rows of that same length if she gets 11 more chairs.

It means that Total number of chairs is equal to chairs in 1 rows multiplied by number of rows which is 8 minus number of chairs which is required more which is 11.

Framing in equation form we get.

[tex]y=8x-11 \ \ \ \ \ equation \ 2[/tex]

From equation 1 and equation 2 we can say that L.H.S is same.

So according to law of transitivity we get;

[tex]6x+3=8x-11[/tex]

Combining like terms we get;

[tex]8x-6x=11+3[/tex]

Using Subtraction and Addition property we get;

[tex]2x=14[/tex]

Now Using Division Property we will divide both side by 2.

[tex]\frac{2x}{2}=\frac{14}{2}\\\\x=7[/tex]

Hence there are 7 chairs in each row length.

By setting up the equations as described, we find that each row has 7 chairs.

The subject of the question is a mathematical problem involving the concept of solving linear equations. Let's denote the number of chairs in a row as x. According to the problem, Hue can form 6 rows with 3 chairs leftover. So the total number of chairs she has is 6x + 3. Also, if she gets 11 more chairs, she can form 8 rows of the same length. So, in that case, the total number of chairs would be 8x. So we can write the equation 6x + 3 + 11 = 8x.

This equation simplifies to 14 = 2x. Therefore, x = 7. That is, each row has 7 chairs.

Given that [tex]a_{1}=6[/tex] and [tex]a_{n}=a_{n-1}+3[/tex]

Given sequence is of the form arithmetic sequence

For arithmetic sequence the sequence is [tex]a_{1},a_{2},a_{3},...[/tex]

The nth term is of the form  [tex]a_{n}=a_{n-1}+d[/tex]

Here  [tex]a_{1}=6[/tex] and [tex]a_{n}=a_{n-1}+3[/tex]

from this the common differnce is 3.

Therefore d=3

To find  [tex]a_{2}[/tex], [tex]a_{3}[/tex] , [tex]a_{4}[/tex]

[tex]a_{n}=a_{n-1}+d[/tex]

put n=2 and d=3 we get

[tex]a_{2}=a_{1}+3[/tex]

[tex]a_{2}=6+3[/tex]   (here  [tex]a_{1}=6[/tex] )

Therefore [tex]a_{2}=9[/tex]

[tex]a_{n}=a_{n-1}+d[/tex]

put n=3 and d=3 we get

Options A, B, and D each have exactly one solution. Option C has no solution because it simplifies to a contradiction.

To determine which of the given equations have exactly one solution, we will analyze each equation to see if it can be simplified or rearranged to form an identity (true for all values of [tex]\( x \))[/tex] or a contradiction (false for all values of [tex]\( x \))[/tex], or if it remains a valid equation with a unique solution for [tex]\( x \).[/tex]

An equation has exactly one solution if it can be simplified to the form [tex]\( ax = b \)[/tex] where [tex]\( a \)[/tex] and [tex]\( b \)[/tex] are constants, and [tex]\( a \)[/tex] is not zero.

Let's analyze each option step by step:

Option A: [tex]\( -5x + 12 = -12x - 12 \)[/tex]

1. Add [tex]\( 12x \)[/tex] to both sides: [tex]\( -5x + 12x + 12 = -12 + 12x \).[/tex]

2. This simplifies to [tex]\( 7x + 12 = -12 \).[/tex]

3. Subtract [tex]\( 12 \)[/tex] from both sides: [tex]\( 7x = -24 \).[/tex]

4. Divide by

  This equation has exactly one solution, [tex]\( x = -\frac{24}{7} \).[/tex]

Option B: [tex]\( -5x + 12 = 5x + 12 \)[/tex]

1. Add [tex]\( 5x \)[/tex] to both sides: [tex]\( -5x + 5x + 12 = 5x + 5x + 12 \).[/tex]

2. This simplifies to [tex]\( 12 = 10x + 12 \).[/tex]

3. Subtract \( 12 \) from both sides: [tex]\( 0 = 10x \).[/tex]

4. Divide by [tex]\( 10 \)[/tex]: [tex]\( x = 0 \).[/tex]

  This equation has exactly one solution, [tex]\( x = 0 \).[/tex]

Option C: [tex]\( -5x + 12 = -5x - 12 \)[/tex]

1. Subtract \( -5x \) from both sides: [tex]\( 12 = -12 \).[/tex]

  This simplifies to a contradiction since [tex]\( 12 \)[/tex] does not equal [tex]\( -12 \).[/tex]

  Therefore, this equation has no solution.

Option D: [tex]\( -5x + 12 = 5x - 5 \)[/tex]

1. Add \( 5x \) to both sides: [tex]\( -5x + 5x + 12 = 5x + 5x - 5 \)[/tex].

2. This simplifies to [tex]\( 12 = 10x - 5 \)[/tex].

3. Add [tex]\( 5 \)[/tex] to both sides: [tex]\( 17 = 10x \).[/tex]

4. Divide by [tex]\( 10 \)[/tex]: [tex]\( x = \frac{17}{10} \)[/tex].

  This equation has exactly one solution, [tex]\( x = \frac{17}{10} \)[/tex].

Based on this analysis, Options A, B, and D each have exactly one solution. Option C has no solution because it simplifies to a contradiction.

Step-by-step explanation:

I just know for a fact. These are the correct answers.

The situation that can be represented by the inequality x < 3 is that the backpack is heavier than 3 kg.

The situation that can be represented by the inequality x < 3 is: The backpack is heavier than 3 kg.

This means that if the weight of the backpack is represented by 'x', then 'x' is less than 3 kg.

For example, if the weight of the backpack is 2 kg, then 2 is less than 3, which satisfies the inequality x < 3.

The situation that can be represented by the inequality x<3 is "The ceiling is lower than 3 m." This inequality shows that the value of x is less than 3. In real-world terms, it could mean the height of a ceiling, length of an object, or the age of a child, among other things. However, in the given options, it corresponds to a ceiling's height being less than 3 meters.

Let's explore a couple of examples to understand inequalities better with metric measurements:

Answer:

The larger angle is 52. 4

The smaller angle is 37. 6

Step-by-step explanation:

The equation is:

(x-14. 8)+x=90

x+x-14. 8=90

2x=90+14. 8

2x=104. 8

x=52. 4

The value for the larger angle is x

and x =52. 4

The value for the smaller angle is x-14. 8

and x-14. 8=52.4-14.8

=37.6

Verification

(x-14.8)+ x=90

(52.4-14.8)+52.4=90

37.6+52.4=90

90=90

The smaller angle measures 37.6° and its complementary angle measures 52.4°. These measures satisfy the condition that one angle is 14.8° less than the measure of its complementary angle, and both angles sum to 90°.

To determine the measure of each angle when one angle is 14.8° less than its complementary angle, we need to set up an equation.

Complementary angles add up to 90°.

Let's denote the smaller angle as x, so the complementary angle is x + 14.8°. The equation becomes:

x + (x + 14.8°) = 90°

Combining like terms, we have:

2x + 14.8° = 90°

Subtracting 14.8° from both sides:

2x = 90° - 14.8°

2x = 75.2°

Dividing both sides by 2 to solve for x:

x = 75.2° / 2

x = 37.6°

So the smaller angle measures 37.6° and the complementary angle measures x + 14.8° = 37.6° + 14.8° = 52.4°.

Hello, thanks for usin Brainly. :)

Let's solve by using distributive property.

8(2x-6)=96

16x-6=96

16x-48=96

     +48 +48

16x = 144

x = 9

First, what we did was do 8 x 2 & 6 x 8.

Then, we got 16x-6=96.

We want to get X by itself, therefore we need to get rid of -48, so we 48 to all of our terms.

Then our equation should look like 16x = 144.

Divide and get 9!

Therefore, x = 9.

Wait, how can we be sure?

Let's check our answer.

Let's allow our x value to be 9.

Now, our equation should look like:

8(2(9)-6=96

Follow the PEMDAS rule.

8(18-6)=96

8(12)=96

8 times 12 is 96.

96 = 96 Done!

Therefore, we know our answer is correct.

The solution for x in that equation is 3.

The solution to the equation 1/2 - x + 3/2 = x - 4 is x = 3. This solution was found by simplifying and solving the equation step-by-step.

You're trying to solve an equation for x. The equation given is 1/2 - x + 3/2 = x - 4.

First, combine similar terms on each side of the equation. So, this becomes -x + 2 = x - 4.

Next, add x to both sides to get 2 = 2x - 4.

Then, add 4 to both sides to isolate x on one side, you will get 2x = 6.

Finally, divide both sides by 2 to determine the value of x. So, x = 3.

Explanation:

The question asks how many miles you would drive to and from work in 3 days if your round-trip to work is 4310 miles. To calculate this, you just need to multiply the daily round-trip distance by the number of days you travel. In this case, you travel to and from work for 3 days.

Determine the daily round-trip distance. (Already provided as 4310 miles)

Multiply the daily round-trip distance by the number of days traveled: 4310 miles × 3 days.

The calculation would be 4310 miles × 3 which equals 12,930 miles. This is the total distance driven to and from work over the 3 day period.
