The equation of a straight line is given by:

y = mx + c

where m is the slope and c is the y-intercept.

From the given graph, the y-intercept is 1.

The slope of a straight line is given by:

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

Where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are two points on the line.

From the graph, (0, 1) and (14, 8) are two points on the line, thus:

[tex]m= \frac{8-1}{14-0} = \frac{7}{14} = \frac{1}{2} [/tex]

Therefore, the equation representing the graph is [tex]y= \frac{1}{2} x+1[/tex]

The answer to this is a: y=1/2 x+1

A hole was dug 2 3/8 feet deep for a fence post. The fence post is 6 feet long. How far above the ground will the fence post be when it is placed in the hole? Enter your answer as a mixed number, in simplified form, in the box.

PLEASE ANSWER ASAP

Answers

[tex]\text{Answer: The fence post will be }3\frac{5}{8}\ feet\text{ far above the ground when it is placed in the hole.}[/tex]

Explanation:

Since we have given that

Length of hole dug for a fence post is given by

[tex]2\frac{3}{8}\ feet=\frac{19}{8}\ feet[/tex]

Length of the fence post = 6 feet

we need to find the length of the fence post above the ground is seen when it is placed in the hole.

So, Length of the fence post above the ground is given by

[tex]6-\frac{19}{8}\\\\=\frac{48-19}{8}\\\\=\frac{29}{8}\\\\=3\frac{5}{8}\ feet[/tex]

[tex]\text{Hence, the fence post will be }3\frac{5}{8}\ feet\text{ far above the ground when it is placed in the hole.}[/tex]

The table shows the number of balls, by sport, in the gym.
A. The ratio of soccer balls to all balls is 4:25
B. For every 10 balls in the gym, 3 are basketballs
C. None of the above

Answers

A. The ratio of soccer balls to all balls are 4:25

All the balls combined are 50 balls

8 of the balls are soccer balls so that makes the ration 8:50

In the simplest form it is 4:25 since you can't divide 4 or 8 by 50, you can use 2
and you get 4:25 as your answer
So it is A.

The ratio of soccer balls to all balls is 4:25.

Given that;

The table shows the number of balls, by sport, in the gym.

Now, We have;

Number of soccer balls = 8

And, Total number of balls = 50

Hence, The ratio of soccer balls to all balls is,

⇒ 8 : 50

⇒ 4 : 25

Thus, We get;

The ratio of soccer balls to all balls is 4:25.

To reduce 32 grams of a 25% antiseptic solution to a 10% solution, how much distilled water should a pharmacist add?

Answers

Hello,

8 grams is 10% of (8g)/0.10=80 grams
80 grams-32 grams=48 grams
ANSWER: You should add 48 grams of water to 32 grams of 25% solution to make a 10% solution.

Answer:

48 grams

Step-by-step explanation:

= 32 + 25 because 32 grams and 25 %

= 57 - 10 because there's 10%

= 47 + 1 because 10 ÷ 10 = 1

Find the value of x and AB if B is between A and C, AB = 2x, AC = 6x - 5 , BC = 7

Answers

We have AB + BC = AC.

2x + 7 = 6x - 5

2x - 6x = - 5 - 7

-4x = -12

x = -12/-4

x = 3

We both know that x is 3.

We also want AB.

AB = 2x

AB = 2(3)

AB = 6

Did you follow?

Final answer:

The problem deals with the segment addition postulate. By setting up and solving the relevant equation (2x + 7 = 6x - 5), we find that x = 3. Therefore, the length of AB = 6.

Explanation:

The subject of this question is segment addition postulate in mathematics. Given that B is between A and C, it implies that AB + BC = AC. From the problem, it's given that AB = 2x, AC = 6x - 5 and BC = 7. Setting up the equation would yield 2x + 7 = 6x - 5. Solving this equation gives us x = 3. Therefore, by substituting x=3 in AB = 2x we find that AB = 6.

To find x:
Triangles are in total 180 degrees. The two triangles are basically 1 triangle split in half. If the triangle share the same side, has similar angles (shown by the curves on both sides at the top(Angle BAC and CAB), and has similar sides(shown by the hashes made in the lines AC & AB), you can conclude 'x' as a 90 degree angle.
To find y:
The measurment of the angle DCA is 47 degrees. For x, we concluded the answer to be 90 degrees, making the other side of the line 90 degrees as well.Since a triangle is 180 degrees, we can add 47 and 90 to get 137. Taking that answer, we subtract it from the value of 180 degrees to get 43 degrees. So y equals 43.

Expand and simplify [tex] (3x-2)^{2} [/tex]

Answers

You can just 1) multiply the binomial by itself, or you can use 2) the square of a binomial pattern. I'll show it to you both ways.

1) Multiply the binomial by itself.

(3x - 2)^2 = (3x - 2)(3x - 2) =

Multiply every term of the first binomial by every term of the second binomial, then collect like terms. (This is often called using FOIL.)

= 9x^2 - 6x - 6x + 4

= 9x^2 - 12x + 4

2) Use the square of a binomial pattern

The square of a binomial is

(a - b)^2 = a^2 - 2ab - b^2

a^2 is the square of the first term.
b^2 is the square of the second term.
-2ab is the product of the two terms and 2.

You have

(3x - 2)^2,
where the first term is 3x, and the second term is -2

square the first term: 9x^2
square the last term: 4
the product of the terms and 2 is: -12x

Put it all together, and you get

9x^2 - 12x + 4

just like we got above with the other method.

Answers

200-20+40

The 16 isn’t in the equation because they are coming back.

So your answer is 220.

Hey You! Let's break this down step by step:

You have 200 people in a race, and 20 drop out. Meaning, you must subtract:

200 - 20 = 180

Next, 16 take a break, so you must subtract again:

180 - 16 = 164

Finally, 40 people are added back, so, you must add:

164 + 40 = 204

Explanation:

To subtract the numbers given, we need to add all the positive numbers and then subtract the sum of the negative numbers.

Positive numbers: [tex]$6 + 4 + 6 + 4 + 5 + 5 + 6 = 36$[/tex]

Negative numbers: [tex]$-6 - 6 - 4 - 1 - 4 = -21$[/tex]

In a video game, Val scored 30% fewer points than Peeta. Peeta scored 1060 points. How many points did Val score?

1060 x .30= 318
1060-318=742
Val scored 742 points

Val (huh, I didn't know that was an actual name) scored around 742 points, 30% fewer than Peeta. Since, 30% of 1060 can be found by multiplying 30% as a decimal (0.30), which means that 30% of 1060 is 318. However, it doesn't say that Val scored 30% of the points Peeta scored. No, it says that Val scored 30% LESS than the score Peeta scored. So, we're subtracting.

1060 - 318 = 742

So, Val scored 742 points.

Find the measure of angle KLM.

This is an EXPLAIN YOUR THOUGHTS question which means you need to:

1) include the properties, theorems, etc. that you used to set up an equation.

2) Show the euqation you used to solve for x and thus solve for the angle measure of KLM

Answers

Answer: 64 degrees

-------------------------------------
-------------------------------------

We'll use these properties:

Property 1: Linear pairs of angles are adjacent (touching) and supplementary. They form a straight angle. By definition they are supplementary meaning they add to 180 degrees.

Property 2: For any triangle, the three angles always add to 180 degrees

-------------------------------------

We need the measure of angle KLJ in terms of x.

Notice how KLJ and KLM form the straight angle JLM (which is 180 degrees). So we'll use property 1 mentioned above. Let's isolate angle KLJ to get...

(angle KLM) + (angle KLJ) = 180
(20x+4) + (angle KLJ) = 180 ... use the substitution property to replace angle KLM with its algebraic expression
angle KLJ = 180 - (20x+4)
angle KLJ = 180 - 20x-4
angle KLJ = -20x + 176

-------------------------------------

Now that we know angle KLJ, we can use this angle along with the angles JKL and KJL. Basically we're focusing on the smaller triangle on the left (the obtuse triangle)

Add those three angles up and set the result equal to 180 degrees. I'm using property 2 now.

(angle KLJ) + (angle KJL) + (angle JKL) = 180
(-20x+176) + (6x+4) + (8x+18) = 180

Therefore the equation we need to solve is: (-20x+176) + (6x+4) + (8x+18) = 180

Let's do so...
(-20x+176) + (6x+4) + (8x+18) = 180
-20x+176 + 6x+4 + 8x+18 = 180
(-20x+6x+8x)+(176+4+18) = 180
-6x+198 = 180
-6x+198-198 = 180-198
-6x = -18
-6x/(-6) = -18/(-6)
x = 3

After solving for x, we get x = 3
Let's use this to find the measure of angle KLM

angle KLM = 20*x+4
angle KLM = 20*3+4
angle KLM = 60+4
angle KLM = 64

The measure of angle KLM is 64⁰

What are supplementary angles?

Supplementary angles are two angles whose measures add up to 180⁰ In other words, when placed adjacent to each other, they form a straight line.

From the figure

Given

<J = (6x+4)⁰

<K = (8x + 18)⁰

<KLN = 180 -(20x +4) (supplementary angles)

In Triangle KLN

<J + <K + <L = 180⁰(sum of angles in triangle)

Substitute

(6x + 4) + (8x + 18) = (20x + 4)(sum of 2 int.<s is equal to exterior<)

Simplifying

6x + 8x - 20x = 4 - 4 - 18

14x -20x = -18

-6x = -18

x = -18/-6

= 3

Substitute into (20x + 4) to find the measure of angle KLM

20x +4 = 20(3) + 4

= 60 + 4

= 64⁰

The measure of angle KLM is 64⁰
