Find the value of x so that the function has the given value .q(x)= 1/2x-3;q(x)=-4

Answers

Answer 1
Final answer:

To find the value of x when q(x) = -4, we set up the equation and solve for x.

Explanation:

To find the value of x for which the function q(x) is equal to -4, we can set up the equation q(x) = -4 and solve for x.

Given q(x) = 1/2x - 3, we can substitute -4 for q(x) and solve:

-4 = 1/2x - 3

Adding 3 to both sides, we get:

-1 = 1/2x

Multiplying both sides by 2 to isolate x, we have:

-2 = x

Therefore, the value of x that makes the function q(x) equal to -4 is x = -2.

Answers

The answer to this equation is 11

solve the equation, justify each step with an algebraic property
-3x=15

Answers

Final answer:

To solve the equation -3x = 15, you divide by -3 to get x = -5. To check, substitute -5 for x in the original equation to verify that the left and right sides are equal.

Explanation:

To solve the equation -3x = 15, we want to isolate x on one side of the equation. The algebraic property we will use here is the Division Property of Equality, which states that if we divide both sides of an equation by the same nonzero number, the two sides remain equal.

Step-by-Step Solution:

Start with the equation: -3x = 15.Divide both sides of the equation by -3 to isolate x: x = 15 / (-3).Simplify the right side of the equation: x = -5. We've used the Division Property of Equality and simplified the arithmetic.

Now, let's check the answer to verify it's reasonable. Substitute x = -5 back into the original equation (-3x = 15) and see if the equation holds true:

-3(-5) = 1515 = 15, which is true. So the solution x = -5 is correct.

How can I use the properties of integer exponents to simplify algebraic abd numeric expressions?

Answers

Final answer:

The properties of integer exponents like multiplication (adding exponents), division (subtracting exponents), raising a power to another power (multiplying exponents), and fractional powers (representing roots) are used to simplify algebraic and numeric expressions.

Explanation:

To simplify algebraic and numeric expressions using the properties of integer exponents, you can apply several different rules. The first step is often to write out the expression in an extended format, like how 34 can be written as 3·3·3·3. When we deal with multiplication of exponentials, we multiply the digit terms and add the exponents of the exponential terms. For example, (23)(24) equals 23+4 which simplifies to 27. When we encounter division of exponentials, we divide the digit terms and subtract the smaller exponent from the larger exponent. For instance, 57 divided by 53 would give us 57-3 which is 54.

For powers raised to another power, like (53)4, you multiply the exponents (3×4) to get 512. Remember to be cautious with examples and ensure clarity in the operations when combining exponents. Lastly, fractional powers, such as 51/2, can be interpreted as square roots. The general rule here is that xa/b represents the b-th root of x, raised to the power of a.

we know because of the sum of the interior angles of a triangle being 180, and that 5 + 6 =180

Answer:  The correct options are (1) (D) 94°  and (2) (D) 15.81.

Step-by-step explanation:  The calculations are as follows:

(1) In the attached figure, given that m∠2 = 42° and m∠3 = 52°.

We are to find the measure of ∠6.

In a triangle, the sum of the measures of two remote interior angles is equal to the measure of the exterior angle.

In the given triangle,  ∠2 and ∠3 are remote interior angles and ∠6 is the exterior angle.

So, we have

[tex]m\angle 6=m\angle 2+m\angle 3=42^\circ+52^\circ=94^\circ.[/tex]

Thus, (D) 94° is the correct option.

(2) Given that the areas of two similar hexagons are related to each other as 5 : 2 and one side of the first hexagon is 25.

We are to find the corresponding side in the other hexagon.

Let, 'a' and 'b' be the lengths of the corresponding sides of the two similar hexagons.

The, the ratios of the area of the hexagons will be a² : b².

So, we have

[tex]\dfrac{a^2}{b^2}=\dfrac{5}{2}\\\\\\\Rightarrow \dfrac{25^2}{b^2}=\dfrac{5}{2}\\\\\\\Rightarrow b^2=2\times\dfrac{625}{5}\\\\\\\Rightarrow b^2=250\\\\\Rightarrow b=5\sqrt{10}=15.81.[/tex]

Thus, the correct option is (D) 15.81.

Because a triangles angles add up to 180 degrees, we can say that 

x+4+3x+9+31=180 degrees.

The question is now a simple algebraic expression.

4x+44=180
Subtract 44 on both sides

4x=136
Divide by 4 on both sides

x= 34

m∠S= x+4, (34)+4, 38
m∠S=38 degrees

m∠T= 3x+9, 3(34)+9, 102+9, 111
m∠T=111 degrees

I hope this helps and please mark brainiest answer :D

Final answer:

The value of x is 34°, resulting in the measures of angles S and T being 38° and 111° respectively, in triangle RST.

Explanation:

The sum of the angles in a triangle is always 180 degrees. Given that angle R is 31°, we can set up an equation with the other two angles expressed in terms of x. This equation is:

31° + (x + 4)° + (3x + 9)° = 180°

Combining like terms yields:
4x + 44° = 180°
Subtracting 44 from both sides gives:
4x = 136°
Dividing both sides by 4 gives the value of x:
x = 34°

Now, we can find the measures of the other two angles:

​m°S = x + 4 = 34° + 4° = 38°
​m°T = 3x + 9 = 3(34°) + 9° = 102° + 9° = 111°

Therefore, the value of x is 34°, angle S measures 38°, and angle T measures 111°.

You are shipping a care package to your sister in college. It costs $0.85 per pound plus a flat-fee of $12 to ship the package. Write and use an algebraic expression to find the total cost of shipping a 7 pound care package.

Answers

The expression should be
.85x+12=c. (C=cost, x=package in lbs)
And it would cost $17.95
.85(7)+12=
5.95+12=17.95

To find the total cost of shipping a 7-pound care package, you can use the formula: Total Cost = (Cost per pound * Number of pounds) + Flat fee. When applying this formula to the given scenario, the total cost to ship a 7-pound care package is $17.95.

To find the total cost of shipping a 7-pound care package, consider that it costs $0.85 per pound plus a flat fee of $12. You can create an algebraic expression to find the total cost:

Total Cost = (Cost per pound * Number of pounds) + Flat fee

Substitute in the values: Total Cost = ($0.85 * 7) + $12 = $5.95 + $12 = $17.95

What do you add to 31/4 to make 8

Answers

31/4

This can be changed into 7 3/4.

To get the whole number 8, you only need to add 1/4.
7 3/4 + 1/4 = 7 4/4 = 8

The answer is 1/4.

Final answer:

To find what needs to be added to 31/4 to make it equal to 8, you subtract 31/4 from 8. This results in 0.25, which is the number to be added to 31/4 to obtain 8.

Explanation:

To solve this question, we first need to understand the problem. We wish to find a number which, when added to 31/4, equals 8. By subtracting 31/4 from both sides of the equation, we can find the missing number.

So, the equation becomes 8 - (31/4) = missing number.

The computation follows: missing number = 8 - (31/4) = 8 - 7.75 = 0.25

Therefore, if you add 0.25 to 31/4, you will get 8. This illustrates the principle of basic equation solving in mathematics.

The constant rate of change for the relationship shown in the table is $8 per hour. find the missing values

Answers

y=8x
This will give you your answer.
Final answer:

The constant rate of change of $8 per hour signifies that for each hour that passes, the associated value increases by $8. To find missing values in the table, you add or subtract $8 per hour depending on whether you're looking forward or backward in time.

Explanation:

Since the constant rate of change in your table is $8 per hour, this means that for each hour that passes, the value in your relationship increases by $8. This value is akin to the concept of constant slope in the graph of a linear function, where the 'rise over run' (or change in y-values over change in x-values) remains the same.

To find the missing values in your table, start with the first known value and add $8 for each subsequent hour. If you're moving backwards (i.e., from a time later to an earlier time), you would subtract $8 for each hour.

For example, if you know that the value at 2 hours is $20, then the value at 3 hours would be $20 + $8 = $28. On the other hand, the value at 1 hour would be $20 - $8 = $12.

By applying this step-by-step process, you should be able to fill in the missing values in your table.

There are many types of fractions like Proper fractions, Improper fractions, Like fractions, Unlike fractions, Mixed fractions and so on.

Fractions are of the form [tex]\frac{a}{b}[/tex] where the number on the top 'a' is called the numerator and the number on the bottom 'b' is called the denominator.

For example take a fraction, 3/10.

Here 3 is the numerator and 10 is the denominator.

For fractions of type 3 [tex]\frac{1}{10}[/tex], it is called mixed fraction.

Here 3 is a whole number part and 1/10 is the fractional part.

We can convert first mixed fraction into improper fraction where the numerator is found by multiplying 3 to 10 and then adding 1 and the denominator equals the denominator of the fractional part.

3 [tex]\frac{1}{10}[/tex] = (3 × 10 + 1) / 10 = [tex]\frac{31}{10}[/tex]
