We are given the following:

3(x+1)+4(x+1)=49

Simplify the left side of the equation by using the distributive property. After you distribute, you end up with:

3x+3+4x+4=49

Combine like terms:

7x + 7 = 49

Subtract 7 from both sides to cancel the +7 on the left. When you do that, you end up with:

7x = 42

Divide both sides by 7 to isolate x.

\frac{7x}{7} =\frac{42}{7}

Your final answer should be:

x=6

Which represents the inverse of the function f(x) = 4x?
nekit [7.7K]

Answer:

\displaystyle h(x) = \frac{1}{4}x

Step-by-step explanation:

Sinse in this case you are dealing with direct variation, all you are doing is taking the <em>multiplicative</em><em> </em><em>inverse</em><em> </em>of 4, which is ¼:

\displaystyle f(x) = 4x \rightarrow f^{-1}(x) = \frac{1}{4}x

This option is not an answer choise. Perhaps there was a typographical errour.

I am joyous to assist you at any time.

Morgan is reupholstering an old chair with two circular cushions. Each cushion has a circumference of 7. 85 feet. He will need t
kramer

The total fabric Morgan needs to cover the cushions will be 19.64 square feet.

It is given that each cushion has a circumference of 7.85 feet.

It is known that the circumference of a circle = 2πr, where 'r' is the radius of the circle.

2πr = 7.85

r = 1.25

<h3>What is an area of a circle?</h3>

area of a circle is πr².

now, we can calculate the area = π× 1.25² = 4.91 square feet

since each circular cushion has two circular faces so the total number of faces Morgan needs to cover will be 4.

Therefore, the total fabric needed= 4×4.91 = 19.64 square feet.

to get more about the area of a circle, refer to the link:
