Answer:

<B=24

Step-by-step explanation:

<B=x

<A=5(x+7.2)

x+5(x+7.2)=180

x+5x+36=180

6x=180-36

6x=144

x=24

Answer and Step-by-step explanation:

When two angles are supplementary, the add up to 180 degrees.

Measure of angle A is 5 times the sum of the measure of angle B + 7.2.

So, we have b, and we have a.

a + b = 180

a = 5(b + 7.2)

b = ?

We input 5(b + 7.2) for a into the equation.

5(b + 7.2) + b = 180

Now we distribute the 5 and combine like terms.

5b + 36 + b = 180

6b + 36 = 180

Subtract 36 from both sides, then divide both sides by 6 to get b.

6b = 144

b = 24

<u>The measure of angle B is 24 degrees.</u>

please help! functions and relations. f(x)= square root of x-4. find the inverse of f(x) and it’s domain.

likoan [24]

ANSWER:

$\:D.\text{ }f^{-1}\left(x\right)=\left(x+4\right)^2;x\ge-4$

STEP-BY-STEP EXPLANATION:

We have the following equation:

$f(x)=\sqrt{x}-4$

The inverse is the following (we calculate it by replacing f(x) by x and x by f(x)):

$\begin{gathered} x=\sqrt{f^{-1}(x)}-4 \\ \\ \sqrt{f^{-1}(x)}=x+4 \\ \\ f^{-1}(x)=(x+4)^2 \end{gathered}$

The domain would be the range of the original equation, and it would be the range of values that f(x) could take, which was from -4 to positive infinity, that is, f(x) ≥ -4.

Therefore, the domain is x ≥ -4.

So the correct answer is D.

$\:f^{-1}\left(x\right)=\left(x+4\right)^2;x\ge -4$

2. Sam has two part-time jobs, delivering pizza and mowing lawns. He makes $9/hr delivering pizza and $7/hr mowing lawns. Last w

frutty [35]

Answer:

<h2>22 hours and 10 hours </h2>

Step-by-step explanation:

let the jobs be x and y, so that

x+y=32--------1

9x+7y=248----2

x=32-y

substitute x=32-y for x in equation 2 we have

9(32-y)+7y=248

open bracket we have

288-9y+7y=248

-2y=248-288

-2y=-40

2y=40

divide both sides by 2 we have

y=40/2

y= 10 hours

subtitute y=10 for y in equation 1 to find x

x+10=32--------1

x=32-10

x=22

x=22 hours
