Drag and drop the equation to correctly complete the sentence.

Klio2033 [76]

Answer:

y= 2x - 11

Step-by-step explanation:

(-7 +1 )/ (2-5) = 2

y= 2x +b

-1 = 2* 5 + b

solve for b and you get -11 so the equation of the line is :

y = 2x -11

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.

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

The school band has 115 members. They are raising money for band camp. If each member raises $75, what is the total amount of mo

Kaylis [27]

Answer:

a. $8625

Step-by-step explanation:

So there are 115 members and they each raise $75.

That means one member would raise $75, the second member would raise another $75, the third would raise another $75 etc....

So you just have to multiply 115 and 75 together and that gives you $8625
