Answer:

f(h(-1)) = -2.5

Step-by-step explanation:

We are given:

f(x) = (x - 3)/4

h(x) = 3x - 4

Knowing this, first find h(-1).

h(-1) = 3(-1) - 4

Multiply 3 and -1.

h(-1) = -3 - 4

Subtract 4 from -3.

h(-1) = -7

Now knowing this evaluate the function out.

f(h(-1)) = f(-7)

Evaluate f(-7).

f(x) = (x - 3)/4

Substitute variable.

f(-7) = ((-7) - 3)/4

Subtract 3 from -7.

f(-7) = (-10)/4

Divide -10 by 4.

f(-7) = -2.5

This means that f(h(-1)) = -2.5.

The price of a video game was reduced from $60 to $45. By what percentage was the price of the video game reduced?* O 15% O 25%

Naya [18.7K]

Answer:

Step-by-step explanation:

The new price, $45, can be expressed as a percentage of $60 by taking it as a fraction of $60, converting to a decimal value, and multiplying by 100%. $45/$60=3/4=0.75, 0.75x100%=75%. So since 100%-75%=25%, the value was reduced by 25%.

Reposting becuase it want let me edit my last one and somebody spam answered it.

Answer:

5Step-by-step explanation:

If you use the distance formula you can solve it pretty easily. The distance formula is:

d = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2} \\$

The two points you want are A and D. A is (-1, -4) and D is (3, -1). Plug that into the formula...

d = $\sqrt{(3 - (-1))^2 + (-1 - (-4))^2}$

d = $\sqrt{4^2 + 3^2}$

d = $\sqrt{16 + 9}$

d = $\sqrt{25}$

I can solve it in a different way if you want me to.
