Answer:

Step-by-step explanation:

g(3)=3^2-4

g(3)=9-4

g(3)=5

f(x)=f(5)

f(5)=3(5)-2

f(5)=15-2

f(5)=13

Hello from MrBillDoesMath!

Answer: 13

Discussion:

Evaluate f(g(3)).

g(3) = 3^2 -4 = 5 so

f(g(3)) = f(5) = 3*5-2 = 15 -2 = 13

Thank you,

MrB

Choose the quadratic equation that has a leading coefficient of 8 and solutions -10 and 7/8

Maru [420]

Answer:

$f(x)=8x^2+73x-70$

Step-by-step explanation:

We are given

zeros as -10 and 7/8

now, we can set up function as

$f(x)=a(x-(-10))(x-\frac{7}{8})$

now, we are given that

leading coefficient is 8

so, a=8

now, we can plug it

$f(x)=8(x-(-10))(x-\frac{7}{8})$

now, we can simplify it

$f(x)=8\left(x^2+\frac{73x}{8}-\frac{35}{4}\right)$

so, we get

$f(x)=8x^2+73x-70$

The length of a rectangle is 88 inches longer than the width. If the perimeter of the rectangle is 7272 inches, find the measur

tresset_1 [31]

The perimeter (IP) of a rectangle is

P = 2(length + width)

let width = w then length = w + 88

P = 2(w+w+88) = 2(2w+88) = 4w+176

Thus P = 4w+176 = 7272

hence 4w = 7272 - 176 = 7096

so w = 7096/4 = 1774

width = 1774 inches and length = w+88 = 1774+88 = 1862 inches

Which ordered pair is a solution to the system of linear equations?

Andreyy89

We have to add the equations in a clever way such that one of the variables cancels out. If you multiply the top one with 3 and the bottom one with 2, you cancel x. Like this:

3(2x+3y)=3*6 => 6x + 9y = 18
2(-3x+5y)=2*10 => -6x + 10y = 20

9y + 10y = 38 => 19y = 38 => y=2

If y=2 then 2x + 6 = 6 => x=0

The pair (0,2) is a solution.
