Step-by-step explanation:

Step 1: Define

A = -3n + 2

B = 5n - 7

A - B

Step 2: Simplify

Substitute: -3n + 2 - (5n - 7)
Distribute negative: -3n + 2 - 5n + 7
Combine like terms (n): -8n + 2 + 7
Combine like terms (Z): -8n + 9

What’s all input for f(x)=3

defon

Answer:

all inputs are equal to 3

Step-by-step explanation:

$f(x) = 3 \\ = 3 \times 1\\ = 3 \times {x}^{0} \\ anything \: raised \: to \: 0 \: is \: 1 \\$

$\\ substituting \: any \: value \\ \: of \: x \: in \: f(x) \\ f(3) = 3 \times {3}^{0} \\ = 3 \times 1 \\ = 3 \\$

$\\ similarly \: all \: values \: of \: x \: will \\ give \: 3$

2) f(x) = x² ** g(x)= 3x – 2 Find f(g(-4)

Usimov [2.4K]

Answer:

$f(g( - 4)) = 196$

Step-by-step explanation:

The functions are;

$f(x) = {x}^{2}$

and

$g(x) = 3x - 2$

We want to find

$f(g( - 4))$

First we find g(-4) to get:

$g( - 4) = 3 \times - 4 - 2$

$g( - 4) = - 12- 2$

$g( - 4) = - 14$

Now

$f(g( - 4)) = f( - 14)$

This implies that,

$f(g( - 4)) = {( - 14)}^{2}$

$f(g( - 4)) = {( - 14)} \times - 14$

$f(g( - 4)) = 196$

What is the solution to the equation P over 9 equals 90

Zepler [3.9K]

P/9 = 90

Multiply 9 to 90 to isolate the variable.

P = 9 x 90

P = 810
