Answer please!!!!!!!!!!!!!!!!!!
castortr0y [4]
The rule is "whatever the input is, multiply it by 5, then subtract 2"

For example, if the input is 4 then 4*5 = 20 and 20-2 = 18
So in short, the input 4 leads to the output 18 as shown in the top row of the diagram. 

The answer is the box on the bottom row, right hand side where it says "x 5"  and "-2" in the two bubbles.

Can someone explain this pls
Ludmilka [50]

Answer:

Step-by-step explanation:

( g ° f )(x) = ( x + 7 )² = x² + 14x + 49

20 + 3(x² + 14x + 49) = - 34

20 + 3x² + 42x + 147 = - 34

3x² + 42x + 201 = 0 ⇔ x² + 14x + 67 = 0

D = 196 - 268 = - 72 < 0

There is no any roots in set of real numbers.

The values of x in set of complex numbers are:

x_{12} = \frac{- 14 }{2} ± \frac{6\sqrt{2}i }{2}

x_{12}  = - 7 ± 3√2 i

Answer:

87.35%

Explanation:

If the total is 1,032,471, it equals 100%

African Americans are in 901,896

1,032,471=100

901,896 = X

Cross multiply

1,032,471x=90,189,600

Divide

x= 87.35%

Hope you get it!
