Answer: 10 + 7x
40
We can use exclusion method:
A and C is not correct because Ms Hernandez doesn't want to spend more than 40 dollars --> so it must be less than or equal to 40
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.
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:
=
±
= - 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!
It would still be 0 because anything times 0 is still 0.
