6x2, because using pemdas, 2x2= 4 then 4x3=12. The answer must equal 12, and 6x2 does.
y= -1/5x-4
explanation:
the rise over run is -1/5
the y-intercept is -4
The value of the composite function f(g(x)) is 2x^2 + 15
<h3>How to evaluate the composite function f(g(x))?</h3>
The functions are given as:
f(x) = 2x + 1
g(x) = x^2 + 7
We have the function f(x) to be
f(x) = 2x + 1
Substitute g(x) for x in the equation f(x) = 2x + 1
So, we have
f(g(x)) = 2g(x) + 1
Substitute g(x) = x^2 + 7 in the equation f(g(x)) = 2x + 1
f(g(x)) = 2(x^2 + 7) + 1
Open the brackets
f(g(x)) = 2x^2 + 14 + 1
Evaluate the sum
f(g(x)) = 2x^2 + 15
Hence, the value of the composite function f(g(x)) is 2x^2 + 15

MARK BRAINLIEST PLEASE ☺️☺️
First you multiply 20 by .15 and you get 3. Subtract 3 by 20 and you get 17. Now multiply $17 by 30 and you get 510. She spent $510 on 30 calculators
