<span>Given that f(x) = 2x + 5 and g(x) = x − 7
</span>f(g(x)) = 2(x − 7) + 5
f(g(x)) = 2x - 14 + 5
f(g(x)) = 2x - 9
when x = −3 , f(g(-3)) = 2(-3) - 9 = - 6 - 9 = -15
Answer
<span>A. −15</span>
Answer:
f(x) = 2(x+3)^4
Step-by-step explanation:
vertical stretch is always outside parenthesis and left and right shift is always inside parenthesis with left being adding the number while right being subtracting the number.
The required simplified value of B - A = -6.
<h3>What is simplification?</h3>
The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.
Since, line Ax + By = 3 and x + 3y = -5 are parallel than slope of both the line will be same,
m = -1/3 = -A/B
From above
A = B/3 - - - - -(1)
Now line Ax + By = 3 passed through the point (-7, 2). So,
-7A + 2B = 3
from equation 1
-7B/3 + 2B = 3
-B/3 = 3
B = -9
Now put B in equation 1
A = -9 / 3
A = -3
Here,
B - A = -9 + 3 = -6
Thus, the required simplified value of B - A = -6.

Answer:
D. $350
Step-by-step explanation:
Replace 'x' with 60. g(60)= 5(60) =+ 50
g(60)= 300 + 50
g(60) = 350.
Answer:
AC = 28 feet
Step-by-step explanation:
Point C is the midpoint of AB, so AC is half the length of AB:
AB/2 = (56 ft)/2 = 28 ft = AC
