F(x) = 8 - 10x
g(x) = 5x + 4
Finding (fg)(-2).
First let us find fg(x), this is the same as f(g(x))
f(g(x))
f(5x + 4)
Recall, f(x) = 8 - 10x, therefore f(5x + 4) would be such that anywhere we see x in the f(x), we replace it with 5x + 4
f(x) = 8 - 10x
f(5x +4) = 8 - 10(5x + 4)
= 8 - 50x - 40
= -50x + 8 - 40
= -50x - 32
f(g(x)) = fg(x) = -50x - 32
fg(-2) = -50*(-2) - 32 = 100 - 32 = 68
Therefore fg(-2) = 68
I hope this helped.
The answer is five 5 hope it helps you out :)
Answer:
y = -x + 8
Step-by-step explanation:
The equation can be written as;
y = mx + b
where b is the y-intercept
From the diagram , b= 8
y = mx + 8
To get m, substitute (8,0 ) into the equation
0 = 8x + 8
x = -8/8
x = -1
So the full equation is;
y = -x + 8
Answer:
5^-2
Step-by-step explanation:
All you have to do in this situation is subtract the powers :)
10-12=-2
The answer is B) 108 cubic inches because since prism H is three times the height of prism G's height , the volume of prism H is three times prism G volume therefore you multiply prism G's height; 36 by 3 to get 108
