Answer:
19 - 28/n
n= 7
19 - 28/7
19-4
= 15
Step-by-step explanation:
The value of m(n(x)) is x = 9 is 70
<h3>Composite function</h3>
This is a<em> function embedded into another function.</em>
<em />
Given the following functions:
- m(x) = 2x - 2
- n(x) = 4x (Assumption)
The composite function m(n(x)) will be expressed as:
m(n(x)) = m(4x)
m(4x) = 2(4x) - 2
m(4x) = 8x - 2
Is x = 9, then;
m(n(9)) = 8(9) - 2
m(n(9)) = 70
Hence the value of m(n(x)) is x = 9 is 70

Answer:
y = -2x + 7 and y = x - 2
Step-by-step explanation:
2x + y = 7
y = -2x +7
x - y = 2
-y = -x +2
y = x - 2
