X is 120 degrees, you ask to find the value of y, but there is no y
x-5= 0
move -5 to the other side
sign changes from -5 to +5
x-5+5= 0+5
x= 5
x-6= 0
x-6+6= 0+6
x= 6
Answer: B. 5 and 6
Answer:
y=-2x+8
Step-by-step explanation:
slope formula is y=mx+b
slope(m)=-2, and y-value(b)=8
so ya just plug in what ya know to get y=-2x+8
<u>Given </u>that the functions
and 
We need to determine the value of the function 
First, we shall determine the composition of the function 
<u>Function </u>
<u>:</u>
Let us determine the function 
Thus, we have;
![(g \circ f)(x)=g[f(x)]](https://tex.z-dn.net/?f=%28g%20%5Ccirc%20f%29%28x%29%3Dg%5Bf%28x%29%5D)
![=g[x+4]](https://tex.z-dn.net/?f=%3Dg%5Bx%2B4%5D)



Thus, the function is 
<u>Value of the function </u>
<u>:</u>
The value of the function can be determined by substituting x = -3 in the function 
Thus, we have;

Simplifying the terms, we get;



Thus, the value of the function
is 1.
