1. horizontal shrink by factor of 2/3 means multiply outside the f(x) or outside the x^2 by 2/3:
(2/3)•f(x)
2. translation left 5 units means "x+5" inside:
(2/3) • f(x+5)
3. tranlate down 2 units means "-2" outside:
(2/3) • f(x+5) -2
or (2/3) (x+5)^2 - 2

they are asking what is angle S .. that looks like it's the same one as angle P on the other triangle so ...
S= 59°
Answer:
y = 4x
Step-by-step explanation:
If y is directly proportional to x (which is what I assume you are meaning in this question), this means that
y = kx, where k is the constant of proportionality.
To find k, we simply substitute in the given x and y values, and solve for k. i.e we to get:
8 = k x 2.
k = 8/2 = 4.
so y = 4x
