I take it we aren't solving for x.
So
2x + 28 + 9 - 5
2x + 28 + 4
2x + 32.
First we need to use two point to find the slope (m)
m=(y2-y1)/(x2-x1)
X1=-8
Y1=-4
X2=6
Y2=10
m=(10-(-4))/(6-(-8))
m=(10+4)/(6+8)
m=14/14
m=1
Eq of the line formula :
Y-y1=m(x-x1)
Y-(-4)=1(x-(-8))
Y+4=x+8
Y=x+4
320 students. Because you have to divide 384 by 6 which will give you 64 which is the number for the students that chose art and then subtract that from the total students which are 384 and you'll get 320 as your answer for the student that didn't pick art.
So your equation is a composite function. It means to plug 1.5 as x into g(x), then the answer you get for that, plug into h(x).
So.
g(1.5)=8-3(1.5)
=8-4.5
=3.5
Then.
H(3.5)=2x+5
=2(3.5)+5
=7+5=12
Your final answer is 12.
7 + 4 + f^2 - 5f + 2 = 13 + 3^2 - 5(3) = 13 + 9 + 15 = 28 + 9 = 37
