Answer:
y+2= -1/5(x+1)
Step-by-step explanation:
if lines are perpendicular their slopes are negative reciprocal
y=mx+b where m is the slope
y=5x-10 has the slope 5 so a perpendicular line will have slope -1/5
equation point slope form
(y-y1) = m(x-x1) where m is slope, and (x1,y1) any point that belongs to the line
y+2= -1/5(x+1)

Answer:
The predicted value of x = 2
Step-by-step explanation:
y = 4.2x - 3 is the given equation.
Now, y = 5.4
Putting in the above equation, we get
5.4 = 4.2x - 3
or, 5.4 + 3 = 4.2x
or, 8.4 = 4.2 x
⇒ x = 8.4/4.2
⇒ x = 2
Answer:
f(g(x))= x-2
Step-by-step explanation:
f(g(x))= (x-4)+2 -plug g(x) into the place of x in the f(x) function
f(g(x))= x-4+2 -parentheses aren't needed
f(g(x))=x-2 -combine like terms
16 million divided by four years is $4 million per year
