Answer:
Step-by-step explanation:
to find the inverse, just switch x and y
so if u have these points : (-3,9) , (-2,4), (0,0), (1,1)
the inverse would be : (9,-3) , (4,-2), (0,0), (1,1)
B) f(g(x)) = 15x² + 18
Plug the entire equation of g(x) in for the x in f(x)
f(g(x)) = 5(3x² + 3) + 3
f(g(x)) = 15x² + 15 + 3
f(g(x)) = 15x² + 18
-1/3 slope will make another perpendicular line
Answer: 6.4 miles/hour
Speed = distance/time
19.2/3 = 6.4
Hope this helps!
y-2=1/3(x+3)
m=(y2-y1)/(x2-x1)
m=(4-2)/(3-(-3))
m=2/(3+3)
m=2/6
simplify
m=1/3
y-y1=m(x-x1)
y-2=1/3(x-(-3))
x=-1 or 5 or 2
x³-6x²+3x+10=0
(x+1)(x-5)(x-2)=0
x+1=0 ⇒ x=-1
x-5=0 ⇒x=5
x-2=0 ⇒ x=2
