4 3/4 = 19/4
133/(19/4) = 133(4/19) = 1197/19 = 63 mph
Answer:
y=-x+4
Step-by-step explanation:
3-5/1-(-1) = -1
(y-(-1)) = -1(x-5)
y+1 = -x+5
y= -x +5-1
y= -x + 4
Hi!
Switch up the variables:
y = -14x - 2.
x = -14y - 2.
Add 2 to both sides.
x + 2 = -14y - 2 + 2.
x + 2 = -14y.
Divide by -14 on both sides.
(x + 2) / -14 = -14y / -14.
(x + 2) / -14 = y.
Change the y to f^-1(x).
f^-1(x) = (x + 2) / -14.
Hopefully, this helps! =)
