To find the rate of speed per hour, you need to divide the kilometer (90) by the hours (4).
90/4=
22.5
Answer:
Step-by-step explanation:
a.
y=0.75x
y-y1=(y2-y1)/(x2-x1)×(x-x1)
y-3=(6-3)/(8-4) (x-4)
y-3=3/4(x-4)
y-3=3/4 x-3
y=3/4 x-3+3
y=3/4 x
if y=f(x)
f(x)=0.75x
c.
f(12)=0.75×12=9$
X = 2 + 4y....with x being the larger number and y being the smaller number
OR
y = 2 + 4x....with y being the larger number and x being the smaller number
