Answer:
<em>t</em>=2d/s
Step-by-step explanation:
Combining Expressions and isolating the variable <em>t</em>
12 hours worth $87
1 hour would be $87/12 = $7.25
9 hours worth $65.25
1 hour would be $65.25/9 = $7.25
The constant of proportionality is $7.25 per hour.
Answer:
C
Step-by-step explanation:
y=mx+n m is slope if slopes are perpendicular m1.m2=-1
(2/3) . (-3/2) = -1
m1=2/3
m2=-3/2
y=(2/3)x-3 m=2/3 n= -3
y=(-3/2)x+2 m = -3/2 n = 2
te answer is 5.5 because -21/-6 is 3.5 and 9-3.5 is 5.5
hope i helped
