Answer:C
Step-by-step explanation:
y=12x is almost the same as y=12x+3 but +3 moves the line 3 up making it parrallel
8.5 hours
T = 9 • h (hours worked)
$76.50 = 9 • h
76.50/9 = h
h = 8.5 hours
15 percent of 24
(15/100) * 24
3.6
Answer:
-8
Step-by-step explanation:
5(x+12)= 20
5x+60= 20
5x= -40
x= -8
First, find the gradient/slope:
Use slope formula:
m=(y2-y1)/(x2-x1)
=(11-5)/(3-1)
=6/2
=3
Then use the line equation formula:
y=mx+c
You can substitute (1,5) if you like, also must substitute the slope as well!
5=3x1+c
c=2
Then find the full equation, which gives you the answer:
y=3x+2
