Answer:
Step-by-step explanation:
Slope-intercept form means the equation of a line should be in this form:

So we re-write our equation into this form like this:

Answer:
48
Step-by-step explanation:
80 divided by 4 is 20 so thats 1/4 of 80
80-20=60
1/5 of 60 = 12
20+12=32
80-32=48
Answer:
P1 = P2 - ma*t
Step-by-step explanation:
ma= P2-P1/t
we multiply by t both sides of the equation
ma*t = (P2 - P1)*t/t
ma*t = P2 - P1
we sum by P1 both sides of the equation:
P1 +ma*t = P2 - P1 +P1
We ave:
P1 + ma*t = P2
we subtract by ma*t both sides of the equation:
P1 + ma*t -ma*t = P2 - ma*t
finally we have:
P1 = P2 - ma*t
