Answer:
130 gallons initally, losing approx. 1.33333 gallons per minute, will be empty in approx 97.5 min
Step-by-step explanation:
1: y-intercept = (0, 130)
2: take two points (0, 130) & (30, 80)
use slope equation (80 - 130)/ (30 - 0) = -40/30 = -4/3
3: line equation is y=-4/3x+130
make y=0
0=-4/3x+130
-130=-4/3x
-130/-4/3=x
97.5=x
Answer:
you need to do math. it is very easy
The slop is 8/5
Slop is just rude over run so from one point to the next it’s 8 points up and 5 points over
Follow PEMDAS:
First, distribute 3 to all terms within the parenthesis
3(4x) = 12x
3(5) = 15
12x + 15 + 2
Simplify. Combine like terms
12x + (15 + 2)
12x + 17
12x + 17 is your answer
hope this helps
