Multiply the numerators together and the denominators to get the ending fraction.
Ex: 3/4 x 3/4 = 9/16, and simplify if needed.
Answer:
y = -3/2x + 6
Step-by-step explanation:
Parallel lines have the same slope so slope is -3/2
Using (4,0)
y = mx + b
0 = -3/2(4) + b
0 = -6 + b
b = 6
so y = -3/2x + 6

Answer:
21 kWh
Step-by-step explanation:
1. Subtract 25% from the original amount.
25% of 28 kWh is ...
0.25 × 28 kWh = 7.00 kWh
Subtracting this from 28 kWh, we find the usage after reduction to be ...
28 kWh - 7 kWh = 21 kWh
__
2. We know that if we reduce 100% of a quantity by 25%, then the resulting amount is (100 -25)% = 75% of the original. As a fraction, this is 75/100 = 3/4 of the original amount. Then the reduced usage is ...
(3/4) × (28 kWh) = 3·(7·4)/4 kWh = 3·7 kWh = 21 kWh
__
Mario must reduce his usage to 21 kWh or less.
