the correct answer is 124
Answer:
y = -1
Step-by-step explanation:
1/2 of 4y + (y + 3) = 0
1/2 X 4y + (y + 3) = 0
4y/2 + (y + 3) = 2y + y + 3 = 0
3y = -3
∴ y = -1
The y intercept of
is
The above equation can be rewritten as
Answer 108
Step-by-step explanation:
So first you would subtract 14 from 36. 36-14=12, then you would multiple by 9. 9 times 12 = 108.
Elevators starts 90 feet below ground level after 15s it is 20 feet below ground level. So the distance it has gone up is 70 feet because 90-20=70. Use this common equation: speed =distance/time and put your values in to get the correct answer. Time is 15s. You can eliminate c and d before you even start as the elevator is moving upwards. For the questions below just use a calculator.
