Answer:
A
Step-by-step explanation:
This is because when you do a the answer states, multipliying the top by 2, makes the top equation 6x-6y=12. When you subtract the second from the first you get:
6x - 6y = 12
- 6x + (-)9y = (-)3
Which results in -15y = 9.
This results in an eliminated variable from the start of the system of equation.
Answer:
<h2>cos90° = 0°, tan0° = 0°,</h2><h2>cos(-90°) = 0°, cot270° = 0°</h2>
Step-by-step explanation:

A) $675
b) $202.50
Multiply $13.50 by the total number hours worked each week during each season
The answer is A.
Speed = distance / time
Speed = (4*400) / (6*60) (6*60 to turn minutes to seconds)
Speed = 1600 / 360
Speed = 4.44
Velocity = displacement / time
since she is running in a circle, she stops where she started making he displacement 0
Velocity = 0 / 6*60
Velocity = 0
