Answer: 20 mph
Step-by-step explanation:
Given
The airplane is at a height of 528 ft with a rate of 20 mph
The automobile is also directing east at the rate of 40 mph
at this instant, they are separating by the relative velocity between them

Answer:
They have the same y-intercept
Step-by-step explanation:
I got it right
3t=4s+5 (s=side of square, t= side of triangle)
s=t-3, t=s+3, using this value for t in the first equation gives us:
3(s+3)=4s+5
3s+9=4s+5
-s=-4
s=4
so the side length of the square is 4cm and the area of a square is just s^2
A=16cm^2
7 1/2 is already simplified to its lowest terms
Answer:
B)
Step-by-step explanation:
For the function
, all coordinates this line passes through should make this inequality true.

This corresponds with table B.
