Answer:

The answer is s = 1.

Step-by-step explanation:

Opposite sides of a parallelogram are equal so,

3s + 19 = s + 21

3s - s = 21 - 19

2s = 2

s = 1

next,

s + 21 =? 3s + 19

1 + 21 equal to (?) 3(1) + 19

22 = 22

so the answer is correct

What are the amplitude and midline?<br> I WILL MARK BRAINLIEST IF CORRECT.

Alex787 [66]

Answer:

see explanation

Step-by-step explanation:

The amplitude is the value from the x- axis to the maximum, thus

amplitude = 2

the midline is the line midway between the minimum and the maximum

Assuming the graph is symmetrical about the x- axis

Then the max is 2 and the min is - 2

y = $\frac{-2+2}{2}$ = $\frac{0}{2}$ = 0

Thus the midline is y = 0
