Answer:
C
Step-by-step explanation:
7x + 3y = 30 (equation 1)
-2x + 3y = 3 (equation 2)
9x = 27 (subtract the two equations to eliminate y)
x = 3 (divide by 9)
7 * 3 + 3y = 30 (Substitute x = 3 into equation 1, it doesn't matter which equation you substitute into)
21 + 3y = 30 (7 * 3 = 21)
3y = 9 (Subtract 21)
y = 3 (divide by 3)
Answer is (3, 3)
Answer:

Answer:
Midline: -2
Amplitude: 1.5
Period: 4
Step-by-step explanation: I got it right on the plato test.
The Midline is the middle of the number of the function.
The Amplitude is from the midline to the highest or lowest point of the function.
The period is the distance on the x axis from the two points.
Hope this helps!
