The sine has a range -1 to +1 so y goes from 1+2(-1) to 1+2(1) = -1 to 3
Range: -1 ≤ y ≤ 3
20 because if you think about it 2/3 is equal to 20/30.
Answer:
c. (1,-2)
Step-by-step explanation:
by adding them together you can cancel out the y's and solve for x. once you get x, you can plug it into either equation and get y.
hope this helped :)
