Answer:
18. 20,000.
19. 0
7. 1
11. 101
Step-by-step explanation:
18. I think is stays the same, because an integer is a number that is not a fraction. So still 20,000.
19. Sea level is at zero altitude. So answer is 0.
7. |17-16| = |1| = 1. The lines around it are called absolute value signs and mean to make the answer positive.
11. |-101| = 101. As said before the lines mean to make the inside part positive.
For the point (2,5), 2 = x and 5 = y.
5= -2(2)
5 = -4
So no, the first one y=-2x would not work since -4 is not equal to 5.
5=2+3
5=5
Yes, that second one y=x+3 does work since 5 is equal to 5.
