Step-by-step explanation:
A. land reduces wind power
Answer:
It will take 10 hours
Step-by-step explanation:
first you subtract 150 from 900 (900-150) to get 750. next you divide 750 by 75 since that is the rate the tickets are being sold (750÷75) which would equal to 10.
1) It is a horizontal line through (0, 2) with no x-intercept. The slope is zero.
2) It is a decreasing line that only goes through the origin on the axis. The slope is -1/2.
3) It is an increasing line that crosses the y-axis at 4 and the x-axis at 4. The slops is 1.
4) is is a vertical line going through (-1, 0). The slope is undefined.
