If the graph of the function g defined by g(x)=-2x^2+9. is translated vertically downward by 8 units, it becomes the graph of a function f. find the expression for f(x)

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
