John owns a lawn mowing and landscaping business. the income from the business is given by the function f(x) = 2x + 54, where f(x) is the income in dollars and x is the area in square meters of lawn mowed. if john has earned {204, 344, 450, 482} dollars in the last four months, what are the corresponding areas of lawn he mowed? a. {75, 145, 198, 214} b. {84, 123, 204, 254} c. {70, 135, 184, 195} d. {80, 110, 185, 246} e. {95, 148, 175, 206}

ANSWER

A. {75, 145, 198, 214}

EXPLANATION

From the given information,the income is given by the function

where f(x) is the income in dollars and x is the area in square meters of lawn mowed.

To find the area that corresponds to John's earnings, we equate the function to the earnings and solve for x.

For the area that corresponds to 204, we have

For the area that corresponds to 344, we have:

For the area that corresponds to 450, we have

For the area that corresponds to 482, we have

Therefore the correct answer is A.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
