This is approximately 4000 miles from the center of the Earth. How much would this object weigh 4800 miles from the center of the Earth? (Round to the nearest tenth of a pound.)
A. 1584 pounds B. 763.9 pounds C. 1004.2 pounds D. 916.7 pounds
Fill in the blank. Then write an addition problem with addends and the sum that describes the situation.A gain of $4 followed by a loss of $9 results in a 
.
A. loss of $13; -4 + (-9) = -13 B. loss of $5; 4 + (-9) = -5 C. gain of $13; 4 + 9 = 13 D. gain of $5; -4 + 9 = 5
If the function is one-to-one, find its inverse. If not, write "not one-to-one."{(13, -6), (-5, 5), (6, -20)}
A. {(13, 5), (13, -5), (-20, 6)} B. {(-6, 13), (5, -5), (-20, 6)} C. not one-to-one D. {(-6, 13), (6, -5), (-20, 5)}
