A swimming pool 50 meters long and 16 meters wide can hold 4,000 cubic meters of water. Which equation can be used to solve for the depth of the pool? A. 50 x 16 x d = 4,000 B. 4,000 x 50 = 18 divided by d C. 4,000(50 x 16) = d D. 50(d divided by 16) = 4,000

Consider the following equation. 1/2x^3+x-7=-3sqrtx-1 approximate the solution to the equation using three iterations of successive approximation. use the graph below as a starting point. a. b. c. d.

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
