What is the solution to the following system? (x+2y+z=9
X-y+32 = 13
2z= 10
x = 10, y = 2, z = 5
x= 4, y = 2, z = 5
x = 0, y = 2, z = 5
x = 4, y = 6, z = 5

The size of a certain cell is 2.5*10^-9m. another cell is 1.5*10^3 times larger. how large is the larger cell in scientific notation?

Gabriel determined that his total cost would be represented by 2.5x + 2y – 2. his sister states that the expression should be x + x + 0.5x + y + y – 2. who is correct? explain.

The function y= x - 4x+ 5 approximates the height, y, of a bird, and its horizontal distance, x, as it flies from one fence post to another. all distances are in feet. complete the square to find and interpret the extreme value (vertex). select two answers: one extreme value and one interpretation.
