Select the correct answer from each drop-down menu. A system of equations and its solution are given below.

System A

Complete the sentences to explain what steps were followed to obtain the system of equations below.

System B

To get system B, the
equation in system A was replaced by the sum of that equation and
times the
equation. The solution to system B
the same as the solution to system A.

is should be y = 5x

step-by-step explanation:

correct me if im wrong

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
