Astudent is using the elimination method to solve the system of equations below. what is the best first step?
5x - 2y = -15
3x 3y = 12
1. multiply the first and second equation by 3.
2. multiply the first equation by 3 and the second equation by 2.
3. multiply the first equation by 2 and the second equation by 3.
4. multiply the first equation by 5 and the second equation by 3.

Determine the number of outcomes in the event. decide whether the event is a simple event or not. upper a computer is used to select randomly a number between 1 and 9 comma inclusive. event upper b is selecting a number greater than 4. event upper b has nothing outcome(s). is the event a simple event? (yes or no) because event upper b has (fewer than, exactly, more than) one outcome.

Consider the following equation -167 + 37 = 49 - 21p select the equation that has the same solution as the given equation. o a. p - 5 + ip = 7 - p ob. +55 + 12p = 5p + 16 c. 2 + 1.25p = -3.75p + 10 d. -14 + 6p = -9 - 6p reset next

What is the range? can’t seem to find it out
