Answer:
5
Step-by-step explanation:
A rule is that if there is a negative sign before the parenthesis and in the parenthesis next to each other, you make it a addition sign. So it would be 4+1. Which is 5.
Answer:
28 - 8= 20 ÷ 5 = 4
Step-by-step explanation:
Use distributive property. The answer is 4
You get all of the numbers and turn them too zeros except the first one
D. I’m pretty sure!!!!!!!
So there are two ways.
First you could solve for y and plug it into the calculator. one equation for y1 and another for y2. Then go 2nd trace and press 5 and then press enter 3 times to find the intersection.
the second way is to solve by hand. I would suggest solve the first equation for y and plug the equation solved for y into the other equation. so y = -3x + 9 and 3x-5y=15. Then you could do 3x - 5(-3x+9) = 15. Finally solve for x and plug in x into both equations to see if you get the same y value.
The answer should be (10/3, -1)
