Answer:
x=-2 y=3
Step-by-step explanation:
The substitution is basically given to you. Exchange x from the second equation with y-5
Once that is done and you combine the parentheses you get:
2y-10+y=-1
Add 10 on both sides of the equal sign
You get:
3y=9
Divide both sides by 3
You get:
y=3
To check your work you can substitute y in the second equation with 3 and solve it that way to get x=-2 (x equals negative two)
Answer:
it is B
Step-by-step explanation: 25 goes in 1 hundred 4 times And that gets us to 24
Answer:
y=2
Step-by-step explanation:
Answer:
The slope would be: -2
Step-by-step explanation:
To find the slope of these two points:
(0,4) and (3,-2)
You would have to use the formula of slope to find it.
The slope formula is:
<h2><u>y₂ - y₁ </u></h2><h2>X₂ - X₁ </h2>
So subsitute in Those two points
(0,4) would be your (x₁ , y₁)
(3,-2) would be your (x₂ , y₂)
So your formula witht he subsituted #'s in it would look like:
<h2><u>-2 - 4</u></h2><h2>3 - 2</h2>
Your answer would be:
<h2><u>-6</u></h2><h2> 3</h2>
Simplified, it is -2
<h3>So your slope is -2</h3>
