Answer:
b) y=2x-3 y-int.=-3 x= 1/2 (think of rise over run)= up 2 over 1. C) IDK D) y=2/4+3 E)7/2-8
Step-by-step explanation:
<h2>when you solve in slope intercept form ex. 3x+4y=12 move 3x by subtracting to the other side. 3x-3x=0 cancel then your left with 4y=-3 (you moved to both sides)+ 12 divide the equation by 4. left with 4divided by 4 cancels left with y= -3+12 divided by 4= y=3/4+8</h2><h2 /><h2>Remember if positive subtract if negative number add to both sides.</h2>
Answer: x=-4, y=-7
Problem:
4x-6y = 26
5x-4y=8
You can use substitution or elimination to solve the problem. I’m going to use elimination.
Multiply by -2 => -8x+12y = -52
Multiply by 3 => 15x- 12y = 24
Add those equations together:
7x=-28
x=-4
Plug that into one of the original equations to get y.
4(-4)-6y=26
-16 - 6y=26
-6y=42
y=-7
Check for the other equation to see if this is true. Which in this case it is. So that’s your answer. x=-4, y=-7
15 dollars from 1 sidewalk

Dionte needs to shovel 10 sidewalks
Answer:
b
Step-by-step explanation:
2(h-8)-h=h-16
step 1 distribute 2 to whats in the parenthesis
2h-16-h=h-16
step 2 combine like terms
h-16=h-16
add 16 to each side
h=h
subtract h from each side
0=0
this would have an infinite amount of solutions
