Answer:
m=-2
Step-by-step explanation:
You have to put the equation into y=mx+b form
which would be y=-2x-2
First you would divide 2x+y by 2 so that x+y/2=-1
subtract x on both sides y/2=-x-1
multiply 2 to get y=2(-x-1) simplify y=-2x-2
m=-2
There are different ways to find the solution. (You can find solutions for this equation, but the solutions aren’t infinitely)
Examples
3•2+3•2=12
2+2=4
Or
3•0+3•4=12
0+4=4
Or
3•1+3•3=12
1+3=4
Your answer should be 8.5! if thats not one of your answer choices then round it then your answer would be 9! I hope this helped.
So let’s make the smaller number x and the larger one y....
Set up your equation by following the words signaling mathematical operations from the question.
y = 8 + 4x
y + 4x = 40
Now let’s bring all variables to one side and solve the system if equations with elimination...
y - 4x = 8
y + 4x = 40
Add the equations:
2y = 48
y = 24
Plug the y-value into one of the original equations:
24 = 8 + 4x
16 = 4x
4x = 16
x = 4
And there you have it! The smaller number [x] is 4 and the larger number [y] is 24.
