Answer:
(-2, 0)
Step-by-step explanation:
y = 2x+4
6x - 3y = -12
Start by simplifying the second equation by dividing everything by 3 (this will make the math easier)...
2x - y = -4
Then, substitute 2x+4 for y into the second equation (this is because y = 2x+4)...
2x-3(2x+4)=-4
Distribute the -3
2x-3(2x)-3(4)=-4
2x-6x-12=-4
Combine like terms
-4x-12=-4
Add 12 to both sides
-4x-12+12=-4+12
-4x=8
Divide both sides by -4
x=-2
Plug -2 back in for x to solve for y:
y = 2(-2) + 4
y=-4+4
y=0
(x, y) = (-2, 0)
Let H = number of hours worked.
He gets $15 for every hour worked, so you need to multiply 15 by h which is written as 15h
You then need to add that to the $200 he gets for showing up.
Total pay = 15h + 200
Answer:
Option A m(3m + 4)(3m - 4)
Step-by-step explanation:
we have
Factor m
![m[9m^{2}-16]](https://tex.z-dn.net/?f=m%5B9m%5E%7B2%7D-16%5D)
Apply difference of squares
we know that
![[9m^{2}-16]=(3m+4)(3m-4)](https://tex.z-dn.net/?f=%5B9m%5E%7B2%7D-16%5D%3D%283m%2B4%29%283m-4%29)
substitute
![m[9m^{2}-16]=m(3m+4)(3m-4)](https://tex.z-dn.net/?f=m%5B9m%5E%7B2%7D-16%5D%3Dm%283m%2B4%29%283m-4%29)
Answer:
2,000ft and the ft of his class
Step-by-step explanation:
Answer:
product is a ⋅ c = 3 ⋅ − 6 = − 18 and whose sum is b = − 7 .
Step-by-step explanation:
Factor
− 7 out of − 7 x .
3 x 2 − 7 ( x ) − 6
Rewrite
−7 as 2 plus −9
3 x 2 + (2−9) x −6
Apply the distributive property.
3 x 2 + 2 x − 9 x − 6
