Answer:
Step-by-step explanation:
In order to do this we need to isolate y by performing the inverse operations on the other values like so...
a) 10x + 5y = 20 ... subtract 10x on both sides
5y = 20 - 10x ... divide both sides by 5
y = 4 - 2x ... we can move the 2x to the right to make it into y = mx + b
y = -2x + 4
b) 3x - 2y = 10 + 4x ... subtract 3x on both sides
-2y = 10 + x ... divide both sides by -2
y = -5 - 0.5x ... move -0.5 to the left so it matches y = mx + b
y = -0.5x - 5
Answer:
A=t+258
Step-by-step explanation:
(-9, -1)
(-9,-1) . -1 because that is the y intercept from the equation.
-9 because when you substitute -2 for x, and multiply by 4, you get -8. Then you subtract one, making the x value -9.
Therefore, the ordered pair of the solution is (-9,-1)
Hope this helps, please consider marking branliest if it did.
Multiply both sides by negative four to get rid of the fraction
j+18=-32
subtract 18
j=-50
