Answer: D
Step-by-step explanation:

Let's take one of the equations and solve for a variable to use the substitution method.

Now replace this in the first equation.

Separate the terms.

Solve 20/5

Subtract 4 from both sides to isolate y.


Solve the difference.



Multiply by the reciprocal or the inverted fraction that is next to y to isolate it.


Now, in order to find x, replace y in any of the two equations.

Answer:
C) Apply the distributive property
Answer:
You can't do that is an error if you want to do that you would get it wrong but the only way to do that is 4x2+12x135 which equals 1628
Step-by-step explanation:
I multplyed 4x2 first then 12x135 then added both of them together which gave me 1628
Answer:
y= -5x +7
Step-by-step explanation:
We can see points on the graph:
The function in general form is:
Let's find the slope and y-intercept as per identified points on the graph:
b= y- mx
- b= - 3 -(-5)*2= -3 +10= 7
Based on the found values of m and b, the given line is:
