Solve the following system by graphing. What is the solution?<br> y=-4x-2<br> y=2x+4
Hunter-Best [27]

Answer:

The answer to your question is (-1, 2)

Step-by-step explanation:

Data

       y = -4x - 2                 Equation l

       y = 2x + 4                  Equation ll

Process

-Graph equation l (green line)

 Plot the point (0, -2)

 Starting from this point plot the point (1, -4), this point comes from the slope.

-Graph the equation ll (blue line)

 Plot the point (0, 4)

 Plot the point (1, 2) starting from the previous point.

-The solution is the point where the lines cross. This point is (-1, 2)

What is x in this equation- 3/2x-7=-11
Sunny_sXe [5.5K]

3/2x-7=-11


We move all terms to the left:


3/2x-7-(-11)=0



Domain of the equation: 2x!=0


x!=0/2


x!=0


x∈R



We add all the numbers together, and all the variables


3/2x+4=0


We multiply all the terms by the denominator



4*2x+3=0


Wy multiply elements


8x+3=0


We move all terms containing x to the left, all other terms to the right


8x=-3


x=-3/8


x=-3/8
