Find the solution to the system

Answer:

(-2, 1)

Step-by-step explanation:

You can read the solution from graph. The solution is where the two lines intersect. That happens in point (-2, 1).

---

<u>Alternative:</u>

If you want to be sure, you can alway double check by solving the system of equations.

First equation: y = \frac{1}{2}x + 2

Second equation: y = -\frac{1}{2}x

Substituting y in first equation with y from second.

y = \frac{1}{2}x + 2

-\frac{1}{2}x = \frac{1}{2}x + 2

Adding \frac{1}{2}x on both sides.

-\frac{1}{2}x + \frac{1}{2}x = \frac{1}{2}x + 2 + \frac{1}{2}x

0 = 1x + 2

0 = x + 2

-2 = x

Substituting x with -2.

y = -\frac{1}{2}x

y = -\frac{1}{2}(-2)

y = 1

As you see you get the same result as from reading the graph, (-2, 1).

What are the solutions to the equation 3(x – 4)(x + 5) = 0?
iris [78.8K]

Answer:

x=4 and x= - 5

Step-by-step explanation:

In order to solve this we should re-arrange the equation:

(x-4)(x+5)=\frac{0}{3}

This is equal to:

(x-4)(x+5)=0

Then we can seperate this into:

(x-4)=0\\(x+5)=0

So solving for x in both cases we get

x-4=0 \\x=4\\And\\x+5=0\\x=-5\\
