Answer:
x = ±
Step-by-step explanation:
We have been given the quadratic equation;
The first step is to subtract 50 from both sides of the equation;
Multiplying both sides by -1 yields;
The final step is to obtain square roots on both sides;
Therefore, x = ±
Equations are given,
y= x+2
<span>
y= -4x+7
As you can see both the expressions, x+2 and -4x+7 are equal to "y". That means they are equal to each other too.
So let's equal them and solve it.

<span>
Now we have x's value we will plug it in the first equation to find "y".
