Answer:
I think C
Step-by-step explanation:
Let's work this problem out!
First: 5(x) - 26 - x + 50 = ?
Second: 4(x) - 76 = ?
Third: 4 = ?
↑
(Solve Step 3)
Fourth: x - 19 = 0
↑
(Add the number 19 to each of your sides for Step 4)
Finally we get to your answer
19 + 0 = 19 ; 19 - 19 = 0
So, therefore the value of "x" is 19
Comparing to the standard equation, the parabola with a vertex at (-2,0) is given by:
y = (x + 2)²
<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
In this problem, we have that h = -2 and k = 0, and all the options have leading coefficient a = 1, hence the equation is:
y = (x + 2)²
