By replacing you get:
5*7-2*11+3*(-1) = 35-22-3= 10
so the answer is 10.

The coordinate of the vertex is; (h, k) = (3, -5)
The final equation of the parabola is; y = 5(x - 3)² - 5
<h3>How to find the vertex of a Parabola?</h3>
The vertex is the coordinate of the crest or trough of the curve. Now, in the given graph, we only have a Trough which is the lowest point of the graph.
The coordinate of the vertex is; (h, k) = (3, -5)
2) Since the general equation is;
y = a(x - h)² + k
We will have;
y = a(x - 3)² - 5
At x = 2, y = 0. Thus;
0 = a(2 - 3)² - 5
a - 5 = 0
a = 5
3) The final equation of the parabola is;
y = 5(x - 3)² - 5

The answer is p+q
Step-by-step explanation:
Answer:
∠1 = 112°
Step-by-step explanation:
∠2 = ∠3 = 112° ( corresponding angles )
∠1 = ∠2 = 112° ( vertically opposite angles )
