Answer:
D
Step-by-step explanation:
Vertex form is y=a(x-h)^2+k where (h,k) is vertex
So replace h with -3 and k with 2
y=a(x--3)^2+2
y=a(x+3)^2+2
So the only choice it could be is D

huh????
Step-by-step explanation:
Answer:
z = 56 degrees
Step-by-step explanation:
y = 124 because y is adjacent to 124 degrees
y + z = 180
180 - 124 = 56
The value of x is x=2.57338 and x=−0.906718
<h3>What is equation?</h3>
An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.
Given:
3x²-5x-7=0
Using the discriminant method,
a = 3, b = -5, and c = -7
x= -b± √b²-4ac / 2a
x= 5 ± √25 + 84/ 6
x= 5± √ 109
Hence, x=2.57338 and x=−0.906718
