Answer: 16) Vertex = (3, 39)
17) Vertex = (-2, -17)
<u>Step-by-step explanation:</u>
When given the standard form of a quadratic equation: ax² + bx + c
use the Axis of Symmetry formula to find the x-value of the vertex. x = -b/(2a)
Then plug the x-value into the given equation to find the y-value.
16) y = -x² + 6x + 30
↓ ↓ ↓
a= -1 b=6 c=30
Max: y = -(3)² + 6(3) + 30
= -9 + 18 + 30
= -9 + 48
= 39
Vertex: (3, 39)
***************************************************************************************
17) y = 3x² + 12x - 5
↓ ↓ ↓
a= 3 b=12 c= -5
Min: y = 3(-2)² + 12(-2) - 5
= 3(4) - 24 - 5
= 12 - 29
= -17
Vertex: (-2, -17)
Answer:
-8
Step-by-step explanation:
-18 + -8 = -26

Answer:
p = q/5 - 9r/5
Step-by-step explanation:
Step 1: Write equation
5p + 9r = q
Step 2: Solve for <em>p</em>
<u>Subtract 9r on both sides:</u> 5p = q - 9r
<u>Divide both sides by 5:</u> p = q/5 - 9r/5
