Answer:
$411.30 in a month with 30 days
Step-by-step explanation:
$4.57 times 3= $13.71 per day
Assuming there are 30 days in a month, $13.71 times 30= approximately $411 monthly, or more specifically $411.30 in a month with 30 days.
Answer: 7) Max: y = 52
8) Min: y = -51
<u>Step-by-step explanation:</u>
The Max/Min is the y-value of the intercept.
- Max is when the a-value is negative.
- Min is when the a-value is positive.
First, find the x-value of the vertex using the Axis of Symmetry formula:
x = -b/2a. Then plug the x-value into the equation to find the y-value.
7) y = -2x² - 16x + 20
↓ ↓ ↓
a= -2 b= -16 c=20

Max: y = -2(-4)² - 16(-4) + 20
= -2(16) + 64 + 20
= -32 + 84
= 52
*********************************************************************************************
7) y = x² + 12x - 15
↓ ↓ ↓
a= 1 b= 12 c= -15

Max: y = (-6)² + 12(-6) - 15
= 36 - 72 - 15
= 36 - 87
= -51
-8 and 2
The expression is factorable and is equal to (x+8)(x-2). Using the zero product property, x=-8 because (-8)+8 equals zero and x=2 because 2-2 equals zero.
