If you are trying to solve for X the answer is -9
Answer:

Step-by-step explanation:
Use Vertex form: 
Given: vertek (h, k)=(-1, 2)

A point:(x , y) = (3, 6)

16a=4, a=1/4
The equation is : 
STEP 1:
Discount $= Price times discount %
=$5.00 * 50%
=$5.00 * 0.50
=$2.50 discount amount
STEP 2:
Sale price= Original $ - Discount amount
=$5.00 - $2.50
=$2.50 sale price
ANSWER: Discount amount is $2.50 and the sale price is also $2.50.
Hope this helps! :)
Answer:a=4
Step-by-step explanation:
Simplifying
4a + -5 + 2a + 9 = 28
Reorder the terms:
-5 + 9 + 4a + 2a = 28
Combine like terms: -5 + 9 = 4
4 + 4a + 2a = 28
Combine like terms: 4a + 2a = 6a
4 + 6a = 28
Solving
4 + 6a = 28
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-4' to each side of the equation.
4 + -4 + 6a = 28 + -4
Combine like terms: 4 + -4 = 0
0 + 6a = 28 + -4
6a = 28 + -4
Combine like terms: 28 + -4 = 24
6a = 24
Divide each side by '6'.
a = 4
Simplifying
a = 4
Answer:
Part A) The zero's of the function are 
Part B) The solution set is the interval ![[0.84,7.16]](https://tex.z-dn.net/?f=%5B0.84%2C7.16%5D)
Step-by-step explanation:
we have

Using a graphing calculator
Part A) What are the zeros of the inequality to the nearest hundredth?
The zero's of the function are the values of x when the values of the function are equal to zero
see the attached figure
The zero's of the function are

Part B) What is the solution set for the inequality?
The solution set is the interval ![[0.84,7.16]](https://tex.z-dn.net/?f=%5B0.84%2C7.16%5D)
All real numbers greater than or equal to 0.84 and less than or equal to 7.16
