Sounds like you’re dealing with absolute value.
1. Cookies
2. Bananas
3. Bananas and ice cream are the closest
The answers to the question are are the equations
y = 0.08x²-1.6x+13
y = 0.08(x-10)²+5
<h3>How to solve for the system of equations</h3>
David starts at (20, 13) and skates along a path that can be modeled by a quadratic function with a vertex at (10, 5).
Vertex form of quadratic function is
y = 
13 = a(x-10)²+5
let x = 20
a(20-10)²+5
13 = 100a + 5
take like terms
13 - 5 = 100a
8 = 100a
divide through by 100
a = 0.08
hence the equation would be
y = 0.08(x-10)²+5

1ft=12in
1ft/12in=1
3.5ft=?in
1ft:12in=3.5ft:?in
1ft/12in=3.5ft/?in
times both sides by 12?in
1?=42in
answer is 42 in
or you could just do
3.5 times 12=42 inches

Step-by-step explanation:
Answer:
The correct answer is the first solution set.
Step-by-step explanation:
If we substitute -20 into the equation we get
-20+17≤-3
-3≤-3
So,the inequality is right.
We can check the second one
14+17≤-3
31≤3 The inequality is false.
We can check the last one
-20+17≤-3
-3≤3 It works however there is a difference between the first one and the last one and that is the sign.For the first one there x≤-20 meaning the greatest number x can be is -20.For the last one x≥-20 which means -20 is the least value x can be.
If we substitude -21 into the equation we get
-21+17≤-3
-4≤-3
The inequality is false because -4 is not smaller than -3.
So,the right answer is the first solution set.
