Question:
Is 8 = -4 + 2y a function or not?
Steps on how to solve:
1. Add 4 to both sides
2. Simplify,
3. Then, divide both sides by 2
4. Simplify,
- 2 = y
- So yes it is a function!
Hope that helped!!

"raise at least $140" tells you that, whatever the variables may be, the french club's profit needs to be 140 or more
they're selling pastries at $3.50 each, so we'll say that p is the number of pastries
140 >/= 3.50p
$140 must be greater than or equal to the profit from sold pastries
then just solve the inequality from there by isolating your variable:
140 >/= 3.50p
divide both sides by 3.50
40 >/= p
so they must sell at least 40 pastries to raise $140 dollars
Answer:
131.25
Step-by-step explanation:
There are 3 trapezoids that you need to find its area, all the areas are the same.
Area of trapezoid:
A=(a+b)/2*h
a = 20
b = 15
h = (20-15)/2 = 5/2
A = (20+15)/2*5/2
A = 43.75
3A (3 gardens) = 131.25
Option I
(3x+4)cm =(2x+10)cm
3x-2x=6
x=6
Option II
(3x+4)= (x+12)
3x-x=12-4
2x=8
x=4
Option III
(2x+10)= (x+12)
2x-x=12-10
x=2
