Answer:
20
Step-by-step explanation:
We have two simultaneous equations.
(1) y = 2x + 50
(2) y = 4.5x
1. Subtract (1) from (2)
0 = 2.5x - 50
2. Add 50 to each side
2.5x = 50
3. Divide each side by 2.5
x = 20
Pilar must sell 20 items to break even.
x = -2
so 0.5 x (2-(-2)) = 0.5 x 4 = 2
Answer:
A.
Step-by-step explanation:
Since the associate property is grouping and since the only that groups the number differently is A.
6(1/3 x 7/5) changes to (6 x 1/3) 7/5
Hope this helps :)
Consider the following table.
This is a linear function. They vary directly with each other.
x increasing by 1 each time.
y increases by 4 each time.
I hope this helps!
