Answer:
13
Step-by-step explanation:
You just count by adding 3 every time
Answer:
x=1
Step-by-step explanation:
4 - 5(3- 2x) = -2x + 1
Distribute
4 - 15 +10x = -2x+1
Combine like terms
-11 +10x = -2x+1
Add 2x to each side
-11+10x+2x = -2x+2x +1
-11+12x = 1
Add 11 to each side
-11 +11 + 12x = 11+1
12x = 12
Divide each side by
12x/12 = 12/12
x = 1
The vertex is halfway between 700 and 800, and the x value of the vertex is right over the 10. So since the x value represents dollars, the maximum (vertex) is 10$ each for 750$
