- System Of Equations

-----------------------------------

- Isolate x for x + x + 10 = 10: x = 0
For y = 10
Substitute x = 0
Y = 0 + 10
0 + 10 = 10
y = 10
X = 0
Y = 10

Answer:
(a)0.75x+1200=3.50x
(b)
(c)0.75x+1200<3.50x
(d)
It means the store needs to sell more than 436 funnel cakes to make a profit
Step-by-step explanation:
Given the Cost and revenue function of John boy and Mary Ellen's food stand below:
C= 0.75x+1200.
R=3.50x
(a)When Cost = Revenue
Then:
0.75x+1200=3.50x
(b)To solve the equality from part (a) above
0.75x+1200=3.50x
Collect like terms
1200=3.50x-0.75x
1200=2.75x
Divide both sides by 2.75

When Cost equals revenue, it is the <u>Break-Even Point.</u> It means the food stand will have to sell 436 funnel cakes to break even.
(c) When Cost is Less than Revenue

(d)Solving the inequality
C(x)<R(x)
0.75x + 1200<3.50x
Collect like terms
1200<3.50x-0.75x
1200<2.75x
Divide both sides by 2.75


It means the store needs to sell more than 436 funnel cakes to make a profit.
Answer:
c
Step-by-step explanation:
Because it shows 6 with the 10 therefore there are going to be 10 zeros so thag would mean that its c
Add 50.7+5.6=56.3 give you the answer to o help out the feet of the pelican traveled
44 feet. Assuming you meant 5.5 inches, you can simply multiply 8 by the amount of inches you have. 8 x 5.5 = 44.
