Symmetric since it goes up and back down the same amount of dots.
X= 8
y= 8root2
........................
(-7x)(9-2x)
-63x+14x
-49x is the answer
15) It is given that the charge of the waffle cone = $1.85
Charge per scoop of an ice cream = $0.60
Let C be the total cost.
So, total charge of one wafflce cone ice cream = charge of the waffle cone + (0.6 times number of scoops
C = 1.85 + 0.6x
16) To find the cost for 6 scoops of ice cream, put x = 6 in the above expression and simplify.
C = 1.85 + 0.6(6)
= 1.85 + 3.6
= 5.45
Hence, cost of 6 scoops of ice cream = $5.45.
Answer:
Brand A costs less per diaper
Step-by-step explanation:
To determine if it is the better deal, we need the cost per diaper. To find the Cost per diaper, take the total cost and divide by the number of diapers
