Answer:
What are the choices?
Step-by-step explanation:
Answer:
y=-x
Step-by-step explanation:
It's going left one by one, meaning the slope is negative and has a slope of -1 or -x.
Let's assume
the number of bags of candy =x
the number of bags of cookies =y
There were 5 more bags of cookies sold than candy
so, we get

Bags of candy cost $5.50
so, total cost of candy is

bags of cookies cost $3.50
so, total cost of cookies is

so,
total cost = (total cost of candy)+(total cost of cookies)
we get
total cost =5.50x+3.50y
so, we can plug

now, we can plug y








now, we can find y



so,
the number of bags of candy =4
the number of bags of cookies =9............Answer
To find where on the hill the canonball lands
So 0.15x = 2 + 0.12x - 0.002x^2
Taking the LHS expression to the right and rearranging we have -0.002x^2 + 0.12x -
0.15x + 2 = 0.
So we have -0.002x^2 - 0.03x + 2 = 0
I'll multiply through by -1 so we have
0.002x^2 + 0.03x -2 = 0.
This is a quadratic eqn with two solutions x1 = 25 and x2 = -40 since x cannot be negative x = 25. The second solution y = 0.15 * 25 = 3.75
