Answer:
Step-by-step explanation:
so you dont know what m is so lets leave that to the side.
first you see its -4 and six. so m = 4 and thats the naswer
Answer:
<em>The minimum number of glasses of lemonade is 70</em>
Step-by-step explanation:
<u>Equations</u>
With the data provided, we can build a model for the profit that Michael gets for selling lemonade.
First, we set up the cost function. He purchased $12 in lemons and $4 in glasses. It makes a fixed cost of $16. He also spends $0.02 per glass of lemonade fot the sugar. Being x the number of glasses of lemonade Michael sells, the total cost is modeled by
C(x)=16+0.02x
The revenue for selling x glasses of lemonade is
R(x)=0.25x
The profit is
P(x)=R(x)-C(x)=0.25x-(16+0.02x)
P(x)=0.23x-16
To make profits:
0.23x-16>0
Solving for x
x>16/0.23
x>69.6
Since x must be an integer
The minimum number of glasses of lemonade is 70
Answer:
56deg
Step-by-step explanation:
A triangle has 180deg.
180 = 68 + 56 + x >> add 68 and 56
180 = 124 + x >> subtract 124 from both sides
56 = x
The missing side is 56deg
Answer:
51= 1/2(160-x)
102=160-x
x=160-102=58
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
We will first look at the end behavior of the graph
Is it down then up which means that the degree is 3 and the coeficcent is positive
this leaves B or C
We then know that the x intercepts are (-2,0) (1,0) (3,0)
The easiest way to proceed from here is just plugging in numbers into our euqation and if the end result is 0 then we got it!
looking at the B we have
-2³-2*-2²-5(-2)+6
this equals 0 which means this is our answer (this elimates C because the only difference between the two equations is the sign on the 5x)
You can also factor it and find the zeroes that way, but it's just more work
