Answer:
18 cups.
Step-by-step explanation:
We are given that Bernie spends $6.50 on ingredients and cups for his lemonade stand. He charges $1.50 for each cup of lemonade. Inequality that represents this situation:
.
To find number of cups x to make a profit of at least $20 we will use our given inequality.






Therefore, in order to make a profit of at least $20 Bernie need to sell 18 cups of lemonade.
Answer:
The top graph
Solutions:
-2
0
Step-by-step explanation:
The given quadratic function in factored form is

This is a parabola that has x-intercepts at (-2,0) and (2,0)
This parabola opens downward because the leading coefficient is less than 1.
The second function is

This is an absolute value function with vertex at (-2,0).
Therefore the graph that shows the solution to f(x)=g(x) is the top graph.
Hence the solution is x=-2,x=0
C is the closet to the real answer and its a estimate so, C
B because for it to be a function one X value cant have more than one Y value and B is the only one that follows the rule
Given:
Amount = Rs. 9,144
Time = 3 years.
Rate of simple interest = 9%
To find:
The principal value.
Solution:
The formula for simple interest is:

Where, P is principal, r is the simple rate of interest, and t is the number of years.
Putting
in the above formula, we get



We know that,



Divide both sides by 1.27, we get


Therefore, the principal value is Rs. 7200.
