Using linear functions, it is found that:
- Using the graph to find the solutions of the system, we have that the total cost would be of $40 at both shops.
A <em>linear function</em> has the following format:
In which:
- m is the slope, which is the rate of change.
- b is the y-intercept, which is the fixed value.
At Greenpoint Florist, $1 is charged per rose, plus $30 for the vase, hence, the equation is:
At Ashley's Flowers, $3 is charged per rose, plus $10 for the vase, hence, the equation is:
At the end of this answer, the two solutions are graphed, and it is found that when 10 roses are sold, the total cost would be of $40 for at both shops.

I am assuming you wrote the problem wrong. Is it a^2?
A^2 -4A-21=0
(A-7)(A+3)=0
A=7 A=-3, ignore the negative number because it doesn't make sense if you plug in for a.
length=a+3=7+3=10
Width=7=a
Replace x by -2, then we got
2•3•(-2)
= -12
If f(-12) then f(x) = -12
Answer:
Mean: 11.875 or 11.9
Median: 14
Step-by-step explanation:
Mean = all numbers added up and then divided by the amount of numbers
Median = numbers ordered smallest to largest and then he middle number is your median, if there are two middle numbers then add those and divided by 2
