Answer:
c 20
Step-by-step explanation:
You make 53 a day plus 3.75 per sale
Income = 53+ 3.75 s
You want to make at least 128
128 ≤ 53+ 3.75 s
Subtract 53 from each side
128 -53 ≤ 53-53 +3.75s
75≤ 3.75s
Divide by 3.75 on each side
75/3.75≤ 3.75s/3.75
20 ≤ s
You must make at least 20 sales
With the given data, the first step to take is to use MS excel to plot the data then determine the trendline in which the equation's r2 value is closest to 1. From the plot obtained from Excel, the plot is a second degree polynomial and not an exponential function. the answer hence is no.
For this case we have a direct variation of the form:
Where "k" is the constant of proportionality. To find it, we use the following data:
Substituting:
Clearing the value of k:
Thus, the direct variation is given by:
For
we have:
Answer:
The value of the direct variation for is: 
Answer: (x-6)(x+1)
Step-by-step explanation:
Sum : x2 − 5 x- 6
x2 + x-=6 x − 6
factor pair: x 2 + x − 6 x − 6
x( x+ 1 ) − 6 ( x + 1 )
rewrite from: x (x + 1 ) − 6 ( x + 1 )
(x-6)(x+1)
