50 is the number because it is a great number to compare it to.
Rate of change, or slope, or rise over run, or ‘m’ is the difference between a pair of y-coordinates over the difference between a pair of x-coordinates.
The formula for rate of change or slope is:
m=(y2-y1) / (x2-x1)
All we have to do is take two pairs of coordinates from the table and solve for the slope (m).
Let’s just choose the first two coordinates: (1, 5) and (2, 5).
m=(5-5) / (2-1)
m=(0)/(1)
m=0
So, the rate of change is 0; there is no rate of change. There is 0 rise per 1 unit of run.
C+p=15
5c+7p=91
multiply 5 to 1st equation and subtract it from 2nd
multiply 5 to 1st equation to get
5c+5p=75
now subtract this from 2nd equation
thats 2p=16
so
p=8
now we find c from
c+p=15
c=7
The number of customers who visited more on first day = ( 5 x - 2)
<h2>
248 more people visited on the first day. </h2>
Step-by-step explanation:
The total number of customers visiting on first day = (6 x - 3)
The total number of customers visiting on second day = (x - 1)
The difference in the number of customers
= Number of customer visiting ( First day - Second Day)
= (6x - 3) - (x- 1) = 6 x - 3 - x + 1 = 5 x - 2
So, the number of customers who visited more on first day = ( 5 x - 2)
Now, when x = 50, ( 5 x - 2) = (5 (50) - 2) = 250 - 2 = 248
Hence, 248 more people visited on the first day.
