Answer:
For every table served, Bradley's pay increases by an average of 4
Step-by-step explanation:
The line of best fit for the graph is y = 4x + 25 ; where, y = total pay and x = tables served
Using the slope intercept relation : y = mx + c ; where, m = slope
y = 4x + 25 ; the slope of the graph is 4
This means the rate of change of x with respect to y is 4 ;
This means for every unit change in x ; y increases by 4
For every table served, total pay increases by 4
x = -7 because, you basically do cross multiplication.
5(x+4)=3(x=2), distribute it and solve it from there.
Answer:
The slope is $0.35/min and it gives the cost per minute of the phone used.
Step-by-step explanation:
We can model this situation with a linear equation of the form

where
is monthly cost,
is the number of minutes,
is the flat monthly fee, and
is the slope of the equation, or in our case, the amount of money charged per minute.
The slope
is

,
in other words, the phone company charges $0.5 per minute.
With the slope in hand, the linear equation becomes
,
and we can find the monthly fee
from that fact that for 300 minutes the cost is $131:

.
Therefore,

where the slope if the equation give the cost per minute of the phone used.
Answer:
30(2+3)
Step-by-step explanation:
1) Find GCF of 60 and 90 (30)
2) Divide both by GCF
3) Put GCF in front of parentheses, then add quotients within the parentheses
