Answer:
The rate of change is 
or 1.75. That shows that the cost per video game is $1.75
Step-by-step explanation:
The change in y over change of x or slope can be calculated using the equation:
so take the last two points: (10, 25) and (15, 33.75).
33.75-25=8.75
15-10=5
8.75/5=<u>1.75</u><u> </u><u>(7/4)</u>
x=video games
y=total cost
Since slope is change in y (cost) per change of x (video games), the answer is:
1.75 cost per video game
Answer:
yes
Step-by-step explanation:
y + 4 = 12
Subtract 4 on both sides,
y + 4 - 4 = 12 - 4
y = 8
The expression would be:
3*8+4
3 times 8 plus 4
The inequality you require is
The number of bottles left at the end of each day is 48 - 3x. So it is:-
48 - 3x < 10
Solving the inequality to find the last part of question:-
-3x < 10 - 48
-3x < -38
x > 38/3 = 12 2/3
So answer is 13 days.
Answer:
15
Step-by-step explanation:
-225/-15 = 15
A negative divided by a negative is a positive
225/15 = 15
