A range is the amount of time from a start of the action up to the end of the action so in your question where a function is created to present the amount of text sent each month. So the best possible restriction of the range is "The range would only include positive integers"
Answer:
k = 
Step-by-step explanation:
Given that r varies directly as p then the equation relating them is
r = kp ← k is the constant of variation
To find k use the condition r = 3 when p = 15, then
3 = 15k ( divide both sides by 15 )
= k , that is
k =
Your answer is B. False. This is because it is not possible to repeat the shape of a regular pentagon and have it tessellate.
I hope this helps!
Answer:
Step-by-step explanation:
Define number of videos purchased as "n" and number of CD's purchased as "c" then we can equation the total purchases and the costs by:
8 nephews:
n + c = 8
Spent $121.53
14.95*n + 16.88*c = 121.53
Substitute one variable as a function of the other. Preference the simpler equation (n + c = 8)
n = 8 - c
=>
14.95*(8-c) + 16.88c = 121.53
119.60 + 1.93c = 121.53
1.93c = 1.93
c = 1
=>
n = 7
*Check:
14.95*(7) + 16.88*(1) = 121.53
im so sorry if this is wrong :/
