Answer:
When they send 25 texts each, their bills will be equal
Step-by-step explanation:
Let the number of text messages that makes their bill equal be x
Jorge will have a bill of = 50 + x(1) = 50 + x
Jillian will have a bill of = 72 + 0.12(x) = 72 + 0.12x
Since their bills will now be equal, we equate both
50 + x = 72 + 0.12x
72-50 = x-0.12x
22 = 0.88x
x = 22/0.88
x = 25 texts
The function I = 19n is a linear function
The reasonable domain of the function is [0,21]
<h3>How to determine the domain?</h3>
The function is given as:
I = 19n
The smallest value of n is 0 i.e. the smallest number of ticket sold is 0
The maximum capacity is 400.
So, we have:
19n = 400
Divide both sides by 19
n = 21.05
Remove the decimals
n = 21
Hence, the reasonable domain of the function is [0,21]

A scale factor is a number which scales or multiplies a quantity, e.g a scale factor of two would mean to multiply whatever the value is by two. Since there are no specific values for LMN and OPQ, the scale factor of the two would be 1/1 because they are one quantity with respect to the other.
The ANWSER is unrestricted domain
Step-by-step explanation:
add up both equations
2x -y + 3x + y -13 = 0 (y will eliminate -y)
5x -13 = 0
5x = 13
x = 13/5 now use this value to find y
2 × 13/5 -y - 4 = 0
26/5 - y -4 = 0
26/5 - 4 = y
6/5 = y
