Answer:
Domain = 0≤m≤20 for mEZ+
Range = $100≤A≤$700 for all values of m
Step-by-step explanation:
Initial amount in the account = $100
Amount saved by beth monthly = $30
Amount in the bank after X month = $100+$30X where X is the number of months beth intend to save up to.
The amount in her bank in her first month = $100+$30(1)
= $100+$30
= $130
Amount saved in the second month will be when X = 2
= $100+$30(2)
= $100+$60
= $160
The amount in the bank will keep increasing by $30 monthly until the 20month.
The amount he will have in her bank in the 20th month will be at when X = 20
= $100+30X
= $100+30(20)
= $100+$600
= $700
This means that her money will be $130 in the first month and will keep increasing until it reaches $700 in the 20th month.
The DOMAIN will be the interval of the time she used in saving. Since she saved for 20months, the domain will be expressed as 0≤m≤20 for mEZ+ where m is the number of month she uses to save.
The Range will represent the amount she saved within the specified time and will be expressed as $100≤A≤$700 for all values of m.
Where $100 is the amount in the account initially and $700 is the amount in the account after 20 months.
Answer: x = 9.611 ; or ; x = 9 11/18 .

Explanation:
________________________________________________
All angles of any triangle must add up to 180 degrees.
So, (10x - 4) + (8x + 3) + 91 = 180 ; Solve for "x" ;
___________________________________________
10x - 4 + 8x + 3 + 81 = 180 ;
Combine the "like terms" on the left-hand side of the equation:
___________________________________________
+10x + 8x = 18x ;
- 4 + 3 + 8 = 7 ;
____________________________
18x + 7 = 180 ;
___________________________________________
Subtract "7" from each side of the equation:
___________________________________________
18x + 7 - 7 = 180 - 7 ;
___________________________________________
to get:
18x = 173 ;
_________________________________
Divide EACH side of the equation by "18" ; to isolate "x" on one side of the equation; and to solve for "x" ;
_________________________________
18x / 18 = 173 / 18 ;
_________________________________
x = 9.6111111111111111....
_____________________________________
Write as: 9.611 ; or; 9 11/18.
