Answer:
Total amount paid = 20 + 15x
11 months
Step-by-step explanation:
Annual fee = $20
User charge per month = $15
Number of months = x
Total amount paid = 20 + 15x
Felix prepaid = $185
Total amount paid = 20 + 15x
185 = 20 + 15x
Subtract 20 from both sides
185 = 20 + 15x
185 - 20 = 20 + 15x - 20
165 = 15x
Divide both sides by 15
x = 165 / 15
= 11
x = 11 months
Answer:
a)g: 3x + 4y = 10 b) a:x+y = 5 c) c: 3x + 4y = 10
h: 6x + 8y = 5 b:2x + 3y = 8 d: 6x + 8y = 5
Step-by-step explanation:
a) Has no solution
g: 3x + 4y = 10
h: 6x + 8y = 5
Above Equations gives you parallel lines refer attachment
b) has exactly one solution
a:x+y = 5
b:2x + 3y = 8
Above Equations gives you intersecting lines refer attachment
c) has infinitely many solutions
c: 3x + 4y = 10
d: 6x + 8y = 5
Above Equations gives you collinear lines refer attachment
i) if we add x + 2y = 1 to equation x + y = 5 to make an inconsistent system.
ii) if we add x + 2y = 3 to equation x + y = 5 to create infinitely system.
iii) if we add x + 4y = 1 to equation x + y = 5 to create infinitely system.
iv) if we add to x + y =5 equation x + y = 5 to change the unique solution you had to a different unique solution
