Answer:
Step-by-step explanation:
If it costs $114 per year to rent an instrument, then it costs 114/12 to rent it per month, which is $9.50.
For a rental time of 3 years and 5 months, we have 3(114) + 5(9.50) = 342 + 47.50 = $389.50
The equation that represents this total cost in terms of month rented is:
C(m) = 9.50m, where C(m) is the total cost after m, months, rented.
X= 8
Y= -7
If you use elimination:
–3y–4x=–11
3y–5x=–61
Add the two equations and get
–9x=–72
Divide by –9 on both sides
X=8
Substitute 8 in for x
–3y–4(8)=–11
Simplify
–3y–32=–11
Add 32 on both sides
–3y=21
Divide by –3 on both sides
Y=–7
