Answer:
x = 2, y = 3
Step-by-step explanation:
x - 3y = - 7 → (1)
x = 5 - y → (2)
Substitute x = 5 - y into (1)
5 - y - 3y = - 7
5 - 4y = - 7 ( subtract 5 from both sides )
- 4y = - 12 ( divide both sides by - 4 )
y = 3
Substitute y = 3 into (2)
x = 5 - 3 = 2
solution is (2, 3 )
A=p (1+r)^t
A future value?
P present value 1050
r interest rate .015
t time 18/12
A=1,050×(1+0.015)^(18÷12)
A=1,073.71
The answer is a because there are two same x values and two x values means it’s not a function
