Answer:
A
Step-by-step explanation:
since both equations express y in terms of x we can equate the right sides
x + 7 = - 2x + 19 ( add 2x to both sides )
3x + 7 = 19 ( subtract 7 from both sides )
3x = 12 ( divide both sides by 3 )
x = 4
substitute x = 4 into either of the 2 equations for y
y = x + 7 ⇒ y = 4 + 7 = 11
solution is (4, 11 )
Answer:
5 years
Step-by-step explanation:
Simple interest on a loan of P for t years at rate r per year is ...
I = Prt
4800 = 12,000(0.08)(t)
4800/960 = t = 5
It will take Joel 5 years to pay off the loan.
