Answer:
Break down the problem into these 2 equations.
a+6=3a+2
a+6=3a+2
a+6=2a
a+6=2a
Solve the 1st equation: a+6=3a+2a+6=3a+2.
a=2
a=2
Solve the 2nd equation: a+6=2aa+6=2a.
a=6
a=6
Collect all solutions.
a=2,6
a=2,6
Step-by-step explanation:
Answer:
y=-4/3x-8/3
Step-by-step explanation:
Use the slope formula y2-y1/x2-x1
Finding the slope, 4-(-4)/-5-1 = 8/-6 = -4/3
y=-4/3x + b
Substituting,
-4=-4/3+b
-12/3+4/3=b
b=-8/3
y=-4/3x-8/3
Answer:
9.68%
Step-by-step explanation:
cost of car = $35,000
down payment = $3,000
number of monthly instalments= $65
amount in every monthly instalment= $539.99
total monthly payment= 65×539.99= 35099.35
amount to be paid apart from downpayment= $35,000-3000= 32,000
therefore total interest paid in 65 months= 35099.35-3200= $3099.35
now, monthly interest rate 
⇒ r= 9.68%
