Answer:
3,6,-2
Step-by-step explanation:
a+2a+b = 7
2a^2b = -36
a*2a + ab + 2ab = 0
or, a(2a+3b) = 0
so, b = -2a/3
Solve those and you find 3,6,-2

<h3>What is Interest Rate?</h3>
This refers to the amount of money that is added to a loan collected by a person, for when he makes repayment.
Hence,
Given that
- PMT monthly payment 1558.09
- R interest rate 0.05875
- K compounded monthly 12 because the payment is monthly
- N time 20 years
- Pv present value?
We use the formula Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv= 1,558.09×((1−(1+0.05875÷12)^(−12×20))÷(0.05875÷12))
=219,684.92
Next thing to do is make a subtraction to get the down payment:
267,900−219,684.92=48,215.08
Then the percentage would be:
48,215.08÷267,900= 18% approx.

X = 3
Combine like terms: -4 + -5 = -9
-9 + 6x + -3x = 0
Combine like terms: 6x + -3x = 3x
-9 + 3x =0
Solving -9 + 3x = 0
Solving for variable ‘x’
Moving all terms containing my x to the left, all other terms to the right
Add ‘9’ to each side of the equation -9 + 9 + 3x = 0 + 9
Combine like terms: -9 + 9 = 0
0+3x=0+9
3x = 0 + 9
Combine like terms: 0 + 9 = 9
3x = 9
Divide each side by ‘3’.
X = 3

Answer:
The total cost (in dollars) of p pens is C = 0.09 p
Step-by-step explanation:
The cost of each pen = 9 cents
Now, 1 cent = $0.01 cents
⇒ 9 cents = $0.09
So, the cost of 1 pen = $0.09
The number of pens purchased= p
Let the total cost of p pens = c
Also, the cost of p pens = p x ( Cost of 1 pen) = p ( $0.09) = 0.09 p
or, C = 0.09 p
Hence the total cost (in dollars) of p pens is C = 0.09 p.
