john bought a used truck for 4,500. he made an agreement with the dealer to put 1,500 down and make payments of 350 for the next 10 months the extra cost paid by taking this deal is equivalent to what actual yearly rate of interest

Answers

So $350 X 10 =$3500

Then, you add the initial $1500,

which means he now has $5000

The difference between $5000 and $4500 is $500,

And $500 is 9% of $4500, 

So the deal is equivalent to a yearly interest of 9%

Hope this helps ! :)

Consider the polynomial P(x)=x⁴+3x³-28x²-36x+144. Write the equation of P in factored form.

Answers

Answer:

P(x)=(x-2)(x-4)(x+3)(x+6)

Step-by-step explanation:

Given: P(x)=x⁴+3x³-28x²-36x+144

It is a polynomial with degree 4.

It should maximum four factor.

Hit and trial error method.

Put x = 2 into P(x)

P(2)=2⁴+3×2³-28×2²-36×2+144

P(2) = 0

So, x-2 would be factor of P(x)

Now divide x⁴+3x³-28x²-36x+144 by x-2 to get another factors

(x^4+3x^3-28x^2-36x+144)/ (x-2) = x^3+5x^2-18x-72

P(x)=(x-2)(x^3+5x^2-18x-72)

Put x = 4

P(4) = 0

now divide x^3+5x^2-18x-72 by x-4

(x^3+5x^2-18x-72)/ (x-4) = x^2+9x+18

P(x)=(x-2)(x-4)(x^2+9x+18)

Now factor x^2+9x+18

\Rightarrow x^2+9x+18

\Rightarrow (x+6)(x+3)

Complete factor of P(x)

P(x)=(x-2)(x-4)(x+3)(x+6)

What is the middle product of (-2x 1)(-3x - 5)? User: Factor 64a2 - 48a + 9.

Answers

What is the middle product of (-2x 1)(-3x - 5)
= (-2x -1)(-3x - 5)
= 6x^2 + 3x + 10x + 5
= 6x^2 + 13x + 5

So the middle product is 13x.

Factor 64a2 - 48a + 9.
64a2 - 48a + 9
(8a - 3) (8a - 3)

Find the slope and y-intercept of the line 6x + 2y = –88 help quick please

Answers

  6x + 2y = -88
- 6x           - 6x
          2y = -6x - 88
           2           2
            y = -3x - 44

Slope: -3
Y-Intercept: -44
6x+2y=-88
2y=6x-88
y=3x-44
y=mx+b
b is the y-intercept, m is the slope
use this next time. please. you need to know this
