Answer:

3x (x-3)

Step-by-step explanation

3x^2 - 9x + 0

The equation.

3x^2 - 3^2 × x

What I did here is that I factored out 9x to 3^2 times x.

3x (3x^2 all over 3x - 3^2 × x/ all over 3x)

So that way I can divide the number in the parentheses by 3x to take 3x out of the parentheses to factor out.

3x (x^2-1 - (3^2-1) )

You simplify to get the final answer.

3x (x-3)

Final Answer.

I hope this helps!!!!

The repayment schedule is for a $1,300 loan at 7.5% for 6 months. What is the amount for interest at payment 5?

Jlenok [28]

Answer:

$2.77

Step-by-step explanation:

Here's one way to do it.

Data:

We must express the interest rate on a monthly basis.

i = 7.5 %/yr = 0.625 %/mo = 0.006 25

A = $1300

n = 6 mo

A. Monthly payments

The formula for the monthly payment (P) on a loan of A dollars that is paid back in equal monthly payments over n months, at an annual interest rate of i % is

$P = A(\frac{i}{1-(1+i)^{-n}})$

Calculation:

$P = 1300(\frac{0.006 25}{1-(1+0.006 25)^{-6}})$

$P = \frac{8.125}{{1- {1.006 25}}^{-6}}$

$P = \frac{8.125}{1 - 0.9633}$

$P = \frac{8.125}{0.03669}$

P = $221.43

B. Total amount paid over six months

Paid = 6 × 221.43

Paid = $1328.58

C. Amount paid after four months

Paid = 4 × 221.43

Paid = $885.72

D. Balance owed after four months

Owed = 1328.58 - 885.72

Owed = 1341.14 – 1121.08

Owed = $442.86

E. Interest included in Payment 5

I = Pi

I = 442.86 × 0.006 25

I = $2.77

The interest included in Payment 5 is $2.77.

The ratio of Shauntay's cards to Jessica's cards is 5 to 3. After Shauntay gives Jessica 12 of her cards, both girls have the sa

Zepler [3.9K]

Answer:

They have 48 cards.

Step-by-step explanation:

let s be the number of Shauntay's cards and j be the number of Jessica's cards.

The ratio of Shauntay's cards to Jessica's cards is 5 to 3, then

(1) $\frac{s}{j}$ = $\frac{5}{3}$

After Shauntay gives Jessica 12 of her cards, both girls have the same number of cards, then

(2) s-12 =j+12.

From (2), we get s= j+24. If we put j+24 instead of s in (1) we get:

$\frac{j+24}{j}$ = $\frac{5}{3}$

3×j+24×3 = 5×j From this we get;

2×j=72 and j=36

After Shauntay gives Jessica 12 of her cards, Shauntay and Jessica would have 48 cards.
