= -28x -7

7. 7 (-v-7)

= - 7v - 49

8. 7 ( 2 - x )

7 (- x + 2 )

= - 7 x + 14

9. 4 ( - 7 - x )

4 ( - x - 7)

= -4 x -28

10. 5 ( k - 5 )

5k - 25

Solve for k. 9/2k-3=4/k+1

Ivenika [448]

You'll need to use parentheses here to convey this problem accurately to possible helpers. Unsure of whether you mean (9/2)k -3 or 9 / (2k-3).

I will assume that you mean:

9 4
------- = ---------
2k-3 k+1

Cross mult: 9k+9=8k-12, so k= -21.

If that's not what you expected, then try again to present the problem without ambiguities.

Danny bought a new year. The total amount she needs to borrow is $19,541. She plans to take out a six-year loan at an APR of 8.3

lys-0071 [83]

Present value of loan, P = 19541
monthly interest rate, i = 8.3%/12
repayment period = 6 years = 72 months

Monthly payment,
$A=\frac{P(i*(1+i)^n)}{(1+i)^n-1}$
$=\frac{19541(.083/12*(1+.083/12)^{72})}{(1+.083/12)^{72}-1}$
$=345.487$
$=345.49$ to the nearest cent
