Answer:

<h3>A , D</h3>

Step-by-step explanation:

Check the inequality for each point.

For A. (-3,2)

y <  {2x}^{2}  + 3x - 5 \\ 2  <  {2 ( - 3)}^{2}  + 3( - 3) - 5 \\ 2 < 2 \times 9 - 9 - 5 \\ 2 < 18 - 9 - 5 \\ 2 < 4 \\

The inequality is satisfied.

For B. (-2,9)

y <  {2x}^{2}  + 3x - 5 \\ 9 < 2 {( - 2)}^{2}  + 3( - 2) - 5 \\ 9 < 2(4) - 6 - 5 \\ 9 < 8 - 6 - 5 \\ 9 <  - 3 \\

The inequality is not satisfied.

For C. (1,6)

y <  {2x}^{2}  + 3x - 5 \\ 6 <  {2(1)}^{2}  + 3(1) - 5 \\ 6 < 2(1) + 3 - 5 \\ 6 < 2 + 3 - 5 \\ 6 < 0

The inequality is not satisfied.

For D. (3,1)

y <  {2x}^{2}  + 3x - 5 \\ 1 <  {2(3)}^{2}  + 3(3) - 5 \\ 1 < 2(9) + 9 - 5 \\ 1 < 18 + 9 - 5 \\ 1 < 22 \\

The inequality is satisfied.

For E. (-1,5)

y <  {2x}^{2}  + 3x - 5 \\ 5 <  {2( - 1)}^{2}  + 3( - 1) - 5 \\ 5 < 2(1) - 3 - 5 \\ 5 < 2 - 3 - 5 \\ 5 <  - 6 \\

The inequality is not satisfied.

1. Elissa is buying a new car. She has an excellent credit score of
k0ka [10]

Answer:

$273.38 per month

Step-by-step explanation:

<u>Monthly Payment Formula</u>

\sf PMT=\dfrac{Pi(1+i)^n}{(1+i)^n-1}

where:

  • PMT = monthly payment
  • P = loan amount
  • i = interest rate per month (in decimal form)
  • n = term of the loan (in months)

Given:

  • P = $19,500 - $4,000 = $15,500
  • i = 2.25% / 12 = 0.0225 / 12
  • n = 5 years = 60 months

\implies \sf PMT=\dfrac{15500 (\frac{0.0225}{12})(1+\frac{0.0225}{12})^{60}}{(1+\frac{0.0225}{12})^{60}-1}

\implies \sf PMT=273.3788438

\implies \sf PMT=\$273.38
