(-1, 0), (0, -4), (1, -6) points are solutions of the given quadratic equation.
What is a quadratic equation?A quadratic equation is an equation where the variable has the highest power of 2.
Given equation is y = x² - 3x - 4
1. For (-4, 0), L.H.S = 0, R.HS = (- 4)² - 3(- 4) - 4 = 24.
Hence, (-4, 0) is not a solution of the given equation.
2. For (-1, 0), L.H.S = 0, R.HS = (- 1)² - 3(- 1) - 4 = 0.
Hence, (-1, 0) is a solution of the given equation.
3. For (0, -4), L.H.S = -4, R.HS = (0)² - 3( 0) - 4 = - 4
Hence, (0, -4) is a solution of the given equation.
4. For (1, -6), L.H.S = -6, R.HS = (1)² - 3(1) - 4 = -6.
Hence, (1, -6) is a solution of the given equation.
5. For (1, 0), L.H.S = 0, R.HS = (1)² - 3(1) - 4 = -6.
Hence, (1, 0) is not a solution of the given equation.
6. For (3, -7), L.H.S = -7, R.HS = (3)² - 3(3) - 4 = -4.
Hence, (3, -7) is not a solution of the given equation.

Annika's older cousin borrowed $800 to repair her car. she will pay off the loan after 2 years by paying back the principal plus 4.5% simple interest each year. How much will she spend in interest? How much will she pay back altogether?
Answer:
The equation below is provided:
$800 = principal amount borrowed/loaned
4.5% = interest per year
2 years = terms of payment
You need to know how much is the interest per year.
$800 * 4.5% = $36
Then, multiply the amount to the terms of payment to know the total amount of the interest to be paid.
$36 * 2 years = $72
The correct answer for the amount that Anika will spend for the interest is $72.

9514 1404 393
Answer:
37.5% decrease

= (50 -80)/80 × 100%
= -3/8 × 100% = -37.5%
The negative sign indicates a decrease.
The decrease in price is 37.5%.
