(-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.

Find the y-intercept using the formula [ y = mx + b ].

y = 1/3x + b

-12 = 1/3(-24) + b

-12 = -8 + b

-4 = b

Use (18, 2) to see if the line passes through it

y = 1/3x - 4

2 = 1/3(18) - 4

2 = 6 - 4

2 = 2 TRUE

Thus, the line does pass through (18, 2).

Best of Luck!

the line does not pass trough the point (18, 2) that other line decreases and for it to passes through the point it would have to increases

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?

Answers

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.

-x + 5 < 7
Which of the following values of x DO NOT make the inequality true?
A. -1
B.- 3
C. 7
D. 5

Answers

Answer:

B: -3

Step-by-step explanation:

-(-3) + 5 < 7

3 + 5 <7

8 < 7 FALSE

Answer:

-3

Step-by-step explanation:

Solve for x in the inequality, to get x > -2 (see the image below if you want to know how to solve it). Then, we can substitute the numbers for x to see which ones DO NOT make the inequality true:

-1 > -2  This is true, because -1 is greater than -2

-3 > -2  This is false, because -3 is not greater than -2

7 > -2  This is true, because 7 is greater than -2

5 > -2  This is true, because 5 is greater than -2

So you can see that -3 is the number that DOES NOT make the inequality true. So therefore:
