A, C, D, E

Step-by-step explanation:

We can make an equation with the information given using slope-intercept form [ y = mx + b ]. m = slope and b = y-intercept.

y = 4/7x - 9

Let's check to see which points are on the line.

(14, -1)

-1 = 4/7(14) - 9

-1 = 8 - 9

-1 = -1

TRUE

(1, 9)

9 = 4/7(1) - 9

9 = 4/7 - 9

9 = -8 3/7

FALSE

(0, -9)

-9 = 4/7(0) - 9

-9 = -9

TRUE

(21, 3)

3 = 4/7(21) - 9

3 = 12 - 9

3 = 3

TRUE

(7, -5)

-5 = 4/7(7) - 9

-5 = 4 - 9

-5 = -5

TRUE

(4, 7)

7 = 4/7(4) - 9

7 = 16/7 - 9

7 = -47/7

FALSE

Best of Luck!

What is the area of a triangle with vertices (1,0) (5,0) (3,4)

Aleksandr-060686 [28]

Answer:

The area of the triangle is of 8 units of area.

Step-by-step explanation:

Answer:

The area of the triangle is of 21 units of area.

Step-by-step explanation:

The area of a triangle with three vertices $(x_1,y_1),(x_2,y_2),(x_3,y_3)$ is given by the determinant of the following matrix:

$A = \pm 0.5 \left|\begin{array}{ccc}x_1&y_1&1\\x_2&y_2&1\\1_3&y_3&1\end{array}\right|$

In this question:

Vertices (1,0) (5,0) (3,4). So

$A = \pm 0.5 \left|\begin{array}{ccc}1&0&1\\5&0&1\\3&4&1\end{array}\right|$

$A = \pm 0.5(1*0*1+0*1*3+1*5*4-1*0*3-0*5*1-1*1*4)$

$A = \pm 0.5*(20-4)$

$A = \pm 0.5*16 = 8$

The area of the triangle is of 8 units of area.

Maxwell is taking out a loan for $8,750 for 2 years at an APR of 9.75%. What would be the finance charge to the nearest whole do

Sladkaya [172]

Answer:

Step-by-step explanation:

Using the formula for calculating simple interest

SI = principal × rate × time/100

Given

Principal = $8750

Rate = 9.75%

Time = 2years

Substitute

Interest = 8750×9.75×2/100

Interest = 87.59×19.5

Interest = 1,706.25

Hence the finance charge to the nearest whole dollar is $1706
