The line passing through the points (-2, 10) and (5, -11)

Answers

Answer:

y-intercept = (0, 4)

x-intercept = (3/4, 0)

Step-by-step explanation:

1 - Find the slope

[tex]slope = m = \frac{rise}{run} = \frac{y_2~-~y_1}{x_2~-~x_1} = \frac {-11-10}{5-(-2)} = \frac {-21}{7} = -3[/tex]

2 - Plug the slope into y = mx + b and substitute a point into x and y to find the y-intercept, b, by isolating it.

y = mx + b

y = -3x + b

10 = (-3)(-2) + b

10 = 6 + b

-6   -6

4 = b

y-intercept = (0, 4)

3 - Rewrite the completed formula

y = -3x + 4

4 - Substitute 0 in for y to find the x-intercept

0 = -3x + 4

-4          - 4

-4 = -3x

-4/-3 = -3x/-3

 4/3 = x

x-intercept = (4/3, 0)

A person places $7420 in an investment account earning an annual rate of 5.9%, compounded continuously. Using the formula V = Pe^{rt}V=Pe rt , where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 20 years.

Answers

Answer:

$24147.50

Step-by-step explanation:

Step one:

given

principal=$7420

rate = 5.9%= 0.059

time = 20years

Step two:

Required

Final amount V

using the relation

[tex]V = Pe^{rt}[/tex]

Substituting we have

[tex]V = 7420e^{0.059*20}\\\\V=7420e^{1.18}\\\\V=7420*3.2543\\\\V=24147.456[/tex]

To the nearest cent

= $24147.50

The amount of money in the account after 20 years is $24147.50

A runner saved $25 when he purchased a pair of tennis shoes on sale. If the sale price was 35% off the regular price, what was the regular price of the tennis shoes?

Answers

Given:

Amount saved in sale = $25

Sale price was 35% off the regular price.

To find:

The regular price of the tennis shoes.

Solution:

Let the regular price of the tennis shoes be x.

Sale price was 35% off the regular price.

[tex]Discount=\dfrac{35}{100}x[/tex]

Amount saved in sale = $25

[tex]0.35x=25[/tex]

Divide both sides by 0.35.

[tex]x=\dfrac{25}{0.35}[/tex]

[tex]x=71.42857[/tex]

[tex]x\approx 71.43[/tex]

Therefore, the regular price of the tennis shoes is $71.43.

need help finding the slope line through each pair ​

Answers

Answer:

9) -25/21

11) 14

Step-by-step explanation:

In each case, subtract the y-coordinates. Subtract the x-coordinates in the same order. Divide the difference in y by the difference in x.

9)

y-coordinates: -10 - 15 = -25

x-coordinates = 6 - (-15) = 21

slope = (difference in y)/(difference in x) = -25/21

11)

y-coordinates: -20 - 8 = -28

x-coordinates = 3 - 5 = -2

slope = (difference in y)/(difference in x) = -28/(-2) = 14
