Answer:

5x + y - 4 = 0

Step-by-step explanation:

When we are given two points and are asked to find the equation of the line we use the two - point form.

Two - point form: $ \frac{y - y_1}{y_2 - y_1} = \frac{x - x_1}{x_2 - x_1} $.

where: $ (x_1,y_1) $ and $ (x_2,y_2) $ are the two points on the line.

Given the two points are: (5,21) and (-5,-29).

Substituting in the two point form:

⇒  $ \frac{y - 21}{-29 - 21} = \frac{x - 5}{-5 -5} $

$ \implies \frac{y - 21}{-50} = \frac{x - 5}{-10} $

$ \implies y - 21 = 5x - 25 $

⇒                              5x + y - 4 = 0

Paraphin [41]

Answer:

Mandy will take 67.5 mins to complete the 15 km race.

Step-by-step explanation:

Given:

Mandy runs 4 km in 18 min

She plans to run in a 15 km race.

We need to find how much time required to run 15 km.

4 km =18 min

15 km = time required for 15 km race

By Using Unitary method we get,

Time required for 15 km = \frac{18\times 15}{4}=67.5 mins

Hence time required by Mandy to complete 15 km race is 67.5 mins.

Elbert used to make $22 an hour, but got a 10% raise. How much more will he make in 40 hours work week with the raise
creativ13 [48]

Answer:

Elbert will Make $968 in 40 hours of work with the raise.

Step-by-step explanation:

Given:

Elbert makes $22 an hour.

He got 10% raise

Money raised on 10% = \frac{10}{100}\times 22=\$2.2

Now total money for per hour after raise  = \$22+\$2.2=\$24.2

Now to find the total money earned after 40 hours with raise we need to multiply total money for per hour after raise with number of hours.

Total money earned = \$24.2 \times 40 = \$968

Hence, Elbert will Make $968 in 40 hours of work with the raise.
