Answer:

y = 8/5x - 3

Step-by-step explanation:

First, find the slope using rise over run (y2 - y1) / (x2 - x1)

(y2 - y1) / (x2 - x1)

(-19 - 5) / (-10 - 5)

-24 / -15

= 8/5

Plug in the slope and a given point into y = mx + b, and solve for b

y = mx + b

5 = 8/5(5) + b

5 = 8 + b

-3 = b

Plug in the slope and b into y = mx + b

y = 8/5x - 3

So, the equation is y = 8/5x - 3

One month, Ruby worked 6 hours more than Isaac, and Svetlana worked 4 times as many hours as Ruby. Together they worked 126 hour

Paladinen [302]

Answer/Step-by-step explanation:

Let x hours be the number of hours Issac worked

x+6 hours be the number of hours Ruby worked

4(x+6) hours be the number of hours Svetlana worked.

x + x + 6 + 4(x+6) = 126

x + x + 6 + 4x +24 = 126

6x +30 = 126

6x = 96

x = 16

Therefore, Issac worked 16 hours.

Ruby worked 16+6 = 22 hours

Svetlana worked 22 × 4 = 88 hours.

A cash register contains only five dollar and ten dollar bills. It contains twice as many five's as ten's and the total amount o

Effectus [21]

Answer:

Step-by-step explanation:

Let number of ten dollar bills be x .

So, number of five dollar bills = 2 x

Total amount of money in the cash register = 620 dollars

Amount of money in total cash as a result of five dollar bills = 2 x × 5 = 10 x dollars

Amount of money in total cash as a result of ten dollar bills = x × 10 = 10 x dollars

According to question ,

Total amount of money in the cash register = Amount of money in total cash as a result of five dollar bills + Amount of money in total cash as a result of ten dollar bills

⇒ 620 = 10 x + 10 x

⇒ 620 = 20 x

⇒ x = $\frac{620}{20}$ = 31

So, number of ten dollar bills = 31
