Niall owes $187 to his cousin. However, he doesn't have any money right now. He hopes to earn some money by painting a house. He

gets paid $34 for every 2 hours he paints. Which equation of a line models y, the amount of money he will have after paying back his cousin, in terms of x, the number of hours he spends painting?

Answer:

y=17x-187 where x>11

Step-by-step explanation:

Niall gets $34 for 2 hours.

So, he gets 34/2=17 dollars per hour.

Now, he owes $187 to his cousin.

Let the number of hours he works be = x

Let the money left with him after paying his cousin be = y

So, the equation forms:

y=17x-187

Rather we can say it is :

y=17x-187 where x>11

If we want to know how many hours are needed to pay the debt, we can consider y = 0

17x-187=0

17x=187

x=187/17

So, x = 11 hours

So, Niall needs 11 hours of work to pay back his cousin and after that all his earnings is 'y'. When x>11 then 'y' will have some money left.

The equation you would write would be:
2x+34=187<span />

Vera_Pavlovna [14]

Answer:

<em>About 900 cans not stamped in 3 hours</em>

Step-by-step explanation:

<u>Proportions</u>

Sally found that 150 cans were not stamped in the 1/2 hour trial run.

Following the same proportion in time, we can say:

150 cans not stamped in 1/2 hour. Multiplying by 2:

300 cans not stamped in 1 hour. Multiplying by 3:

900 cans not stamped in 3 hours

About 900 cans not stamped in 3 hours

Simplify the expression
NeTakaya

First, solve the parenthesis

Remember to follow PEMDAS, and the left-> right rule

12/3 = 4

4 x 2 = 8

8 + 3 = 11

11 - 7 = 4

Square the remaining number

4² = 4 x 4 = 16

16 is your answer

hope this helps

Someone help?!.........
koban [17]
Answer: y = -2x + 16

Explanation:

Use point slope form:

(y1 - y) = m(x1 - x)

y1 = 6 and x1 = 5 and m = -2

6 - y = -2(5 - x)
6 - y = -10 + 2x
-y = 2x - 10 - 6
-y = 2x - 16
y = -2x + 16
