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?

The equation would be 34 x 2x-187= y.

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

He 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.

1. Which expression is equivalent to the given expression? * -0.25 (84 – 32n) - n
Ira Lisetskai [31]
Hi! Multiply -0.25 by the inner numbers.

-0.25 times 84 = 21
-0.25 times -32n = -8n

Then take the -n and add that
21 -8n - n

-8n - n (or -1n) = -9n

therefore, answer would be a) 21 - 9n

Given the coordinate transformation f(x, y) = (- 2x, y) and the domain (0, 5), (8, - 1) and (- 6, 4) what is the range?
Mariana [72]

Answer:

{(0, 5), (-16, -1), (12, 4)}

Step-by-step explanation:

Given the coordinate transformation f(x, y) = (- 2x, y) and the domain (0, 5), (8, - 1) and (- 6, 4), to get the range, we will get f(x, y) for all the domain values

For the coordinate (0,5);

f(0, 5) = (-2(0), 5)

f(0, 5) = (0, 5)

For the coordinate (8, -1);

f(8, -1) = (-2(8), -1)

f(8, -1) = (-16, -1)

For the coordinate (-6, 4);

f(-6, 4) = (-2(-6), 4)

f(0, 5) = (12, 4)

Hence the range is {(0, 5), (-16, -1), (12, 4)}

Only the circled ones
ozzi
2.

M must be (0,0) since it coincides with the origin
R must be (a+b, √(a²-b²)).
The x-coordinate is b from A translated to the right by a.
The y-coordinate is the same as A.

(I think the square root is there to confuse you).

3.

R(0,0)
C(a,b) (same x as T, same Y as E)

5.

Not sure how to prove that.

Help please!!! A bag contains 50 marbles, 10 of which are blue, 8 are red, 20 are green, and 12 are purple. Marcie takes a marbl
Andru [333]

Answer:

A


Step-by-step explanation:

We would need to multiply the number of trials (which is 500) by the probability of choosing a red in 1 try from the information given.


<em>There are 50 in total, and 8 of them are red, so:</em>

P(red) = \frac{8}{50}=0.16


<em>Now we multiply this with 500 to get:</em>

500*0.16=80


The correct answer is A.
