<em>Answer: </em>

Her weekly allowance is $10

<em>Step-by-step explanation: </em>

<em>Let's call x her weekly allowance </em>

<em> </em>

<em>At the end she has $12. She obtained this for the addition of the money she earned cleaning windows ($7) and the half of her weekly allowance (the other half she spend it at the movies). Mathematically: </em>

<em> </em>

<em>x/2 + 7 = 12 </em>

<em> </em>

<em>Solving for x: </em>

<em> </em>

<em>x/2 = 12 - 7 </em>

<em> </em>

<em>x = 2*5 </em>

<em> </em>

<em>x = $10</em>

So all you have to do is take the first numbers of each multiple and multiply them. 
1 x 2 x 3 x 4 = 24 
Now you just add the 4 zeros to your answer.

Our answer even checks!

A line segment has endpoints P(-1,5)and Q(5,2) find the coordinate of that trisect the segment​
musickatia [10]

Answer:

(1, 6).  The second is (-1 + 2 + 2, 1 + 1 + 1), or (3, 3)

Step-by-step explanation:

Moving from P to Q, we see that x increases by 6  and y increases by 3.

"Trisect" means "divide into three equal subintervals."

We find (1/3) of 6 (which comes out to 2) and (1/3) of 3 (which comes out to 1).  

Thus, the first junction (between 1st and 2nd trisection) is (-1 + 2, 5 + 1), or (1, 6).  The second is (-1 + 2 + 2, 1 + 1 + 1), or (3, 3)

Sergeu [11.5K]

Answer:

I think the answer is y = 3x + 12.

Step-by-step explanation:

y = 3 (x - 1) (x - 4)

y = 3x -3 (x - 4)

y = 3x + 12
