Find point P that divides segment AB into a 2:3 ratio. The point should be closer to A. A(-3,1) and B(3,5). P = Answer Round you
torisob [31]

To solve this problem you must apply the proccedure shown below:

1. By definition, if the point P divides AB into a ratio a:b, this point is \frac{a}{a+b} of the distance of the segment. Therefore, this is:

\frac{a}{a+b} =\frac{2}{2+3} =\frac{2}{5}

2. The x coordinate of the point, is:

x1+\frac{a}{a+b} (x2-x1)=-3+\frac{2}{5}(3-(-3)) =-0.6

3. The y coordinate is:

y1+\frac{a}{a+b} (y2-y1)=1+\frac{2}{5} (5-1)=2.6

The answer is: P(-0.6, 2.6)

If you wash your car every 15 days &amp; I wash mine every 20 days, in how many days will we be washing them on the same day?
Nastasia [14]

Answer: 60 days

Step-by-step explanation:

To get the number of days that both of them will be washing the cars on thesame day, we have to find the lowest common multiple of 15 and 20. This will be:

Multiple of 15 = 15, 30, 45, 60, 75, 90

Multiples of 20 = 20, 40, 60, 80, 100

Lowest common multiple = 60

Therefore, they'll be Washing the car on thesame day on the 60th day.

How does the graph of g(x) = (x + 2)^3 − 7 compare to the parent function of f(x) = x^3
pickupchik [31]

Answer:

C

Step-by-step explanation:

The tricky part is always what is in the brackets with the x. It is highly anti intuitive.

(x + 2) moves the graph left, not right as you might think. So from this, only C and D can be considered as answers.

Since the 2 is with the x, that's how many units left you will go -- 2 units.

C is the only possible answer.

The - 7 tells you it will move 7 units down. The 7 with a minus acts the way you think it should. It goes down which is what normally happens on a graph. A mnus number outside the brackets means down.

"At ​$1.29 million​, they closed last month for...26 percent above what they paid in​ 2007." How much did they pay in​ 2007?
Morgarella [4.7K]

Answer:  Amount that they paid in 2007 is 1.01 millions.

Step-by-step explanation:

Since we have given that

Number of millions paid last month = $1.29 millions

According to question, it was 26% above what they paid in 2007.

Let the amount paid in 2007 be x

So, our equation becomes,

\frac{100+27}{100}\times x=1.29\\\\\frac{127}{100}\times x=1.29\\\\1.27\times x=1.29\\\\x=\frac{1.29}{1.27}\\\\x=1.01\ millions

Hence, Amount that they paid in 2007 is 1.01 millions.
