Answer:

(-6, 6)

Step-by-step explanation:

The coordinates of B to start with is

(-2, 2)

To dilate this by a factor of 3....

-2 * 3 = -6

2 * 3 = 6

The new coordinates of B' would be

(-6, 6)

A few things to know:

- The number 3 is called a "scale factor"

- Dilation means we are multiplying all the (X, Y)'s by the scale factor

- If the scale factor is greater than 1, the size of the shape overall increases

- If the scale factor is less than 1, the size of the shape overall decreases

- If the scale factor is negative, the shape size stays the same. The shape just rotates 180 degrees and moves to the opposite quadrant.

Michelle is building a rectangular landing strip for airplanes .She has material to cover 1/1,500 of a square mile. The landing

ANEK [815]

I think that the missing word here is:
"with the amount of the material that Michelle has"

Let's say that her landing strip is x miles long, then its area would be:

$\frac{1}{6} *x$

We also know how big it is:

$\frac{1}{6} *x= \frac{1}{1 500}$

now, let's multiply both sides by 6:
$\frac{6}{6} *x= \frac{6}{1 500}$
$1 *x= \frac{3}{750}$
$x= \frac{1}{250}$

So the answer is that it would be $x= \frac{1}{250}$ miles wide

Ms. Chen is planning to take her camp group on a field trip to Pottery Bayou where each person will create her own piece of art

erica [24]

Answer:

1. $C=21x.$

2. $C=(8x+104).$

Step-by-step explanation:

Let the number of people in the group be x. Denote the total cost as C.

1. If the regular cost is $21 per person, then the total regular cost for x people is $C=21x.$

2. If the special cost is $8 per person, then the total special cost for x people is $\$8x.$ There is an additional $104 fee for a private room, thus the total special cost is $C=(8x+104).$

PLEASE HELP What is the equation of the line shown?

Ivenika [448]

So, let's start off with explaining what these different questions mean;

y = |x + c| Shifts the graph c units left.

y = |x - c| Shifts the graph c units right.

y = |x| + c Shifts the graph c units up.

y = |x| - c Shifts the graph c units down.

(0,0) Is the starting point on any graph like this. So, determine the answer by going through the list of answers.

I believe the answer is y = 2x.

I would like to know if I am wrong so contact me!!
