Answer:

J'(-15,10)\\\\K'(15,10)\\\\L'(0,-20)

Step-by-step explanation:

For this exercise you must remember that the original figure (before a transformation) is called "Pre-Image" and the one obtained after the transformation is called "Image".

 Dilation is defined as a transformation in which the Image and the Pre-Image have the same shape, but different sizes.

If a figure is dilated by a scale factor "k" with respect to the origin, the rule is:

(x,y) → (kx,ky)

In this case, the vertices of the triangle JKL (the Pre-Image) are:

J(-3.2)\\\\K(3,2)\\\\L(0,-4)

Knowing that the scale factor is:

k=5

You get that the vertices of the triangle J'K'L' (Image), are:

J'=(5(-3),5(2))=(-15,10)\\\\K'=(5(3),5(2))=(15,10)\\\\L'=(5(0),5(-4))=(0,-20)

A lawyer charges for her services based on the number of hours worked. The expression gives the total cost for h hours is 200h+2
zhannawk [14.2K]
H is the number of hours worked. So the expression 200h+250 is 200 times the number of hours plus 250.

Here's a few computations using different values for h

1 hour --> (200)(1)+250 = 450
2 hours --> (200)(2) + 250 = 650
3 hours --> (200)(3)+250 = 850
10 hours --> (200)(10)+250 = 2250

As you can see the 250 is fixed. It gets added to the cost no matter how many hours the lawyer works. This is most likely a flat fee. Just to meet the lawyer you pay $250.

The 200 gets multiplied by the hours worked. So the 200 is an hourly rate. The more hours the lawyer works, the more he gets paid because this part of the expression depends on the hours worked.

Thus, an interpretation of the expression 200h + 250 is that the lawyer charges a fee of $250 per consultation and an additional $200 per hour on top of that.

The triangle has side lengths 10cm, 24cm, and 28cm, is it a right triangle? Explain please i dont understand
Nitella [24]

In every right triangle, if you add up the squares of the two
shorter sides, you get the square of the longest side. If you
don't then it's not a right triangle.

10² = 100
24² = 576

100 + 576 = 676

676 is the square of 26. 
It's NOT the square of 28.

So 10 - 24 - 28 is not a right triangle.

Katena32 [7]

Answer:

3/12

Step-by-step explanation:

OR:

14 is equivalent to 3/12 because 1 x 12 is the same as 4 x 3. They both equal 12. 28 is equivalent to 3/12 because 2 x 12 is the same as 8 x 3. They both equal 24.

PLEASE HELP PICTRE SHOWN
matrenka [14]
First, you add 1 to both sides. Then square both sides to get rid of the square root. After that you just solve it like a normal equation when you are left with 4x-2=9.
