Why is it important that everyone follow the same order of operations when evaluating expressions?

Because if not, different people would get different answers. If the expression is evaluated without using the order of operations, the answer won’t be the same. I hope this helps!

As an example, let’s say we had 3+4x2
Without PEMDAS, we would add 3 and 4, then multiply by 2, getting 14 (the wrong answer).
With PEMDAS, we would multiply 4 and 2, then add 3, getting 11 (the correct answer!).
So if you don’t use PEMDAS, you’ll just get a different answer than you should’ve. Hope that helped!

Given a dilation around the origin, what is the scale factor K?<br><br> Do, K = (20,16) → (-5,-4)
Rudik [331]

Answer:

Scale factor, K = -1/4

Step-by-step explanation:

Dilation of any image changes its size and the shape remains same.

The scale factor is the ratio of dilated image to original image.

Dilation rule: (x, y) → (kx, ky), where k is the scale factor.

It means k = x₂/x₁ or y₂/y₁

K = -5/20 = -1/4 or K = -4/16 = -1/4.

<u>The negative value of scale factor (K) indicates dilations with 180 degree rotation of the dilated image.</u>

Hence the scale factor is K = -1/4.
