How do I find a change in scale factors? I forgot to write notes on how to find a change in scale factors and can’t seem to find

a video. A formula and/or explanation would be absolutely wonderful! Or, a video recommendation from someone who explains it would do as well. :) This is for a seventh-grade level question.

Answer:

In two similar geometric figures, the ratio of their corresponding sides is called the scale factor.

To find the scale factor,we need to follow some rules:

locate two corresponding sides, one on each figure.

Write the ratio of one length to the other to find the scale factor from one figure to the other

-2x - y = -9<br><br>5x -2y = 18<br>Solve as a whole number
nexus9112 [7]

Answer:

x = 4, y = 1

(4, 1)

Step-by-step explanation:

-2x - y = -9

5x -2y = 18

-2x - y = -9

+2x     +2x

-y = 2x - 9

/-1    /-1

y = -2x + 9

5x -2y = 18

5x - 2(-2x + 9) = 18

5x + 4x - 18 = 18

9x - 18 = 18

    + 18   + 18

9x = 36

/9  /9

x = 4

Now, we solve for y:

-2(4) - y = -9

-8 - y = -9

+ 8     +8

-y = -1

/-1  /-1

y = 1

(x, y) -> (4, 1)

Hope this helps!

Get the variable alone, so add the one to both sides.
s=10+1.
Next simplify.

The x^k term will be ...

  (6Ck)(x^k)(4^(6-k))

For k=4, this is ...

  (6C4)(x^4)(4^2) = 15·16·x^4 = 240x^4

The coefficient of x^4 is 240.

_____
