The scale factor from S to M is 3/2 What is the scale factor from M to S
natita [175]

we conclude that if the scale factor from S to M is 3/2, then the scale factor from M to S is 2/4.

<h3></h3><h3>What is the scale factor from M to S?</h3>

Suppose we have a figure S. If we apply a stretch of scale factor K to our figure S, we can say that all the dimensions of figure S are multiplied by K.

So, if S represents the length of a bar, then after the stretch we will get a bar of length M, such that:

M = S*K

If that scale factor is 3/2, then we have the case of the problem:

M = (3/2)*S

We can isolate S in the above relation:

(2/3)*M = S

Now we have an equation (similar to the first one) that says that the scale factor from M to S is 2/3.

Then we conclude that if the scale factor from S to M is 3/2, then the scale factor from M to S is 2/4.

Which of the following expressions is the inverse of the function y equals quantity x minus 2 divided by 3?
Natalija [7]
Y = (x - 2)/3
3y = x - 2
x = 3y + 2

Therefore, the inverse of y = (x - 2)/3 is y = 3x + 2

Help me find x please
Sedaia [141]

Answer:

\displaystyle 13 = x

Step-by-step explanation:

All three angles in an equilateral triangle are equivalent, and they sum up to 180°, so each angle measures 60°:

60° = [8x - 44]°

+ 44° + 44°

____________

\displaystyle \frac{104°}{8} = \frac{[8x]°}{8} \\ \\ 13° = x

I am joyous to assist you anytime.
