Step-by-step explanation:

The ratio of the two shorter legs of the top triangle is

$\dfrac{5}{4} = 1.25$

The bottom triangle has the following ratio:

$\dfrac{7.5}{6} = 1.25$

Since their ratios are the same, this means that the two triangles are similar.

Which is it? , 30 points

Answer:

It's choice B.

Step-by-step explanation:

Let's look the one you have chosen (A):

f(x) = x - 2/ 7 + 8

x-2 / 7 = f(x) - 8

x- 2 = 7(f(x) - 8)

x = 7(f(x) - 8) + 2

The inverse)= 7(x - 8) + 2

So it's not A.

B. f(x) = 5(x/4) - 3

5x / 4 = f(x) + 3

5x = 4(f(x) + 3)

x = 4(f(x) + 3 / 5

So the inverse is 4(x + 3) / 5

So it is B.
