Answer:

y = 1/3(x-5)

Step-by-step explanation:

To find the inverse of a function switch the x and y and then solve for y.

x = 3y + 5

x-5 = 3y

(x-5)/3 = y

y = 1/3(x-5)

If BCD ~ GEF, find BD

Masja [62]

Answer:

Step-by-step explanation:

if the triangles are similar then EG/BC = FG/BD

51/(x+4) = 57/(2x-7) cross multiply expressions

102x - 357 = 57x + 228

102x - 57x = 228 + 357

45x = 585 divide both sides by 45

x = 13

BD = 2x -7 and 13×2 - 7 = 19

Answer:

181 units²

Step-by-step explanation:

Let's break up the polygon into 3 shapes

Step 1: Area of the left rectangle

4(7) = 28 units²

Step 2: Area of middle rectangle

9(13) = 117 units²

Step 3: Area of top square

6² = 36 units²

Step 4: Add them all up

28 + 117 + 36 = 181 units²
