Which transformation of y = f(x) moves the graph 7 units to the left and 3 units down? a) y = f(x + 7) - 3
b) y = f(x - 7) - 3
c) y = f(x + 7) + 3
d) y = f(x - 7) + 3
Can someone please explain how they got the answer? thank you :)

Given the two similar triangles, how do i find the missing length? if a=4, b=5, and b'=7.5 find a'

Find two consexutive odd integers such that the sum of their square is 650

Prove the converse of the pythagorean theorem using similar triangles. the converse of the pythagorean theorem states that when the sum of the squares of the lengths of the legs of the triangle equals the squares length of the hypotenuse, the triangle is a right triangle. be sure to create and name the appropriate geometric figures.
