Samuel wants to create a password containing one, two, or three lowercase vowels followed by two digits. How many different passwords are possible? (Note: assume the letters "a", "e", "i", "o", and "u" are the vowels of the English alphabet).

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
