Find the range of the graphed function. 10 O A. y is all real numbers O B. -10≤y≤0 O C. -6≤ y≤9 O D. y≤0​

the answer is b

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

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.
