The table represents the function f(x) = 5x. Which value goes in the empty cell?

TABLE: - - - - ANSWER CHOICES:

-1 N/A - - a. -51

0 0 -- - - - b.-5

1 5 - - - c.5

2 10 - - - - d.51

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2

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.
