Jack works after school. Each day he is paid a set amount, plus an hourly wage. Hours11.522.53
Pay 18 23283338

Which is a reasonable domain for the function f(x) = 10x + 8?
A.0 < x < 6
B.0 < x < 24
C.0 < x < 68
D.0 < x < 248

The correct option is;

A. 0 < x < 6

Step-by-step explanation:

The given data indicates how much Jack is paid on hourly wage is presented here as follows;

Hours             Pay

1                         18

1.5                     23

2                        28

2.5                     33

3                         38

Given that the domain is the number of hours worked by Jack after school, and that he receives a set amount at all values of the number of hours worked, a reasonable domain is from 0, at which the pay is 8, to 6 which is less than the normal 8 hours a day job, as he works part time.

Therefore, the correct option is;

A. 0 < x < 6.

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.
