Please help me answer this last question. The function shown describes f(x), the cost (in hundreds of thousands of dollars) of making x bicycles (in thousands).

f(x)= 1.25 + 0.35x
B. What is the cost to make 4,000 bicycles? Show your work.

1401.25

Step-by-step explanation:

F(4000)= 1.25+0.35(4000) = 1401.25

f

step-by-step explanation:

f

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.
