Sketch the linear function f(x) = 2/3(3x + 1) − 6x. which key feature of the graph is true?
a) y-intercept (0,-4)
b) x-intercept (2/3,0)
c) x-intercept (1/6,0)
d) y-intercept (0,-1/3)

Step-by-step explanation:

To find the right answer, we can find both axis interceptions.

The given function is

We can rewrite this function

So, x-intercept is when f(x) = 0

This means that x-intercept points is (1/6, 0).

y-intercept is when x = 0

y-intercept point is (0, 2/3).

the right choice is C) x-intercept (1/6,0).

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

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.
