Which of the following coordinate points represents the x-intercept of the equation 2x + 3y = 10? A. (5, 0)
B. (0, 0)
C. (–4, 0)
D. (–2, 0)

A

Step-by-step explanation:

take out the 'y' and the equation is left to 2x=10 and you divide 2x and 10 by 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.
