Equation of a line in general form with a point (-3,0)

The equation of the line that has slope m and passes through point (x1, y1) is

y - y1 = m(x - x1)

You have point (-3, 0), so x1 = -3, and y1 = 0.

y - 0 = m(x - (-3))

y = m(x + 3)

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

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.
