What is the equation of the line in standard from ?

Y = 11/7x - 25/7

Step-by-step explanation:

4,2 -3,-9

-9 - 2 / -3 - 4 = -11 / -7 or 11/7

2 = 11/7(4) + b

2 = 39/7 + b

14/7-39/7 = b

B = -25/7

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

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.
