Thats my question down there mates

Law Incorporation [45]

Answer:

x = 9

Step-by-step explanation:

A line segment parallel to a side of a triangle and intersecting the other 2 sides divides the 2 sides in proportion, that is

$\frac{9}{72}$ = $\frac{1}{8}$ = $\frac{3x-20}{56}$ ( cross- multiply )

8(3x - 20) = 56

24x - 160 = 56 ( add 160 to both sides )

24x = 216 ( divide both sides by 24 )

x = 9

Lines

kirill [66]

Answer:

line r: y=-2x-2

line s: -2x+1

lime t: -2x+3

Step-by-step explanation:

every slope must be -2 since that's stated in the question

to find b in y=mx+b, you substitute 0 for x and the y coordinate when x is 0 into the equation (for example for slope r, when x is 0 then y is -2, so -2=-2(0)+b) then solve for b (-2=-2(0)+b is -2=b)

basically, b is the y component when x is 0
