Answer:
y=-3x-1
Step-by-step explanation:
We can calculate the slope of this line:
Slope = (y2-y1)/(x2-x1) = (-4-2)/(1-(-1)) = -6/2 = -3
We can pretty much stop here and say B is correct.
Trapezoid Area =
[ ( Sum of the rules ) × ( height ) ] ÷ 2
_________________________________
Area = [ ( 6 + 12 ) × 8 ] ÷ 2
Area = [ 18 × 8 ] ÷ 2
Area = ( 18/2 ) × 8
Area = 9 × 8
Area = 72
Answer: F=140
Step-by-step explanation:
720=(x-60)+(x-40)+(x-20)+130+120+110
720-130-120-110=3x-120
360=3x-120
360+120=3x
480=3x
480/3=x
160=x
F=160-20
Next problem
102+31+x=180
133+x=180
x=180-133
x=47
