Answer:
1. y ax

A-------------------------------B

|__________________x ax
for this, your A might be (0,5), B (5,5), C (2,2).
parallel means railroad tracks: same slope, different intercepts.
line AB in this case has a slope of 0, intercept (0,5), so y₁=0x+5 or just y₁=5
the line passing through C also has slope 0, but intercept (0,2), so y₂=0x+2 or just y₂=2
2. perpendicular means that the slopes of two lines multiply out to -1. If line AB has, for example, a slope of 2/3, then the line passing through C would have slope -3/2 (negative reciprocal). To make things easier have either point A or B be on the x or y axis
khan academy has some helpful videos :)

Answer:
5120 cm^2
Step-by-step explanation:
Base area = (18 x 40)/2 = 360 cm^2
Base perimeter = 18 + 41 + 41 = 100 cm
LA = 100 x 44 = 4400 cm^2
surface area = 360 x 2 + 4400 = 5120 cm^2
Answer:
Step-by-step explanation:
9) 24=6(-x-3)
24=-6x-18
42=-6x
x=-7
10) 75=3(-6n-5)
75=-18n-15
90=-18n
n=-5
11) -3(1+6r)=14-r
-3-18r=14-r
17=-17r
r=-1
12) 6(6v+6)-5=1+6v
36v+36-5=1+6v
36v+31=1+6v
30=-30v
v=-1
13) -4k+2(5k-6)=-3k-39
-4k+10k-12=-3k-39
6k-12=-3k-39
9k=-27
k=-3
14) -16+5n=-7(-6+8n)+3
-16+5n=42-56n+3
-16+5n=45-56n
61=-61n
n=-1
