M=(6-1)/(8-5)=5/3
y=5x/3+b, using (5,1)
1=25/3+b
b=-22/3
y=(5x-22)/3
...
m=(8-3)/(-1--4)=5/3...
y=5x/3+b, using (-1,8)
8=-5/3+b
b=29/3
y=(5x+29)/3
Since they have the same slope and difference y-intercepts they are parallel lines and will never intersect.
Answer: XI = 10.35 mm
Step-by-step explanation:
Considering the given triangle XIF, to determine XI, we would apply the sine rule. It is expressed as
a/SinA = b/SinB = c/SinC
Where a, b and c are the length of each side of the triangle and angle A, Angle B and angle C are the corresponding angles of the triangle. Likening it to the given triangle, the expression becomes
XI/SinF = XF/SinI = FI/SinX
The sum of the angles in a triangle is 180°. It means that
F + 63 + 52 = 180
F = 180 - (63 + 52)
F = 65°
Therefore
XI/Sin 65 = 9/Sin 52
Cross multiplying, it becomes
XISin52 = 9Sin65
0.788XI = 9 × 0.906
0.788XI = 8.154
XI = 8.154/0.788
XI = 10.35
Answer:
(-4,0)
Step-by-step explanation:
We start at the origin (where the lines cross)
We will go left 4 units. That is the x coordinate (-4)
We go up 0. That is the y coordinate
(x,y)
C = (-4,0)
I think the answer was a option c
Step-by-step explanation:
one would have to measure the sides, but from the looks of it, yes, A'B'C'D' is a dilation from ABCD. all sides of the new shadow appear to be parallel to the sides of the original shape. and it appears that the scaling factor is the same for all 4 sides (but again, one would have to measure precisely).
