Step-by-step explanation:
line 1 and 2 : parallel
as line 2 is actually
6x + 2y = 8
2y = -6x + 8
y = -3x + 4
so, they have the same slope (factor of x).
line 1 and 3 : neither
the slopes -3 and 3 are not parallel not perpendicular (90°).
line 2 and 3 : neither
as line 2 is parallel to line 1, it has the same relationship to line 3 as line 1.
100 pages a hour
This is a fraction equal to
300 Pages ÷ 3 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 3
300 Pages ÷ 3
3 hours ÷ 3
=
100 Pages
1 hour
=
100 Pages
hour
= 100 Pages per hour
Answer: B
Step-by-step explanation:
The ratio of the areas of similar figures is the square of the scale factor.
- Scale factor = image/preimage = 48/12 = 4.
So, the ratio of the areas is 16, and thus the area of DEF is (16)(90)=1440
