20 Points!
I'm Really confused on this please help.
Write three points (x, y) that exist on the line.
Answers
Answer:
3 points on the line - (.5,3) (1,2) (1.5,1)
Step-by-step explanation:
y = -2x + 4 (1.5,1)
1 = -2x + 4 subtract 4 from each side
-3 = -2x divide each side by -2
1.5 = x
y = -2x + 4 (1,2)
2 = -2x + 4 subtract 4 from each side
-2 = -2x divide each side by -2
1 = x
y = -2x + 4 (.5,3)
3 = -2x + 4 subtract 4 from each side
-1 = -2x divide each side by -2
.5 = x
Answer:
(1,2) (2,0) (3,-2)
Step-by-step explanation:
What I did to get those is plug in the numbers 1, 2, and 3 as values of X.
-2(1)+4
that gave me 2 as the Y value and now we have the coordinate (1,2).
-2(2)+4
that gave me 0 as the Y value and now we have the coordinate (2,0).
-2(3)+4
that gave me -2 as the Y value and now we have the coordinate (3,-2).
hope this helps.

When a person 6 feet tall casts a shadow
10 feet long, how tall is a nearby tree
which casts a shadow of 45 feet?
Answers
Answer:
75 feet
Step-by-step explanation:
Answer:
27
Step-by-step explanation:
Proportion
6 feet man/10 feet shadow = x (tree) / 45 feet (shadow)

10x = 45*6
10x = 270
x = 270/10

1) Given that the measure of Angle 2 = 115 degrees and the measure of Angle 8 = 115 degrees, is line m parallel to line p?
Answers
Answer:
YES
Step-by-step explanation:
When a transversal cuts two parallel lines, the alternate interior angles are congruent. So, for two lines to be parallel, their alternate interior angles has to be equal.
Angle 2 and angle 8 are alternate interior angles. They both measure 115°. Since these alternate interior angles are congruent, therefore, line m is parallel to line p.
