81a^2+16b^2
Step-by-step explanation:
Answer:
The correct answer is neither.
Step-by-step explanation:
To find the relationship between the lines, find the slope of each. You can do this by using the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (4 - 1)/(4 - -8)
m = 3/12
m = 1/4
Now do so for the second line.
m(slope) = (y2 - y1)/(x2 - x1)
m = (-3 - -7)/(9 - -9)
m = 4/18
m = 2/9
Since they are not the same and not opposite/reciprocal, then we know they are neither parallel nor perpendicular.
1) Parallel lines have equal slopes.
We need to find the slope of the given line by solving for y.
5x - 15y = 30
-15y = -5x + 30
y = (1/3)x - 2
The slope of the given line is 1/3, so the slope of the parallel line is also 1/3.
2) Line 1 has slope 2/3.
Line 2 has slope 2/3.
3) Line 1 is a vertical line through x = 2. Line 2 is a horizontal line through y = -5. The lines are perpendicular.
4) The given line can is solved for y, so we can see its slope is -5/2. The slopes of perpendicular lines are negative reciprocals. The perpendicular line has slope 2/5. We have point (5, 0) which is (x1, y1) in the slope-point formula.
y - 0 = (2/5)(x - 5)
y = 2/5 x - 2
5) The given equation has slope -3. To find the negative reciprocal, write the slope as a fraction, flip it, and change the sign.
Slope of perpendicular line is 1/3.
Answer:
The answer to your question is below
Step-by-step explanation:
1.- 3x + 54 = 5x + 14
3x - 5x = 14 - 54
-2x = - 40
x = 20
2.- I can not see it
3.- Yes, they are paralleles
because 180° = 119 + 61 = 180°
4.-
180° - 82 - 31 = 67°
180° - 67 - 98 = 15°
q = 15°
5.- 100 - x + 30 + 4x + 7x = 180
10x = 180 - 100 - 30
10x = 50°
x = 5
7x = y
y = 7(5)
y = 35°
6.-
55 + 4x + 2x - 5 = 180
6x = 180 - 50
6x = 130
x = 21.7°
7.-
slope = (1 - 2) / (3 - 0)
m = -1 / 3
( y + 1 ) = -1/3(x - 0)
8.-
9.-
slope = 3/7
P (-14 , -3)
( y + 3) = 3/7(x + 14)
10.-
Point (3,2)
A (2, 10)
B (4, 7)
slope = (7 - 10) / (4 - 2)
m = -3/2
New slope = 2/3
(y - 2) = 2/3(x - 3)
