Answer:
Step-by-step explanation:
If slope of two lines are equal, then they are parallel lines.
If product of the slope of two lines is (-1), then they are perpendicular lines.
C) y = x + 2
Slope m1 = 1
y = -x + 3
Slope m2 = -1
m1 * m2 = 1 * (-1) = -1
These are perpendicular lines.
D) y = 3x + 2
Slope = m1 = 3
y = 3x - 2
Slope = m2 = 3
Slopes are equal. So, they are parallel lines.
E)y= 3
This line is parallel to x -axis.
x = 4
This line is parallel to y-axis.
So, both lines are perpendicular to each other.
F) y = x + 8
slope m1 = 1
y = -x + 3
Slope = m2 = -1
M1 * m2 = 1 * (-1) = -1
So, These are perpendicular lines
Answer:
44, parallel, equals half
Step-by-step explanation:
i am not sure is this is correct but, I think that x+5 that x is 27 and the other one is 12 and the 27+5 is 32 and 32+12 is 44 so i am guessing that the BD side is 44, i guess and about the other , the first black space is parallel and the second is equals half
The volume of a cone is 1/3 pi*r^2 * h. Rearranging for height gives h = 3v / pi*r^2 = (3*294.38) / (3.14*7.5^2) = 5.00 (answer B)
ANSWER
EXPLANATION
We want to calculate the value of the angle marked z° in the diagram.
Since the given diagram is a right angle triangle, one of the angles is 90°.
The sum of the angles in a triangle is 180°.
This implies that,
We group like terms to obtain,
We simplify to obtain,
So 15 minus the flat fee is 11.25 divided by .85 is 13.23 km rounded 13km
