Tell whether the lines with the given slopes are parallel, perpendicular, or neither. Line 1: m = 2 2)

Answer and Step-by-step explanation: Two lines can be parallel, perpendicular or none of them. The difference is in the slope of a line.

<u>Slope</u> is the change in y over the change in x, or, in other words, it is the steepness of the line.

Two lines are parallel if they don't intersect. So, they have the same slope and different y-intercept. For example:

f(x) = m₁x + b₁

g(x) = m₂x + b₂

Functions f(x) and g(x) are parallel if

m₁ = m₂ and b₁ ≠ b₂

Two lines are perpendicular when they intersect at a 90° angle. For that to happen, the multiplication of the slope of each function must result in -1. For example:

h(x) = m₃x + b₃

j(x) = m₄x + b₄

The functions will be perpendicular if:

m_{3}m_{4}=-1

If the slopes are not the same or reciprocal, the lines are neither.

aliya0001 [1]
The area of a trapezoid with base lengths 7 in and 19 in is given by
  A = (1/2)(b1 + b2)h
  A = (1/2)(7 +19)·7 = 91

The appropriate choice is
  D. 91 in²


_____
It can also be figured by adding the area of the 7 in square (49 in²) to the area of the 7×12 in right triangle (42 in²).

In the triangle below,
Greeley [361]

Answer:

12.3

Step-by-step explanation:

You will use cosine to solve for y because you are given the hypontenuse and need to find the adjacent side.

cos 35 degrees = adjacent/hypontenuse

cos 35 = y/ 15

15( cos35 ) = y

y=12.287

=12.3
