How do you use the slope to prove lines are parallel or perpendicular

Mathematics
1 answer:
zaharov [31]2 years ago

In order to find if two lines are parallel or perpendicular or neither, following rules are used:

  1. If the slope of two lines is the same, the two lines will be parallel
  2. If the product of slopes of two lines is -1, the two lines will be perpendicular to each other.
  3. If none of the above two conditions is being satisfied, this mean lines are neither parallel nor perpendicular.

So the steps that must be followed are:

  • Find the slope of the given lines.
  • Use the values of the slope to check which of the above point is being satisfied and draw the conclusion accordingly.

Answer:

type 2 in the first box,

13/4 in the second box, and

-9/8 in the third one

Step-by-step explanation:Notice that you are asked to write the following quadratic expression in vertex form, so you need to find the "x" value of the vertex, and then the "y" value of the vertex:

x_{vertex}= -b/2a

Which in our case is: -13/4

and the value of the y for the vertex is obtained using the functional expression when x equals -13/4:

f(-13/4)= -9/8

Then your expression for this quadratic should be:

f(x)=2\,(x+\frac{13}{4} )^2+(-\frac{9}{8})

Then type 2 in the first box, 13/4 in the second box, and -9/8 in the third one

How do i find x and y?​
mario62 [17]

Answer:

y=65

x=50

Step-by-step explanation:

exterior angle of a triamgle is equal to sum of two interior angles

so

2y=130(as it is isosceles triangle)

y=65

we know y+y+x=180(sum of all angles of triangle)and (vertically opposite angle)

therefore, x=50
