Step-by-step explanation:
Assume that two lines x and y are perpendicular to the line z.
+) x intersects z at point A => Angle A1 = 90°
+) y intersects z at point B => Angle B1 = 90°
As it can be seen from the figure that Angle A1 and Angle B1 are corresponding angles and they are congruent.
According to the corresponding angle theorem, when two parallel lines are cut by a transversal, the pair of corresponding angles are congruent and vice versa, when two lines are cut by the same line and the pair of corresponding angles are congruent, they are parallel.
=> x and y are parallel.
Yes, you are correct to use proportions because they are similar triangles.
Answer:
6x = 12 : Divide both sides of the equation 6
6 ( x - 12 ) = -3x - 5: Distrubite the 6 to clear the paranthesis
6x + 5 = 9x - 1 : Subtract 6 from both sides of the equation
Answer:
2.19*17.00
=37.23
=$37
Step-by-step explanation:
x = -1
y = 1
To find this, input the equation into a graphing calculator, whether online or an actual one, and you have two options:
1 - Search for the points in which the line crosses the x and or y axis.
2 - Hit 2nd Graph to access the table and find when x and y equal zero.
Hope this helps!
