For what value of x is line m parallel to line n?

Mathematics

kogti [31]2 years ago

Answer:

x=10

Step-by-step explanation:

Here, we can use an angle rule.

We see that angles (8x+50)° and 130° are under a sort of F shape, where lines m and n are the horizontal parts of the letter and where the diagonal line is the vertical part of the letter.


This means we can use the rule:

Corresponding angles are equal.

This means that:

8x + 50 = 130

We can now use this equation we have formed to solve for x:

8x + 50 = 130\\8x = 80\\x = 10

Therefore, our final answer is x=10.

Could someone explain why (-4)² is equal to 16 but -4² is equal to -16​
erica [24]

Answer:

It's all about the brackets.

Step-by-step explanation:

If we do (-4)^2, the brackets make it -4 x -4 and the two negatives make a positive of 16.

If we do -4^2, that means that the 4 is squared before putting the minus sign there so you have 4x4 = 16 then put the minus to get -16.

Hope this helps!

Given n//p m<2=50 degrees what is m<7?
Bogdan [553]

Answer: m∠7=130°

Step-by-step explanation:

  If two parallel lines are cut by another line (transversal), each one will have four angles surrounding the intersection.

By definition,  the adjacent angles of each parallel line, are supplementary, this means that they add up 180°.

Then, if m∠2=50°, then  m∠3 is:

m∠3=180-50=130°

By definition, the angles that are in the same relative position are know as corresponding angles and they are congruent.

Therefore:

m∠3=m∠7

m∠7=130°

No idea how to graph this
Anit [1.1K]

Answer:

the graph will start at y1 and go down 1 and right 2 for every point.

Step-by-step explanation: since the x is negative you know that the graph is going to be negative so from left to right it will be going from top to bottom. next you look at the 1/2 which just states that every point on that line will will be 1 down and two right from the previous point. now you look at the +1 which just says that the graph will cross the y axis a 1.
