Me with these questions about x and y coordinates.

-10

Step-by-step explanation:

You are asked to tell the y-value of the solution. You can find the whole solution and then report the y-value, or you can just find the y part of the solution. We choose the latter.

This is basically done by eliminating the x-variable. It can be done using the "elimination" method of solving these equations. And it can also be done using the "substitution" method of solving these equations. We choose the latter.

Add 14 to the second equation to solve for x:

... x = y + 14

Substitute this into the first equation.

... 3(y +14) -y = 22

... 2y +42 = 22 . . . . . . simplify

... y +21 = 11 . . . . . . . . divide by 2

... y = -10 . . . . . . . . . .  subtract 21

Comment on additional solution methods

A graphing calculator can show you the solution, as in the attachment. Of the solution (x, y) = (4, -10), we are only interested in y = -10.

Cramer's rule can find just one variable value, too. For that, it is convenient to write the system as ...

Then the solution for y is ...

... y = (22·1 -14·3)/(-1·1 -(-1)·3) = -20/2 = -10

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

the answer is stop cheating on things stoopid
