Please help me with these questions about x and y coordinates.
tatyana61 [14]

Answer:

-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

_____

<em>Comment on additional solution methods</em>

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 ...

  • 3x -y = 22
  • x - y = 14 . . . . . add 14-y to the equation given

Then the solution for y is ...

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

Which line is perpendicular to a line that has a slope of -5/6?
Anni [7]

Answer:

Line LM

Step-by-step explanation:

First, we need to know what the slope is of a line that would be perpendicular to a line with a slope of -5/6. To find this, we take the reciprocal and multiply it by -1. Therefore, the line we are looking for needs to have a slope of 6/5.

Based on the fact that the slope is positive, we can eliminate lines PQ and JK as they have a negative slope. This leaves us with lines LM and NO.

To find out whether or not it is between LM and NO, you could eyeball it by looking at the graph and simply counting which might be faster if you understand how to do that (rise/run), or you can use the pair of coordinates given to you on each line to calculate for slope.

Line LM - \frac{-3-3}{-5-0}=\frac{-6}{-5}=\frac{6}{5}

Line NO - \frac{-5-0}{-6-0}=\frac{-5}{-6}=\frac{5}{6}

Based on this, we know that line LM is perpendicular to a line that has a slope of -5/6.

<em>If you need help on calculating slope from two points, I'd suggest watching this video: </em><u>https://www.brightstorm.com/math/algebra/linear-equations-and-their-graphs/finding-the-slope-of-a-line-from-2-points-problem-1/#:~:text=Use%20the%20slope%20formula%20to,second%20points%20are%20x2%2C%20y2.</u>
