(?,6) is on the line 2x – 7y = 0. What is the other half of the coordinate
yarga [219]
If we plug the given value of y = 6 into the equation, we get:
2x-7\times6=0
which can be rearranged to
2x = 42
giving x = 21.
Therefore the other half of the coordinate is 21.

I need help with #22
maria [59]

Answer:

4 = y \\ 4 = x

Step-by-step explanation:

The isosceles triangle containing the side of <em>y</em><em> </em><em>+</em><em> </em><em>12</em><em> </em>is congruent to <em>3x² - </em><em>32</em><em> </em>[<em>base angles</em> are congruent], and if you look closer, they are also equivalent to all three sides of the equilateral triangle <em>adjacent</em> to the isosceles triangle. So, we will be working with alot gadgets here, if you know what I mean. Anyway, this is how we start out:

5y - 4 = y + 12

-5y - 5y

___________________

-4 = -4y + 12

-12 - 12

____________

-16 = -4y

___ ___

-4 -4

4 = y [Plug this back into both equations to get the value of 16.]

Next, you will set <em>3x² - 32 </em>equal to 16:

16 = 3{x}^{2} - 32

+32 + 32

_________________

48 = 3x²

__ ___

3 3

16 = x²

4 = x [In this case, we want the NON-NEGATIVE root because inputting a -4 for <em>x</em><em> </em>will not give us identical answers.]

I am joyous to assist you anytime.
