Answer:

y=2, x=-1

Step-by-step explanation:

We can add the two equations together to eliminate x:

6x+5y+(-6x)+7y=4+20

12y=24

y=2

We plug y into the first equation and get

6x+5(2)=4

6x+10=4

6x=-6

x=-1

Given m||n, find the value of x.<br> kt<br> (7-10)<br> (6x-5)°
Dennis_Churaev [7]

Answer:

15

Step-by-step explanation:

So, leets look at the graph.

We can see that the lines being solved for tecnically make up 180 degrees.

This is because the value of the angles on line m are equal to the value of the angles on line n.

So, we know that the total line, 180 degrees, is 7x-10, and 6x-5.

Lets combine these two equations, and subtract them from 180 degrees to solve for x:

7x-1+6x-5

=

13x-15

Now to solve for x:

13x-15=180

Add 15 to both sides to get 13x alone:

13x=195

Then divide both sides by 13 to get x alone:

x=15

So our value of x is 15!

Hope this helps! :)

This is my next Trigonometry question I am needed help on- I just want to be sure I've got it right, or if not, then the steps I
makkiz [27]
\bf \textit{simmetry identities}\\\\&#10;sin(-\theta)=-sin(\theta)\\\\&#10;-------------------------------\\\\&#10;sin(-\theta)=\cfrac{1}{5}\implies -sin(\theta)=\cfrac{1}{5}\implies sin(\theta)=\cfrac{-1}{5}\cfrac{\leftarrow opposite=b}{\leftarrow hypotenuse=c}&#10;\\\\\\&#10;c^2=a^2+b^2\implies \pm\sqrt{c^2-b^2}=a\implies \pm\sqrt{5^2-(-1)^2}=a&#10;\\\\\\&#10;\pm\sqrt{24}=a\implies \pm2\sqrt{6}=a

so. hmm which is it? the +/- ?   well, neverminding for a second, the value of tangent, just looking at the sign, the tangent is positive,

tangent = opposite/adjacent.... so that only happens, when both are the same sign, + or - both

now, we know the sine is -1/5.. if the sine is negative, the cosine also has t to be negative, so we'd use the -2√(6) = a

thus     \bf cos(\theta)=\cfrac{adjacent}{hypotenuse}\implies cos(\theta)=\cfrac{-2\sqrt{6}}{5}
