Mariana [72]

Answer:

\sec \theta = -\frac{\sqrt{61}}{5}

Step-by-step explanation:

The secant can be found by the following trigonometric relation:

\sec \theta = \frac{1}{\cos \theta}

\sec \theta = \frac{1}{\frac{x}{r} }

\sec \theta = \frac{r}{x}

\sec \theta = \frac{\sqrt{x^{2}+y^{2}}}{x}

\sec \theta = \frac{\sqrt{(-5)^{2}+(-6)^{2}}}{(-5)}

\sec \theta = -\frac{\sqrt{61}}{5}

Please help one problem I’ll give brainliest..
strojnjashka [21]

Answer:

Your answer is infinitely many solutions

Step-by-step explanation:

To use elimination you have to get one of the variables to be the opposite of each other, so here you would do:

-2(2x+y = 7)

   4x+2y= 14

You multiply the top by -2 to get the opposite of 2y, which is -2y. This in turn multiplies everything by -2 on the top solution giving us the top equation below.

  -4x-2y = -14

+ 4x+2y = 14

--------------------

      0 = 0

If you add those 2 solutions then you get 0 = 0, which is infinitely many solutions
