Answer:

x=3.4 y=-5.8 (the steps are in order and I explained to the best of my ability)

Step-by-step explanation:

x+3y=-14 substitute the x for -14-3y in the second problem

x=-14-3y 2(-14-3y)-4y=30

-28-6y-4y=30

-10y=58

y=-5.8

substitute the y in the first equation for -5.8

x+3(-5.8)=-14

x-17.4=-14

x=3.4

Find sec Θ if the terminal side of Θ in standard position contains the point (4, -3)

CaHeK987 [17]

If we plot that point we find ourselves in QIV. The distance along the x axis is 4, and the distance down from that point is -3. If we create a right triangle with that segment, that segment serves as the hypotenuse of the triangle. We need its measure. Using Pythagorean's theorem, $4^2+-3^2=c^2$ and $16+9=c^2$ . We see that c = 5. We need now to find the secant of that right triangle. Secant if the co-identity of cosine which is side adjacent over hypotenuse. That means that secant is the hypotenuse over the side adjacent. So our secant theta = 5/4
