Answer:

x = -1 and y = 6

Step-by-step explanation:

-8x + y = 14

y = 8x + 14

8x + 5y = 22

8x + 5 (8x + 14) = 22

8x + 40x +70 = 22

48x + 70 = 22

48x ÷ -48 = -48

x = -1

y = 8x + 14

y = 8 (-1) + 14

y = -8 + 14

y = 6

Answer:

Y = 6 X=-1

Step-by-step explanation:

Add the numbers 8x+-8x=0. 5y+y=6y. 22+14=36
So that means 6y=36. So Y would equal 6
Substitute the values it one of the original equations. 8x + 5(6) =22. 8x+30=22
Minus 22 from both sides.
That would give you 8x=-8
So x would equal - 1

What is sin -1(1/2) if the terminal side of 0 is located in quadrant 1.

kotykmax [81]

Answer:

Step-by-step explanation:

$\sin^{-1}(\theta)$ is going to output a number in between $\frac{-\pi}{2}$ and $\frac{\pi}{2}$ .

Luckily you are looking for $\theta$ in the 1st quadrant which is contained in the given interval above, so the answer just comes down to what the calculator returns from entering $\sin^{-1}(\frac{1}{2})$ in your calculator.

You may also use the unit circle. sine value refers to the y-coordinate on there.

So you are looking for when the y-coordinate is 1/2 in the fist quadrant which is at 30 degrees.
