Find the ordered pairs for the x- and y-intercepts of the equation 3x - 2y =18

1 answer:

5 0

X-int:let y=0
3x-2(0)=18
3x=18
divide both sides by 3
therefore x=6
y-int:let x=0
3(0)-2y=18
-2y=18
we divide both side by -2
therefore y=-9

Answer:

(d) -√((2+√2)/(2-√2))

Step-by-step explanation:

5π/8 is a 2nd-quadrant angle whose reference angle is greater than π/4. This means the tangent is negative with a magnitude greater than 1. The only reasonable choice is ...

$\displaystyle -\sqrt{\frac{2+\sqrt{2}}{2-\sqrt{2}}}$

<em>Additional comment</em>

This simplifies to -(1+√2). Your calculator can verify the choice for you.
