Write an equation for the line parallel to the given line that contains C.
lyudmila [28]

ANSWER

y= - 4x + 18

EXPLANATION

The given line has equation;

y =  - 4x + 5

The slope of this line is

-4

The given line is parallel to this line so it has the same slope:

m =  - 4

The equation of this line is in the form:

y-y_1=m(x-x_1)

We substitute the slope and the point:

(3,6)

y-6= - 4(x-3)

y= - 4x + 12+ 6

y= - 4x + 18

Which inequality would result in the shaded solution on the unit circle to the right?
omeli [17]
<h3>Answer: Choice B</h3>

Explanation:

Cosine is positive in quadrants I and IV, but quadrant IV isn't shaded in so we can rule out choice A.

Sine is positive in quadrants I and II. So far it looks like choice B could work. In fact, it's the answer because sin(pi/6) = 1/2 and sin(5pi/6) = 1/2. So if 0 ≤ sin(x) < 1/2, then we'd shade the region between theta = 0 and theta = pi/6; as well as the region from theta = 5pi/6 to theta = pi.

Choice C is ruled out because tangent is positive in quadrants I and III, but quadrant III isn't shaded.

Choice D is ruled out for similar reasoning as choice A. Recall that \sec(x) = \frac{1}{\cos(x)}
