Answer:

y = (-1/2)x

Step-by-step explanation:

As we go from (-4, 2) to (6, -3), x (the "run") increases by 10 and y (the "rise") decreases by 5. Thus, the slope of the line connecting these two points is m = rise / run = m = -5/10, or m = -1/2.

We adapt the slope-intercept form as follows: y = mx + b becomes

2 = (-1/2)(-4) + b, or

2 = 2 + b. Therefore, b must be 0. The desired eequation is y = (-1/2)x.

Answer:A

Step-by-step explanation:

we need to first find the answer to the equation.

2x+6=22

6-6=0

22-6=16

2x=16

divide both sides by 2

x=8

A. x-6=6

if u plug in 12, you get 12-6=6 which is true
all the other ones would be false if you plugged in 12

Given cos t = 1/2 tan 0 find sin (t) and sec (t)

777dan777 [17]

Answer:

Sin(t) = $\frac{\sqrt{3} }{2} }$ and $sec(t) =2$

Step-by-step explanation:

The secant function is the reciprocal function of the cosine function. Therefore, given that $sec(t) = \frac{1}{cos(t)}$ then, if $cos(t) = \frac{1}{2}$ then $sec(t) =2$ .

On the other hand, if cos (t) = 1/2 ⇒ t = ± $\frac{\pi}{3}$

Then, the sin( $\frac{\pi}{3}$ ) = $\frac{\sqrt{3} }{2} }$
