Answer: this is really simple so we know that the coordinate points have an X and a Y value we see that (4,-2)

Step-by-step explanation:

We just plug it in for example

-2 for Y because it’s the Y value and 4 for x because it’s the X value

-2=1/2(4)-4

*we know that half of 4 is 2*

now the equation is -2=2-4

finally we just subtract 2-4 which is -2

-2=-2 so the equation is right

Answer:

\huge\boxed{\texttt{Yes. Explanation for why.}}

Step-by-step explanation:

If we have the equation y = \frac{1}{2}x - 4 and we want to test if the point (4,–2) satisfies the equation, we can plug the x and y values into the equation and see if they make the equation true.

4 is the x value, -2 is the y.

-2 = (\frac{1}{2}\cdot4)-4

-2 = 2 - 4

-2 = -2

So this does satisfy the equation.

Hope this helped!

Which of the following functions have a vertical asymptote for values of θ such that cos θ = 1? Select two answers.
valentina_108 [34]
Well costheta=1, at 0, 2pi,... 
knowing this we can exclude the first two as the are not undefined anywhere. 
tan is sin/cos, at 0 sin is also 0 so it becomes 0/1 which is 0, not undefined.
sec is1/cos, cos is 1, this is just 1
csc is 1/sin, sin is 0, 1/0 is undefined, meaning there will be an asymptote 
cot is cos/sin, this is again 1/0, so it is also an asymptote
The last two answers are the ones you want

Answer:

<em>angle ABD =</em><u><em>55 degree</em></u>

<em>angle BCD= </em><u><em>125 degree</em></u>

Step-by-step explanation:

angle ABD and angle DBC are supplementary angles.

Hence, angle ABD +angle DBC = 180 --equation 1

angle ABD = (2x+15) ---equation 2

angle BCD = (4x+45) ------equation 3

ABD+DBC=180

(2x+15) + ( 4x+45 ) = 180

2x+4x+15+45=180

6x+60=180

6x=180-60

6x=120

x=120/6=20

angle ABD= 2x+15= 2(20) +15

                              =40+15= 55 degree

angle BCD= 4x+45 = 4(20) +45

                                = 80+45= 125 degree

Hence, angle ABD =55 degree

            angle BCD= 125 degree

<em>Hope this helps.</em>
