Find m∠dob. a) 36.5° b) 73° c) 107° eliminate d) 136°

The solution is 73°. According to one of the circle theorems, the angle formed by the intersecting chords is equal to the average of the arcs intercepted by the angle and its vertical angle.

 = 107°

So m∠DOC = 107°

Since m∠DOB is supplementary to m∠>DOC we know that its measure is 73°.

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
