Which equation does the graph below represent?<br> y=1/3+x<br> y=1/3x<br> y=3+x<br> y=3x
barxatty [35]
Lets find 2 points, one obvious one is (0,0), another point is (12,4)

Slope = \frac{4-0}{12-0} =\frac{4}{12} = \frac{4\times 1}{4\times 3} = \frac{1}{3}

y = mx + b

m is the slope

we got m = 1/3

We can eliminate answer choices C and D.

y = 1/3x + b

we need to solve for b

Plug in the point (0,0) and solve for b

0 = 1/3(0) + b

0 = 0 + b

b = 0

The equation of the line is y = 1/3x + 0, or y = 1/3x

Your answer is B.

In the figure below, BD and AC are diameters of circle P.
elena-14-01-66 [18.8K]

Answer:

arc\ DC=30^o

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

The point P is the center of the circle (the drawing is not a scale )

step 1

Find the measure of angle ∠CPD

we know that

m\angle CPD+150^o=180^o ---> by supplementary angles (form a linear pair)

m\angle CPD=180^o-150^o=30^o

step 2

Find the measure of arc DC

we know that

<u><em>Central angle</em></u> is the angle that has its vertex in the center of the circumference and the sides are radii of it

so

arc\ DC=m\angle CPD ----> by central angle

therefore

arc\ DC=30^o

The sum of three consecutive numbers is 46. Find the
Citrus2011 [14]

Let the three consecutive number be x,x+1 and x+2.

It is given sum of three consecutive numbers is 46.

So,x+x+1+x+2=46

3x+3=46.

Subtracting 3 both sides

3x=46-3

3x=43.

x= \frac{43}{3}.

Since \frac{43}{3}. is not an integer there is no true answer to this problem.
