Graph a direct variation function that goes through the point (-2, -6). what is the slope
Effectus [21]

Answer:

The slope is 3.

Step-by-step explanation:

A direct variation function will always go through the origin point (0, 0).

Therefore, we have the two points (0, 0) and (-2, -6).

We can use the slope formula to find the slope:

\displaystyle m=\frac{y_2-y_1}{x_2-x_1}

Substitute and evaluate:

\displaystyle m=\frac{0-(-6)}{0-(-2)}=\frac{6}{2}=3

Therefore, the slope of the function is 3.

To graph, simply plot (0, 0) and (-2, -6) and draw a line connecting them. This is shown below.

39. Find the length of each arc shown in red. Leave your answer in simplified radical form.
andre [41]

Answer:

The length of the arc shown in red is \frac{22}{9}\pi\ in

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference is equal to

C=2\pi r

we have

r=4\ in

substitute

C=2\pi (4)

C=8\pi\ in

step 2

Find the length of the arc in red

Remember that the length of the circumference subtends a central angle of 360 degrees

so

by proportion find the length of the arc by a central angle of 110 degrees

\frac{8\pi}{360}=\frac{x}{110}\\ \\x=8\pi*110/360\\ \\x=\frac{880}{360}\pi\ in

Simplify

\frac{880}{360}\pi=\frac{22}{9}\pi\ in

Solve step by step.<br> 7x+4(4x-14)=59
ziro4ka [17]

Answer:

x = 5

Step-by-step explanation:

7x+16x-56=59

23x -56 = 5 9

2 3 x - 5 6 + 5 6 = 5 9 + 5 6

23x=115

\frac{23x}{23} = \frac{115}{23}

x = 5
