What is x 1/4(8x+12)=21

tatiyna

Answer:

x = 9

Step-by-step explanation:

1/4(8x+12) =21

1/4 * 8x = 2x

1/4 * 12 = 3

2x + 3 = 21

21 - 3 = 18

2x = 18

18/2 = 9

x = 9

In the diagram, VW = 3, WX = 4, and VX = 8. Is line WX tangent to point V?

anastassius [24]

No. If line WX would have been a tangent, the angle VWX should have been 90 degrees. If it would have been 90 degrees, using the pythagoras theorem, side VX should have been 5. But it's not 5, neither angle VWX is 90 degrees nor is the line WX a tangent to the circle

Write the equation of the line that passes through (−2, 6) and (2, 14) in slope-intercept form. (2 points)

melisa1 [442]

Answer:

$y = 4x + 14$

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation we must first find the slope of the line

Slope of the line using points (−2, 6) and (2, 14) is

$m = \frac{14 - 6}{2 + 2} = \frac{8}{2} = 4$

Now we use the slope and any of the points to find the equation of the line.

Equation of the line using point ( - 2, 6) and slope 4 is

$y - 6 = 4(x + 2) \\ y - 6 = 4x + 8 \\ y = 4x + 8 + 6$

We have the final answer as

$y = 4x + 14$

Hope this helps you
