Answer:
Step-by-step explanation:
The slope is the ratio of rise to run.
Rise is the difference of y-coordinates, run is the difference of x-coordinates.
Now, the slope is said undefined if the difference of x-coordinates is zero.
It means you have to divide by zero but it is impossible.
We have a point (- 4, - 8) and the slope is undefined.
It means our line has repeat x = -4 coordinates, it is a vertical line.
<u>Its equation will be:</u>
Answer:
1 1/2
Step-by-step explanation:
Write and solve an equation of ratios based upon the fact that the small and large triangles shown are similar:
5 6
---- = ---------
14 6 + x
Then 30 + 5x = 84, and 5x = 54, and so x = 54/5, or 10.8, or 10 4/5.
Answer:
19
Step-by-step explanation:
5 + 4^2 - 6/3
= 5 + 16 - 2
= 21 - 2
= 19
