The table is an example of direct variation. What is the missing value of y?

krok68 [10]

Based on this table, I infer that this is your answer for the missing y:

y = -24

By simplifying this, I find that this is the equation for the table:
1x = -.75y

6 = 14 - x <br> One step equations review

Ymorist [56]

Answer:

x = 8

Step-by-step explanation:

6 = 14 - x

chance the equation around so it is solvable

14 - x = 6

14 - 6 = x

now solve

14 - 6 = 8

that means x equals 8 so

6 = 14 - 8

=> k = .15
So, W = .15r^3
When r=3 inch, W = .15*27 = 4.05 pounds

A kite is flying 79 ft off the ground, and its string is pulled taut. The angle of elevation of the kite is 50°. Find the length

Art [367]

Answer:

If the kite has an 11 ft line attached to it and it casts an 8 feet shadow, we will have a rectangle triangle (see picture below).

To find the height x of the kite, we can apply the Pythagorean theorem.

x² = 11² - 8²

x² = 121 - 64

x² = 57

x =√57

Graph the line with slope 1/2<br> that passes through the point (-1,2).

enyata [817]

9514 1404 393

Answer:

see the attachment for a graph

Step-by-step explanation:

With the given point and slope, the equation of the line can be written in point-slope form:

y -k = m(x -h) . . . . . line with slope m through point (h, k)

y -2 = 1/2(x +1) . . . . line with slope 1/2 through point (-1, 2)

Slope is the ratio of rise to run, so a slope of 1/2 means the line will rise 1 unit for each 2 units of run (to the right). If you're plotting this by hand, you can identify a second point that is 2 right and 1 up from the given point:

(-1 +2, 2 +1) = (1, 3).

You can draw your line through those two points.
