Let W be a point between points U and V on . If UV = 13, UW = 2y – 9, and WV = y – 5, solve for y.

Answers

Answer 1

Answer:

Answer:

The value of y is 9.

Step-by-step explanation:

Given : W be a point between points U and V also, UV = 13, UW = 2y – 9, and WV = y – 5

We have to solve for y.

Since, W is a point between points U and V .

Then distance of point W from U and distance of point from V is equal to the distance of UV.

Then, UW + WV = UV

Substitute , the values, we get,

Then 2y – 9 + y – 5 = 13

Solving for y , we get,

⇒ 3y - 14 = 13

⇒ 3y = 13 + 14

⇒ 3y = 27

⇒ y = 9

Thus, the value of y is 9.

Answer 2

Answer: you would do 9/2
9/2=4.5
2*4.5=9

IGNORE WORK ON PAPER PLS HELP3. A game at an arcade consists of a balloon that is inflated little-by-little during each round of play. The player wins. when the balloon pops. The amount of air (in cubic inches) that is needed to make the balloon pop can be modeled by a uniform distribution on the interval from 25 to 35 cubic inches of air. (a) Draw a density curve to model the amount of air that is needed to make the balloon pop. Be sure to include scales on both axes. (b) About what percent of the time will the balloon pop upon receiving at most 28 cubic inches of air? (c) Find the first quartile (Q1) of this distribution. 4. The manager of the arcade wants to know how quickly players switch from one game to another. After conducting a study, he concludes that the amount of time that people spend playing a game before switching to a different game can be modeled by a normal distribution with mean 2.1 minutes and standard deviation 0.4 minutes. Sketch the normal density curve. Label the mean and the points that are 1, 2, and 3 standard deviations from the mean.

C.{(9, -1), (-1, 9), (9, 2), (2, -1)}
D.{(5, -7), (4, 6), (-3, 8), (5,9)}

Answers

A function means that each x can only have one y-value

B, C, and D are NOT functions because they have x-values that have multiple y-values.

For example

B. has two values for -4:

(-4, 8) and (-4, -8)

C. has two values for 9:

(9, -1) and (9, 2)

D. has two values for 5:

(5, -7) and (5, 9)

This makes A. the only function

Two angles in a triangle add up to 135 degrees what is the size of the third angle?

Answers

This question is checking to see if you remember what the three angles
of any triangle always add up to. Apparently you don't, or you would not
need to go out looking for somebody who does.

The three angles inside every triangle always add up to 180° .

If two of them add up to 135° , then that leaves

(180° - 135°) = 45° .

for the one remaining angle.
