Answer:

5.2.

Step-by-step explanation:

The question states that this point is on segment LM, with the distance between this point and L\! being (3/5) the distance between L to M.

It could be shown (using a pair of similar right triangles) that the (3/5) ratio applies not only to the (sloped) distance between this point and L, but to the vertical distance as well.

The vertical distance between this point and L\! would also be (3/5) the vertical distance between \! L and M.

The vertical distance between \! L and M is the difference between their y coordinates, 8 - 1 = 7.

The vertical distance between this point and L would be (3/5) of the vertical distance between L\! and M\!, 7 \times (3/5) = 21/5.

Since M\! is above L\!, any point on the segment between these two points would also be above L. Add the vertical distance between \! L and the requested point to the y coordinate of L\!\! to find the y\! coordinate of the requested point: (21/5) + 1 = 26/5 = 5.2.

What is the slope of the line?<br><br> A. 2<br> B. -2<br> C. 1/2<br> D. -1/2
iogann1982 [59]

slope m = - 2 → B

calculate m using the ' gradient formula '

m = (y₂ - y₁)/(x₂ - x₁)

choosing 2 'clear ' coordinates from the graph of the line

(x₁, y₁) = (0, 7) and (x₂, y₂) = (7, - 5\frac{(- 5 - 7)}{(6 - 0)}) = \frac{- 12}{6} = - 2

Find the probability of each event. There are 4 red marbles, 2 black marbles, and 2 green marbles in a box. P(red) = P ( red or
nevsk [136]

Answer: P(red): 1/2

P(red or black):3/4

Step-by-step explanation: Count the total number of marbles. There are 8. Since there are 4 red marbles out of the 8, put this into a fraction. It will be 4/8, but simplify to 1/2. The P(red) is 1/2.

Since there are 4 red marbles and 2 black marbles, add them. There are 6 out of the 8 marbles. The fraction is 6/8 simplify to 3/4. The P(red or black) is 3/4.
