Given two points m and n on the coordinate plane, find the slope of line mn, and state the slope of the line perpendicular to li

ololo11 [35]

The slope of the line MN where M (9,6) and N (1,4) can be obtained by obtaining the rate of the rise over the run. This is shown below:

(y2 - y1)/(x2 - x1) = (4 - 6)/(1 - 9) = (-2)/(-8)
m1 = 1/4

The slope of the line perpendicular to line MN can be obtained by taking the negative reciprocal of the slope of line MN.

m1 = 1/4
m2 = -1/m1 = -1/(1/4) = -4

Therefore, the slope of the line perpendicular to line MN is -4.

Simplify the expression 2p + 3/4p + 6 - p - 3 1/2

lozanna [386]

Answer:

The simplified expression is "7p/4 + 2 1/2" or "1.75p + 2.5".

Step-by-step explanation:

2p + 3/4p + 6 - p - 3 1/2
=> (2p - p + 3/4p) + (6 - 3.5)
=> 1.75p + 2.5

Hence, the simplified expression is "7p/4 + 2 1/2" or "1.75p + 2.5". Any of these would work.

In the game of Pick-A-Ball without replacement, there are 10 colored balls: 3 red, 4 white, and 3 blue. The balls have been plac

Margarita [4]

Answer:A)0.27

B)0.78

Step-by-step explanation:

This is the probability of picking 2balls of same color.

P(RR)+Pr(WW)+Pr(BB)

3/10×2/9+4/10× 3/10+3/10 ×2/9=6/90+12/90+6/90=

24/90=4/15=0.27

B)if the first ball is not returned, then there are 9 balls left.

Then probability of same color will be

PrB+PrW+PrR

2/9+3/9+2/9=

7/9=0.78

Answer:

$3w+10>2w+15$

Step-by-step explanation:

If Jerry initially releases 10 videos a week and creates an additional 3 each week, he will create a total of $3w+10$ videos, where $w$ is the number of weeks. If Martin initially releases 15 videos a week and creates an additional 2 each week, he will create a total of $2w+10$ videos, since $w$ is maintained. Therefore, the inequality $\fbox{$3w+10>2w+15$}$ can be used to find who creates more videos, where $w$ is the number of weeks.
