Y = -5/4x + 1.....the slope here is -5/4. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign, resulting in 4/5 (u see how I flipped -5/4 and turned it into 4/5...I then changed the sign and made it 4/5)

y = mx + b
slope(m) = 4/5 ....we are using the negative reciprocal here
(2,6)...x = 2 and y = 6
now we sub and find b, the y int
6 = 4/5(2) + b
6 = 8/5 + b
6 - 8/5 = b
30/5 - 8/5 = b
22/5 = b

so ur perpendicular equation is : y = 4/5x + 22/5

What is the probability of getting blue and green on a spinner that is 3/10 and 1/5 blue
DaniilM [7]
So 3/10 green and 1/5 blue.  First, let's convert them into equal fractions.  Now we have 3/10 and 2/10.  When combined, it is 5/10.  That means there is a 50% chance you will land on blue or green.

RSM wants to send four of its 18 Math Challenge teachers to a conference. How many combinations of four teachers include exactly
tatiyna

Answer:

1120 combinations of four teachers include exactly one of either Mrs. Vera or Mr. Jan.

Step-by-step explanation:

The order in which the teachers are chosen is not important, which means that the combinations formula is used to solve this question.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

In this question:

1 from a set of 2(Either Mrs. Vera or Mr. Jan).

3 from a set of 18 - 2 = 16. So

C_{2,1}C_{16,3} = \frac{2!}{1!1!} \times \frac{16!}{3!13!} = 1120

1120 combinations of four teachers include exactly one of either Mrs. Vera or Mr. Jan.
