A line passes through (-2, -3) and (4, -6) what is the slope of the line ?

Answers

Answer 1
Answer:

The slope is the change in Y over the change in X.

Slope = (-6 - -3) / ( 4 - -2)

Slope = (-6+3) / ( 4 +2)

Slope = -3/6

Slope = -1/2

Answer 2
Answer: The slope,  or gradient, of the line is 6/-3 which is -2. The gradient is -2.

A spinner is numbered from 1 through 10 with each number equally likely to occur. what is the probability of obtaining a number less than 2 or greater than 7 in a single spin?

Answers

There are 10 numbers from 1 - 10
first we get the numbers less than 2 are (1)
secondly get the numbers greater than 7 are (8,9,10)
total = 4 numbers

The favorable probability is 4 / 10=2 / 5
hope it helps

Answer:

(2)/(5)


Step-by-step explanation:


There are 10 total outcomes [numbers from 1 to 10]

What are the numbers that are LESS THAN 2 or GREATER THAN 7?

They are 1, 8, 9, and 10.


That's a total of 4 numbers. Also, total numbers is 10. Hence the probability of obtaining numbers that are less than 2 or greater than 7 is:

(4)/(10)

Simplifying gives us a probability of  (4)/(10)=(2)/(5)

What is a complex number?

A complex number is a number of the form a + bi, where a and b are real numbers, and i = √-1

i² = (√-1)² = -1

Given the complex number:

–12i × 3i

multiplying and simplifying gives:

= -36 * i² = -36 * -1 = 36

The multiplication and simplification of the polynomial –12i × 3i gives 36

Answer A

Can 12,35,37 be a right triangle

Answers

Answer:

Yes

Step-by-step explanation:

If it could be a right triangle, then 12^2 + 35^2 would have to equal 37^2

12^2 = 144

35^2 = 1225

37^2 = 1369

1225 + 144 = 1369, which is 1369.

That means that it CAN form a right triangle

Answer:

yes

Step-by-step explanation:

Ed is doing a survey of popular colors for cars for a school report. He decides to take a sample by sitting near a busy intersection and noting the colors of the cars as they go by him. Ed counts 23 black cars, 9 red cars, 17 blue cars, 25 white cars, and 21 silver cars during 20 minutes of watching. How many more white and blue cars are there than silver and red cars?

Answers

The answer is 12.

If we represent the cars in this way:
Black cars  A = 23
Red cars    B = 9
Blue cars   C = 17
White cars D = 25
Silver cars E = 21

Then sum of white and blue cars is D + C = 25 + 17 = 42
And the sum of silver and red cars is E + B = 21 + 9 = 30

Using the subtraction:
(D+C) - (E+B) = 42 - 30 = 12

Therefore, there are 12 more white and blue cars than silver and red cars.

Answer:

12

It is 8/10 mile from liz's house to the market. Liz walked 6/10 mile, stopped for a break, and walked the rest of the way to the market. Which equation represents liz's walk?

Answers

Answer:

The equation that represents Liz's walk is:

5x + 3 = 4

Step-by-step explanation:

Liz walked 6/10 mile, stopped for a break, and walked the rest of the way to the market.

Let Liz's walk after that break be x mile.

Before the break, she had walked 6/10 miles. Adding these distances, she had walked a total of (x + 6/10) miles.

Because it is 8/10 miles from Liz's house to the market, all the walks she had to do to get to the market is 8/10 miles.

That is,

(x + 6/10) is the same as 8/10.

x + 6/10 = 8/10

Multiplying by 10, we have

10x + 6 = 8

Dividing by 2 gives

5x + 3 = 4

And this is the equation we wish to write.
