Determine if the lines that pass through the given points are parallel, perpendicular or neither. Line A: (-3, 5) and (0, 7) Line B: (6, 2) and (9, 4)

Answers

Answer 1

Answer: If two lines are parallel, their slopes will be equal. If they are perpendicular, the slope of the first line multiplied by the slope of the second line will equal 1. If they are neither, they won't have any special relationship.

Line A:
Slope = (7 - 5)/(0 - -3), which is equal to 1/3

Line B:
Slope = (4 - 2)/(9 - 6), which is also equal to 1/3.

The two slopes are the same, therefore they are parallel.

Answer 2

Answer: It is parallel due to the fact that it is the exact same number with one being positive and one being negative.

Answer :

5.3 gallons

Given :

a set of data of the change of amount of water.

To find :

It's range

Solution :

To find the range, firstly we will arrange the data in ascending order and then deduct the lowest value from the highest one.

-2.5, -1.9 ,-1.1 ,-0.4 , 0.2 , 0.9 , 1.5 , 1.8 , 2.5 , 2.8
Lowest data : 2.8
Highest data : -2.5
Range : [ 2.8 - (2.5) ] gallons
Range : 5.3 gallons

Thus, the range in the change of the amount of water is 5.3 gallons.

Determine the quotient of 1/3/4 divided by 2/5

Answers

Answer:

First turn any mixed numbers into improper fractions. 1 3/4 would be 7/4. Becuase you multiply the whole number by the denominator and then add the numerator.

So now you have 7/4 divided by 2/5. Whenever you divide, you flip the 2nd fraction upside down... known as the reciprocal. And after that you multiply the first number by the upside down 2nd number.

So now you have 7/4 X 5/2. When multiplying, just multiply the numerators across and the denominators across. As your answer, you get 35/8 or 4 3/8.

Step-by-step explanation:

Answer:

35/8 or 4 3/8

Step-by-step explanation:

whatever works for you. but when you use a caucalater you get 35/8.

actually all the whole numbers are kind of rational numbers like : 1/1 , 2/1 , 3/1 , ...
so there are some rational numbers that are whole numbers too :))
i hope this be helpful
have a nice day

No. ALL whole numbers are rational. And what's with all the plus signs ? ? They really make your questions hard to read.
