PLEASE ANSWER QUICKLY...
ycow [4]

Answer:

(6, -2)

Step-by-step explanation:

Since <em>x = 4 and y = 3</em>, we can plug that into the second ordered pair: <em>(4 + 2, 3 - 5)</em>

Since 4 + 2 = 6 and 3 - 5 = -2, our new ordered pair is (6, -2)

Which sentence is true?
Sloan [31]

Answer:

Natural numbers are all numbers 1, 2, 3, 4… They are the numbers you usually count and they will continue on into infinity.

Whole numbers are all natural numbers including 0 e.g. 0, 1, 2, 3, 4…

Integers include all whole numbers and their negative counterpart e.g. …-4, -3, -2, -1, 0,1, 2, 3, 4,…

All integers belong to the rational numbers. A rational number is a number

ab,b≠0

Where a and b are both integers.

Example

The number 4 is an integer as well as a rational number. As it can be written without a decimal component it belongs to the integers. It is a rational number because it can be written as:

41

or

82

or even

−8−2

Whereas

15=0.2

is a rational number but not an integer.

A rational number written in a decimal form can either be terminating as in:

15=0.2

Or repeating as in

56=0.83333...

All rational numbers belong to the real numbers.

If you look at a numeral line

picture05

You notice that all integers, as well as all rational numbers, are at a specific distance from 0. This distance between a number x and 0 is called a number's absolute value. It is shown with the symbol

|x|

If two numbers are at the same distance from 0 as in the case of 10 and -10 they are called opposites. Opposites have the same absolute value since they are both at the same distance from 0.

|10|=10=|−10|

Which equation is the inverse of y = 7x2 – 10?
MrRissso [65]

we have

y=7x^{2}-10

To find the inverse

Step 1

Exchanges the variables, x for y and y for x

x=7y^{2}-10

Step 2

Isolate the variable y

x=7y^{2}-10

7y^{2}=x+10

y^{2}= \frac{x+10}{7}

Square Root both sides

y=(+/-)\sqrt{\frac{x+10}{7}}

Step 3

Let

f(x)^{-1}=y

so

f(x)^{-1}=(+/-)\sqrt{\frac{x+10}{7}}

therefore

<u>the answer is</u>

The inverse is  

f(x)^{-1}=(+/-)\sqrt{\frac{x+10}{7}}

Out of 100 students,15 passed in english, 12 passed in mathematics, 8 in science, 6 in english and mathematics, 7 in mathematics
Lyrx [107]
Because there are 4 students who passed in all subjects, we can say that only 2 students passed in English and Mathematics only, only 3 students passed in Mathematics and Science only, and no one passed in English and Science only.

Given that we have deduced the number of students who passed in two subjects, we can now solve for the number of students who passed only one subject. 
                English = 15 - (4 + 2 + 0) = 9
                Mathematics = 12 - (4 + 3 + 2) = 3
                Science = 8 - (4 + 3 + 0) = 1

1. In English but not in Science,
                    9 + 2 = 11
2. In Mathematics and Science but not in English
                    3 + 3 + 1 = 7
3. In Mathematics only 
                             = 3
3. More than one subject only
                   3 + 4 + 2 + 9 = 18

It will really be helpful if you draw yourself a Venn Diagram for this item.
