The graph number [2], represents a function.
What is a expression? What is a mathematical equation? What is Equation modelling ?A mathematical function is made up of terms (constants and variables) separated by mathematical operators having a dependent and independent variable. A mathematical equation is used to equate two expressions. For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of [x] for which y exists.
We have some graphs of relations as shown.
Only the graph number [2], represents a function as for a single value value of [x], a single unique value of [y] exists.
Therefore, the graph number [2], represents a function.

The sum of four consecutive odd numbers is 80 find the number
Answers
Answer:
Let the numbers are
x, (x+2), (x-2) and (x+4)
Step-by-step explanation:
x + x +2 +x - 2+x+4 = 80
4x +4 = 80
4x =80-44x = 76
4x = 76
x = 76/4
x = 19x
x=19
(x+2) =19+2=21
(x-2) = 19-2=17
(x+4)=(19+4)=23

how do i change the fraction into a decimal?
3/4 as a decimal?
Answers
Answer:
0.75
Step-by-step explanation:
1. To change 3/4 into a decimal, you have to divide 3 by 4.
2. (Check out the image below to see how to divide 3 by 4.)
Answer:
3/4 is expressed as 0.75 in the decimal form.
Step-by-step explanation:
Fractions and decimals are two ways to represent the same numbers. A decimal number can be defined as a number whose whole number part and fractional part is separated by a decimal point. A fraction is represented as a numerical value that is defined as a part of a whole.
To convert any fraction to decimal form, we just need to divide the numerator by the denominator.
Here the fraction is 3/4 which means we need to divide: 3 ÷ 4.
* Use the attatched images for steps*
Therefore, 3/4 = 0.75.
Thus, 3/4 is expressed as 0.75 in the decimal form.

b= 47°
Step-by-step explanation:
the value of a straight line is 180°. so create an equation that sets the angle values to equal 180°, then solve for b:
(3b-6)+(b-2)=180
3b-6+b-2=180
4b-8=180
4b=188
b=47

Step-by-step explanation:
The area of a square is any given one of the sides, squared. We can take this information and apply it to this problem. If the area is 1/49 km squared, we can take the square root of this to find the length of each side.
The square root of 1 is 1, and the square root of 49 is 7, so the answer is 1/7 km for each side.

The Super Bowl half time show lasts 30 minutes. If the half time show is 1/7 of the total game time, how many hours is the Super Bowl from start to finish? Write your answer as a mixed number.
Answers
Answer:
3 1/2 hours.
Step-by-step explanation:
If the Half Time show is one-seventh of the show and lasts for 30 minutes, we can multiply that by 7 to get the total amount of minutes.
30 x 7 = 210
To convert the number of minutes to hours, 210 can be divided by 60 to result in a total of 3.5, therefore, the Super Bowl lasts for 3 1/2 hours.

Let f(x) = StartFraction x squared minus 5 x + 4 Over x minus 1 EndFraction and g(x) = 2 Superscript x minus 3. For which value of x does f(g(x)) have a discontinuity?
Answers
9514 1404 393
Answer:
x=1
Step-by-step explanation:
The function f(x) is undefined where its denominator (x+1) is zero. That will be the case for x=-1.
The composition f(g(x)) will give f(x) an argument of -1 when g(x) = -1. That will be the case when ...
2^x -3 = -1
2^x = 2 . . . . . add 3
x = 1 . . . . . . match exponents
f(g(x)) will have a discontinuity at x = 1.

x=1

r/3 = 3
Then, you need to multiply both sides by 3 to get r alone:
r = 9
r is 9
