Alenkasestr [34]3 years ago
3 0
A rational number is a number that can be made by dividing two integers. An integer is a number that doesn't have a fraction part.

1. 2.4 - rational
2. 74 - rational
3. 17.3333333… - rational
4. π -irrational
5. there is no number
6. –18 - rational
7. there is no number
8. 87.125 - rational
9. –30 - rational
10. –8.3 -rational
11. 58.25 -rational
12. 121 -rational
13. 4.5 -rational
14. 3 7/10 -rational

As you can see, most numbers are rational. But, when you come across pi or when you have a decimal that goes on forever without repeating (like some square roots), it tends to be irrational.

Find the gradient and y intercept of 3x+4y=5
noname [10]

Answer:

gradient = - \frac{3}{4} , y- intercept = \frac{5}{4}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x + 4y = 5 ( subtract 3x from both sides )

4y = - 3x + 5 ( divide terms by 4 )

y = - \frac{3}{4} x + \frac{5}{4} ← in slope- intercept form

with slope m = - \frac{3}{4} and y- intercept c = \frac{5}{4}

What is the lowest value of the range of the function
Alex Ar [27]

The lowest value of the range of the function shown in the graph is -2.

<h3>What is range of a function?</h3>

The range of a function is the set of its possible output values.

In other words, the range of a function is the complete set of all possible resulting values of the dependent variable (y), after we have substituted the domain or independent variables.

The range value are the y values of the graph shown.

Therefore, the lowest value of the range of the function shown on the graph is -2.
