15. Identify the slope of the line below and state the equation of the line.

mamaluj [8]

Answer:

Slope: m = 0

Equation: y = 3

Step-by-step explanation:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope.

We choose two points which the equation crosses.

I am going to choose (0,3) and (1,3)

(0,3)

When x = 0, y = 3. So

$y = mx + b$

$3 = 0m + b$

$b = 3$

(1,3)

When x = 1, y = 3. So

$y = mx + 3$

$3 = 1m + 3$

$m = 0$

Slope: m = 0

Equation: y = 3

Prove that the Greatest Integer Function f: R -> R given by f(x) = [x], is neither one-once nor onto, where [x] denotes the g

Karo-lina-s [1.5K]

F: R → R is given by, f(x) = [x]
It is seen that f(1.2) = [1.2] = 1, f(1.9) = [1.9] = 1
So, f(1.2) = f(1.9), but 1.2 ≠ 1.9
f is not one-one

Now, consider 0.7 ε R
It is known that f(x) = [x] is always an integer. Thus, there does not exist any element x ε R such that f(x) = 0.7

So, f is not onto
Hence, the greatest integer function is neither one-one nor onto.

The answer was quite complicated but I hope it will help you.

If 48% of the students in a certain college are female and there are 1440 female students, what is the total number of students

Andrews [41]

Answer:

3000 students

Step-by-step explanation:

If 48% of the students are female, and there are 1440 female students, we can set up a percentage proportion, assuming x is the total amount of students.

$\frac{1440}{x} = \frac{48}{100}$
