The weight of 8 science books is 28 pounds. What is the weight of 11 science books? The weight of 11 science books is..

Answers

Answer 1

Answer: 28 ÷ 8 = 3.5 × 11 = 38.5

Answer 2

Answer: First you need to find out how much one science book ways. to do this, you divide the weight by the number of books. 28 divided by 8. that is 3.5.

The next step is to figure out how much 11 books weigh. you take the weight of one book (3.5) and multiply it by the amount of books (11).

the answer is 38.5 pounds.

Which of the following is an odd function?

Answers

Answer:

f(x) = -x is odd

Step-by-step explanation:

A function f is odd if f(-x) = -f(x) for all x in the domain of f. Then, let's check each of the functions.

1. f(x) = x^3 + 5x^2 + x

f(-x) = (-x)^3 + 5(-x)^2 + (-x) = -x^3 + 5x^2 - x

-f(x) = -(x^3 + 5x^2 + x) = -x^3 - 5x^2 - x

Given that f(-x) ≠ -f(x). The function f is not odd.

2. f(x) = sqrt(x)

f(-x) = sqrt(-x) (Imaginary number)

-f(x) = -sqrt(x)

Given that f(-x) ≠ -f(x). The function f is not odd.

3. f(x) = x^2 + x

f(-x) = (-x)^2 -x = x^2 - x

-f(x) = -x^2 - x

Given that f(-x) ≠ -f(x). The function f is not odd.

4. f(x) = -x

f(-x) = - (-x) = x

-f(x) = -(-x) = x

Given that f(-x) = -f(x). The function f is odd.

Answer with Step-by-step explanation:

A function f is odd if:

f(-x)= -f(x) for all x in the domain of f

1. f(x)= $x^3+5x^2+x$

f(-x)= $(-x)^3+5(-x)^2-x$

= $-x^3+5x^2-x$

-f(x)= $-x^3-5x^2-x$

f(-x) ≠ -f(x)

So, function is not odd

2. f(x)=√x

f(-x)=√(-x)

= i√x

-f(x)= -√x

f(-x) ≠ -f(x)

So, function is not odd

3. f(x)= $x^2+x$

f(-x)= $(-x)^2-x$

= $x^2-x$

-f(x)= $-x^2-x$

f(-x) ≠ -f(x)

So, function is not odd

4. f(x)= -x

f(-x) = -(-x)

-f(x)=x

f(-x) = -f(x)

So, function is odd

How do i work out: 3/4-3/5

Answers

In order to add or subtract fractions, they must have the
same denominator. You need to change both of these
fractions to have the same denominator ... without changing
their values, of course.

The smallest common denominator for these fractions is 20 .

3/4 is the same amount as 15/20 .

3/5 is the same amount as 12/20 .

Now that they have the same denominator, you can do
the subtraction.

First step: Get a common denominator.

3/4:-

3*5=15
4*5=20

3/5:-

3*4=12
5*4=20

Now we can subtract easily because we have common denominators.

15/20-12/20

15-12/20

3/20

Now we have our most simple answer: 3/20

Step-by-step explanation:

On a coordinate plane, 2 straight lines are shown. The first solid line has a positive slope and goes through (0, negative 2) and (2, 0). Everything to the left of the line is shaded. The second dashed line has a negative slope and goes through (0, 2) and (4, 0). Everything below and to the left of the line is shaded. Which system of linear inequalities is represented by the graph? y > x – 2 and x – 2y < 4 y > x + 2 and x + 2y < 4 y > x – 2 and x + 2y < 4 y > x – 2 and x + 2y < –4
