(2) 15 : 6 → ( not 100 : 60) ← divide both parts by 3

(3) 5 : 2 ← divide both parts by 2

Which monomial is a perfect cube?

neonofarm [45]

Answer:

Option (a) is correct.

$1x^3$ is a perfect cube.

Step-by-step explanation:

Given : Some Monomial

We have to choose out of given monomial that is a perfect cube.

Perfect cubes are numbers that can be written as $(ab)^3$

So, consider $1x^3$ , we know 1 can be written as $1^3$

Thus, $1x^3$ can be written as $1^3x^3=(1x)^3$

Thus, Option (a) is correct.

The larger of two numbers is eight more than twice the smaller. The sum of the numbers is 10 less than three times the larger. F

Alinara [238K]

Answer:

-2 and 4

Step-by-step explanation:

Let's set the larger number to x, and the smaller to y. With these, we can set up our equations.

x = 2y + 8

x + y = 3x - 10

Now, we put the value of x into the second equation.

2y + 8 + y = 3(2y + 8) - 10

Now we can solve for y

3y + 8 = 6y + 24 - 10

3y + 8 = 6y + 14

8 = 3y + 14

-6 = 3y

-2 = y

Now that we have the smaller number, we can put it into the first equation and solve for the larger.

x = 2*-2 + 8

x = -4 + 8

x = 4

So your two numbers are -2 and 4.

How would I turn 8x- 4y = 16 into y=mx+b form

ivolga24 [154]

Answer: y=2x-4

Step-by-step explanation:

8x-4y=16 subtract 8x from both sides

-4y=-8x+16 now divide -4 by both sides

y=2x-4

HELP PLEASE!! Which of the following best describes the graph below? A. it us a one-to-one function B. it us a function but it i

masha68 [24]

The correct statement regarding the function $y = \sqrt{x + 2}$ is given by:

A. it us a one-to-one function.

<h3>What is the missing information?</h3>

This problem is incomplete, but researching it on the internet, the function used is $y = \sqrt{x + 2}$ .

<h3>Is it a function?</h3>

For $y = \sqrt{x + 2}$ , each value of x is associated with only one value of y, that is, the graph has <u>no vertically aligned points</u>, hence it is a function.

<h3>Is the function one-to-one?</h3>

Each value of y is also associated with only one value of x, that is, the graph has <u>no horizontally aligned points</u>, hence it is a one-to-one function, and the correct statement is given by:

A. it us a one-to-one function.
