The list below gives the location of friends who are scuba diving together.
Marianna [84]

According to the information, it can be inferred that the correct inequality is Mallory > Eva (option D).

<h3>How to identify who is closer to the surface of the water?</h3>

To identify who is closer to the surface of the water we must read the distance that each of the characters is.

In this case, the person closest to the surface is Eva, who is 5 feet from the surface.

Now we must identify which inequality corresponds to reality. In this case the inequality that is correct is:

  • Mallory > Eva

This inequality is correct because Mallory is further from the surface than Eva.

Write both equations of the following system in the slope intercept form in order to decide how many solutions the system will h
anastassius [24]
Hi :) You don't need to get their slope-intercept form to know how many solutions this linear system has. Since there are two variable and 2 independent equations, there would be two solutions. One value each for the x and y variables. 

The answer is B.

Factor this expression completely. 5x^3 + 40y^6
Nastasia [14]

Answer:

see explanation

Step-by-step explanation:

Given

5x³ + 40y^{6} ← factor out 5 from each term

= 5(x³ + 8y^{6})

x³ + 8y^{6} ← is a sum of cubes and factors in general as

a³ + b³ = (a + b)(a² - ab + b²)

x³ + 8y^{6}

= x³ + (2y²)³ → a = x and b = 2y²

= (x + 2y²)(x² - 2xy² + 4y^{4})

Hence

5x³ + 40y^{6}

= 5(x + 2y²)(x² - 2xy² + 4y^{4}) ← in factored form
