Answer with explanation:

Mathematically , john's statement is wrong which is:→ if one side of an inequality is 0, you  don’t have to reverse the inequality symbol when you multiply or divide  both sides by a negative number.

Counterexample :Consider an example

→ 4x  ≥ 0, where x is a positive integer.

If we multiply or divide both sides by , -1, the inequality would result into

→ -4x ≤ 0

This transformed inequality is valid only when ,x is a Positive Integer.Here after multiplying by negative integer ,if we will not change the inequality sign, it will be an invalid Inequality.

He may be wrong. If he was wrong, this is the example. 

0 < -10x

If we were to divide both sides by -10, even though the answer would be undefined or just end up as zero, it is just a common rule to always flip the sign whenever you divide or multiply by a negative. 

Don't quote me on it, but I think I'm right.

Hope this helped!

Consider the function given by the graph. What are these values?
Natalija [7]
As you see in the picture, there are two lines that could maybe represent two linear functions. However, this is not true because of the solid point and the hollow point. This is an inequality equation that has points of discontinuity.

Points of discontinuity are breaks in the graph that are a result of an undefined point when the f(x) is substituted with a point of x that is not part of the solution. So, technically, the graph is made from one rational expression.

So, when it says f(-2), this is the y-value at x=-2. That means f(-2)=2, f(0)=3 and f(4)=-1. Specifically, there are two points at x=0, but we take the solid point only.

There were 200 melons in a box and they were distributed to 3 children in the ratio of 4:3:3. The first child sold the melons at
Elena L [17]

Answer:

$460

Step-by-step explanation:

let the number of melons be x

4x + 3x + 3x = 200 melons

10x = 200 so, x will be 20

4x = 80 melons

3x = 60

3x = 60

amount made by 1st child = 80 × $2 = 160$

the remaining melons are 60 + 60 = 120

amount collected: they sold them in groups of 2 and each group was $5. so,

120÷2 × $5 = $300

total amount = 300 + 160 = $460.
