-2(2x+9)\ \textgreater \  -4x + 9 

-4x-18\ \textgreater \ -4x+9
 

-18\ \textgreater \ 9
 \text{Cancel -4x from  both sides} 

\text{No Solution}

-2(2x+9)>-4x+9
1)We solve this inequation:
-2(2x+9)>-4x+9
-4x-18>-4x+9
-4x+4x-18>9
-18>9  This is not true, because -18<9; Therefore this inequation is never true.

Answer: this inequation is never true.

kompoz [17]

Answer:

In a paragraph proof, statements and their justifications are written in sentences in a logical order.

A two-column proof consists of a list statements and the reasons the statements are true.

A paragraph proof is a two-column proof in sentence form.

Step-by-step explanation:

  • In a paragraph proof, statements and their justifications are written in sentences in a logical order.
  • A two-column proof consists of a list statements and the reasons the statements are true.
  • A paragraph proof is a two-column proof in sentence form.

A paragraph proof is only a two-column proof written in sentences. However, since it is easier to leave steps out when writing a paragraph proof.

A two-column geometric proof consists of a list of statements, and the reasons that we know those statements are true. The statements are listed in a column on the left, and the reasons for which the statements can be made are listed in the right column

Literal equations, please help! this one is confusing to me.
sertanlavr [38]
What is asked here is that you isolate y so that the equation takes the form of y = ..., where ... will be something that contains a, b and c but not y. So how do we get there? By applying some standard permutations to equations like so:

aby - b = c

First, we bring the -b term to the right hand side by adding b left and right:

aby -b+b = c+b

The -b and +b cancel out, so we get:

aby = c + b

Then, we divide left and right hand side by ab:

aby/ab = (c+b)/ab

Again, the ab/ab on the left cancels out (it is 1), so we get:

y = (c+b)/ab

And we're done!

So you have to know that it is allowed to add or subtract something (anything) to/from the left and right hand side of an equation. Likewise, you have to know that it is allowed to multiply or divide by something, as long as it isn't 0.

Display the set of data in a histogram.
VARVARA [1.3K]

Answer:

The answer to your question is the third histogram

Step-by-step explanation:

What we must check in a histogram is that the x-axis is represented the intervals and in the y-axis is represented the frequency.

The first histogram is incorrect just by observing the first bar, we notice that the correct frequency from 0 to 4 is 3, not 14. This histogram is incorrect.

Also, the second histogram is incorrect, the frequency of the first category is 3, not 12. This histogram is wrong.

The third histogram is correct because all the bars are in agreement with their frequencies.

The last histogram is incorrect, for example, the last frequency is 12, not 3.
