Answer:

x = 1 y =23

x = 3 y = 15

x = 5 y = 7

x = 6 y = 3

Step-by-step explanation:

what the x is saying when it says it equals 1, 3, 5, and 6 its basically saying anytime you see an x in the problem hence the y =27 - 4x you replace the x with the number that x equals for example if x = 3 I plug three in every time I see an x in the equation like the equation y = 27 - 4x so it would be y = 27 - 4(3) (parentheses meaning 4 times 3) so it would be now y = 27 - 12 and that would be y = 15 hope this helps :)

The first sentence in the chart belongs to the subjunctive mood, while the other sentences can be classified as part of the conditional mood.

<h3>What is a verb mood?</h3>

In language, the verb mood indicates the attitude of the speaker, and therefore, it provides clues about the way language is used. For example, the imperative mode indicates an order is being given.

<h3>What is the difference between the conditional and the subjunctive mood?</h3>
  • Subjunctive: It is used for expressing wishes; due to this, it is common to find the use of words such as "wish".
  • Conditional: It expresses a condition or a situation that will/can happen if another situation occurs. This can be identified due to the use of "if".

Based on this, the first sentences belongs to the subjunctive mood, while the other sentences are part of the conditional.

4. Solve the following system of equations for x.
Ber [7]

We are given the system of equations -:

\large{ \begin{cases} 2x + 3y =  - 14 \\ y = 6x + 22 \end{cases}}

Since the second equation is y-isolated equation. It can be substituted as y = 6x+22 in the first equation.

\large{2x + 3(6x + 22) =  - 14}

Expand 3 in the expression so we can combine like terms and isolate x-variable.

\large{2x + 18x + 66 =  - 14}

Then combine like terms.

\large{20x + 66 =  - 14}

Get rid of 66 from the left side by subtracting both sides by itself.

\large{20x + 66 - 66 =  - 14 - 66} \\  \large{20x =  - 80}

To finally isolate the variable, divide both sides by 20 so we can leave x only on the left side.

\large{ \frac{20x}{20}  =  \frac{ - 80}{20} }

Simplify to the simplest form.

\large{x =  - 4}

Normally, we have to find the y-value too but since we only find x-value. The answer is x = -4.

Answer

  • x = -4

I hope this helps! If you have any questions or doubts regarding my answer, explanation or system of equations, feel free to ask!

A container shaped as a rectangular prism can hold 756 wooden cube blocks with edge lengths of 13 ft.
pychu [463]

Answer:

the volume of the container is 28\ ft^{3}

Step-by-step explanation:

we know that

To find the volume of the container calculate the volume of one wooden cube block and multiply by 756

The volume of one cube is equal to

V=(1/3)^{3}= (1/27)\ ft^{3}

the volume of the container is equal to

V=(1/27)*756=28\ ft^{3}
