I want the answer to be explained for a 6th grader

Answer:

So lets isolate y

we have

-2x+3y=9

2/3x +2y=0

Im gonna do the first equation

so -2x + 3y = 9

Add 2x on both sides

3y= 9+ 2x

Now divide by 3 to isolate y

y= 3+ 2/3x

Now we can subsitute y into any eqaution (I’m gonna do the second one) to solve.

2/3x+ 2(3+ 2/3x)= 0

Solve:

2/3x+ 6 + 4/3x = 0

6/3x +6= 0

2x+6=0

2x= -4

x= -2

Now we can subsitute this for any equation.

so I’m gonna do the first equation

-2(-2)+3y=9

4+3y=9

3y= 5

y= 5/3

y= 1 2/3

Final answer:

x=-2

y= 1 2/3

Usando una función lineal, se encuentra que el pago es:

C) 46

Una funcion lineal tiene el seguiente formato:

[tex]y = ax + b[/tex]

En que:

En la gráfica, hay los puntos (0,20) y (5, 60), por eso:

La taja es dada por el cambio en y dividido por el cambio en x, o sea:

[tex]a = \frac{60 - 20}{5 - 0} = 8[/tex]

Por eso:

[tex]y = 8x + 20[/tex]

Con 3 horas y 15 minutos, el tiempo es de 3.25 horas, puesto que [tex]\frac{15}{60} = 0.25[/tex], por eso:

[tex]y = 8(3.25) + 20 = 46[/tex]

Using the principle of proportional relationship, the number of whole serving that can be made is 26.

Recall :

Total amount of aquafaba in ounces :

Amount of aquafaba required per serving of consomme :

1 serving = 6 oz

x servings = 160 oz

Cross multiply

6x = 160

Divide both sides by 6

x = 160/6

x = 26.667

Hence, the amount of whole serving that can be made is 26.

[tex]\mathsf{\: \frac{24}{35} }[/tex]

Step-by-step explanation:

Given the addition of two unlike fractions, [tex]\mathsf{\frac{2}{5} \: +\:\frac{2}{7} }[/tex] :

We could only add those two fractions if they have the same denominator.

In order to do so, we must determine their least common denominator (LCD), which happens to be 35.  

Next, perform the following mathematical operations:

[tex](\mathsf{\frac{2}{5} \:\times\frac{7}{7}}) + (\mathsf{\frac{2}{7} \:\times\frac{5}{5}})[/tex]  =  [tex]\mathsf{\frac{14}{35} \:+ \:\frac{10}{35}}[/tex]  =  [tex]\mathsf{\: \frac{24}{35} }[/tex]

Therefore, the correct answer is Option 3:  [tex]\mathsf{\: \frac{24}{35} }[/tex].

Step-by-step explanation:

Answer: 3x^3+2x+5

Step-by-step explanation:

I attached my written work but put simply take the value of x which in this case is -2 because x+2 also means x= -2. Then line up the coefficients next to -2 which should be in a box. So the coefficients 3, 6, 2, 9, and 10. Drop the first coefficient down which is 3 and multiply it by your x value. so the combo is multiply, add, drop. starting with 3 drop it down then multiply it by -2 to get -6. Then add -6 to the second coefficient which is 6 to get 0 so drop zero down. Then again multiply 0 by -2 to get 0 then add zero to 2 to get 2 then drop down 2. So continue till the end remmebr the only multiplication you are doing is against the x value which in this case is -2. at the end you should have 5 numbers left. Here we end with 3, 0, 2, 5, 0. So we want a zero as the last number which means we have no remainder. If the last number is not zero do not PANIC. just kidding but seriously though relax. Put the number over your expression x+2 so for example if the last number was 5 instead of zero DONT PANIC just finish your answer with 5/x+2. SO back to the 3, 0, 2, 5, 0. We add the corresponding x's to these numbers so [tex]3x^{3}+0x^{2} +2x+5[/tex] which also equals [tex]3x^3+2x+5[/tex]

The period it took the $7,500 investment to reach a future value of $10,650 at a compounding interest rate of 6% is 6 years.

The future value refers to the compounded value of present cash flows in the future, using an interest rate.

The future value can be determined using the future value table or formula.

We can also determine the future value using an online finance calculator, which also enables us to determine the period required to get a stated future value.

PV (Present Value) = $7,500

I/Y (Interest per year) = 6%

PMT (Periodic Payment) = $0

FV (Future Value) = $10,650

Results:

N (# of periods) = 6 years

Total Interest = $3,142.17

Thus, the period it took the $7,500 investment to reach a future value of $10,650 at a compounding interest rate of 6% is 6 years.

Step-by-step explanation:

The formula for the volume of a sphere is ...

  V = 4/3πr³

The sphere has a diameter of 18 in, so a radius of 9 in. Its volume is ...

  V = (4/3)π(9 in)³ = (4/3)729π in³ = 972π in³

The container can hold 972π in³ of water.

Answer:

y = 8/5x + (-4) or y = 8/5x -4

Step-by-step explanation:

Slope-intercept form is written like this:

            y = mx + b

The variable m, represents slope and b, represents the y-intercept.

To find slope, you have to find the rise/run or in other words, change of y over change of x.

From the look of the line, the slope has to be positive because the line is going up.

To go from the bottom point to the top, we have to go up 8 points and go to the right 5 points. Thus the slope is 8/5.

Now for the y-intercept. This part is easy. Just ask yourself this...

"Which of the two points is on the y-axis?"

In this case, it is the bottom point which is -4.

So your equation should look like this:

y = 8/5x + (-4)

   or y = 8/5x - 4 because when you have a plus sign and a minus sign, the result is negative.

Answer:

  C. quadratic function; quadratic term: 6x^2; linear term: x; constant term: −12

Step-by-step explanation:

A function is "quadratic" when the degree (exponent) of the highest-degree term is 2. The "quadratic" term is the one with degree 2.

The "linear" term is the one that has degree 1.

The "constant" term has no variable.

In the quadratic function ...

  f(x) = 6x^2 +x -12

the quadratic term is 6x^2

the linear term is x

the constant is -12

Answer:  The answer is either letter B or letter C

C. quadratic function; quadratic term: 6x2; linear term: x; constant term: −12

Step-by-step explanation:

Find the degree of the function to determine if linear.  f ( x ) =  6 x 2 + x − 12  is not a linear function

Nothing further can be done with this topic. Please check the expression entered or try another topic.  f ( x ) =  6 x 2 + x − 12

Answer:

Hello!

Judging by the question you have provided I have deduced that the correct answer is:

24 people

Step-by-step explanation:

To come across this answer I assumed that [tex]\frac{3}{8}[/tex] of the stickers are flowers, [tex]\frac{1}{8}[/tex] of the stickers are plants, and the wrest of the stickers are people.

I then realized that I could look at the equation this way:

If we already know how many stickers are not people, we can then add up the amount of stickers we know are not people, and then subtract that amount from the total amount of stickers to figure out how many left can be people!

Which in this case would be:

[tex]\frac{3}{8}[/tex] (not people)+  [tex]\frac{1}{8}[/tex] (not people) = [tex]\frac{4}{8}[/tex] stickers that are not people, or if simplified [tex]\frac{1}{2}[/tex] or half of the total number of stickers.

We now know that half of the stickers are not people, so thus we can deduce that the other half of the stickers are people.

And half of 48 is:

24

Thus,  24 stickers are people!

And the other 24 have to be flowers and plants!

The probability that the average selling price of the 35 homes will be within $2000 of the true mean is 0.5753

First, we need to find the z-score and this is expressed according to the formula;

[tex]z=\dfrac{x-\mu}{\sigma}[/tex]

x is the sample space

[tex]\mu[/tex] is the mean value

[tex]\sigma[/tex] is the standard deviation

Given the following parameters

Mean = $275,000

Standard deviation = $10,500

If the true mean is $273,000, then;

[tex]z=\dfrac{273,000-275000}{10,500} \\z = \frac{-2000}{10500}\\z= -0.1905[/tex]

If the true mean is $277,000

[tex]z=\dfrac{277,000-275000}{10,500} \\z = \frac{2000}{10500}\\z= 0.1905[/tex]

This means that the z-score is between -0.1095 and 0.1095

Pr( -0.1095 ≤ z ≤ 0.1095)

According to the z table, the probability that the average selling price of the 35 homes will be within $2000 of the true mean is 0.5753
