Less than and equal = ≤

Greater than and equal = ≥

We have,

-x < 8

Interchange < with > and divide both sides by a negative sign.

x > -8

Thus,

x > -8 is equivalent to -x < 8.

Answer:

4x(3y + 7z) = 12xy + 28xz

Step-by-step explanation:

Factoring is the decomposition of an expression into a product of factors, which when multiplied together give the original expression.

Final answer:

The expression 12xy + 28xz can be factored using the distributive property by taking out the greatest common factor, which is 4x, resulting in the factored form 4x(3y + 7z).

Explanation:

To use the distributive property to factor the expression 12xy + 28xz, we need to find the greatest common factor (GCF) that is common to both terms. Here, the GCF for the numerical coefficients 12 and 28 is 4, and both terms have the variable x. Thus, we factor out 4x from both terms.

The factored expression is 4x(3y + 7z). We get this by dividing each term by the GCF:

For 12xy: (12xy)/(4x) = 3y

For 28xz: (28xz)/(4x) = 7z

Finally, we write the expression as the GCF multiplied by the sum of these quotients: 4x(3y + 7z).

6 is excluded

Step-by-step explanation:

The expression [tex]\frac{x}{x^2 - 6x}[/tex] can be simplified by factoring the denominator and dividing out the x term.

x² - 6x = x(x-6)

It simplifies the expression by:

[tex]\frac{x}{x(x - 6)}\\\\\frac{1}{x-6}[/tex]

The excluded value is any value which makes the denominator 0.

x - 6 = 0

x = 6

then we're really looking for the equation of a line whose slope is -3, and runs through (-5,-8)

[tex]\bf (\stackrel{x_1}{-5}~,~\stackrel{y_1}{-8})~\hspace{10em} slope = m\implies -3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-8)=-3[x-(-5)] \\\\\\ y+8=-3(x+5)\implies y+8=-3x-15\implies y=-3x-23[/tex]

Answer:

About 75% of the time, the mixture of cow manure and mashed bananas IS LIKELY to produce MORE biogas than pure cow manure on THIS local farm.

Step-by-step explanation:

(don't worry I guessed and got it correct)

In his experiment, Vector can report that bananas added to cow manure results in more energy production, as indicated by larger balloon growth. However, "he should mention that other factors may also influence the results".

Since the exact data from Vector's experiment isn't provided, I would still be able to draw a generalized conclusion based on the given situation. Vector produced bio-gas from cow manure and bananas, and the growth of balloons served as an indication of energy production. If the balloons corresponding to the banana-mixture bottles grew larger than the manure-only ones, it would imply that adding bananas creates more energy. Increased biogas production can be observed with larger circumference balloons because more gas fills up the balloon, causing it to grow larger. Thus, the experimenting student can report in Biogas Club that using a banana-enhanced biomass recipe for cow manure can potentially increase biogas production. It is, however, crucial to note that various other factors can influence gas production, and it might be beneficial to continue research and experimentation.

Answer:

50 miles per hour

Step-by-step explanation:

Here,

Time=  8 hours

Distance=400 miles

The speed is calculated by dividing the distance by time.

So,

Average Speed=Distance/Time

=  400/5

=50 miles per hour

The average speed of the Amtrak train traveling from Los Angeles to San Francisco, which is a distance of 400 miles in 8 hours, is 50 miles per hour.

The subject of this question is Mathematics, specifically involving the concept of speed which is a part of physical science and physics. To find the average speed of the Amtrak train, we need to divide the total distance traveled by the time taken for the journey. The total distance from Los Angeles to San Francisco is given as 400 miles, and the time taken is 8 hours.

To calculate the average speed, use the formula:

Average Speed = Total Distance / Total Time

Substituting the given values:

Average Speed = 400 miles / 8 hours = 50 miles/hour

Therefore, the average speed of the Amtrak train is 50 miles per hour.

To solve the data distribution problem among four devices, we use a system of equations representing the conditions given for the data storage among devices A, B, C, and D. By expressing all variables in terms of the amount on device B and solving, we determine the data distribution to be 35 GB, 70 GB, 105 GB, and 15 GB for devices A, B, C, and D respectively.

Solving the Data Distribution Problem

Let's represent the amount of data on devices A, B, C, and D as a, b, c, and d respectively. Given that the total amount of data is 225 GB, we have:

From these equations, we can express everything in terms of b and subsequently find the values of a, b, c, and d. To demonstrate, let's substitute (2) and (3) into (1) and solve for b:

Now, using equation (3), we can express d in terms of b and substitute into (5):

Substitute c from (3) into (4), and then d from (6) into the result:

Simplify (7) and solve for b:

We calculate a = 35GB, b = 70GB, c = 105GB, and d = 15GB. These are the amounts of data on devices A, B, C, and D respectively.

Devices A, B, C, and D contain approximately 9.0 GB, 18.1 GB, 157.4 GB, and 13.4 GB, respectively.

Let's denote:

- The amount of data on device A as [tex]\(x\)[/tex] GB.

- The amount of data on device B as [tex]\(y\)[/tex] GB.

- The amount of data on device C as [tex]\(z\)[/tex] GB.

- The amount of data on device D as [tex]\(w\)[/tex] GB.

Given:

1. [tex]\(x = \frac{1}{2}y\)[/tex]

2. [tex]\(z = 5(y + w)\)[/tex]

3. [tex]\(2z + 4w = 500 - y\)[/tex]

We know that the total amount of data on all devices is 225 GB:

[tex]\[x + y + z + w = 225\][/tex]

We'll use these equations to solve for [tex]\(x\), \(y\), \(z\), and \(w\)[/tex].

Substituting [tex]\(x = \frac{1}{2}y\)[/tex] into the equation for the total amount of data:

[tex]\[\frac{1}{2}y + y + z + w = 225\][/tex]

[tex]\[y + 2y + z + w = 225\][/tex]

[tex]\[3y + z + w = 225\][/tex]

[tex]\[y = \frac{225 - z - w}{3}\][/tex]

Now, we'll use this expression for [tex]\(y\)[/tex] to rewrite the other equations:

From equation 2:

[tex]\[z = 5\left(\frac{225 - z - w}{3} + w\right)\][/tex]

[tex]\[z = \frac{5}{3}(225 - z - w) + 5w\][/tex]

[tex]\[z = \frac{5}{3}(225) - \frac{5}{3}z - \frac{5}{3}w + 5w\][/tex]

[tex]\[z + \frac{5}{3}z + \frac{5}{3}w = \frac{5}{3}(225) + 5w\][/tex]

[tex]\[\frac{8}{3}z + \frac{5}{3}w = \frac{1125}{3} + \frac{15}{3}w\][/tex]

[tex]\[8z + 5w = 1125 + 15w\][/tex]

[tex]\[8z = 1125 + 10w\][/tex]

[tex]\[z = \frac{1125 + 10w}{8}\][/tex]

From equation 3:

[tex]\[2z + 4w = 500 - \frac{225 - z - w}{3}\][/tex]

[tex]\[2z + 4w = 500 - \frac{225}{3} + \frac{1}{3}z + \frac{1}{3}w\][/tex]

[tex]\[2z + \frac{1}{3}z + \frac{1}{3}w + 4w = \frac{1500 - 225}{3}\][/tex]

[tex]\[2z + \frac{1}{3}z + \frac{13}{3}w = \frac{1275}{3}\][/tex]

[tex]\[\frac{7}{3}z + \frac{13}{3}w = \frac{1275}{3}\][/tex]

[tex]\[7z + 13w = 1275\][/tex]

[tex]\[7\left(\frac{1125 + 10w}{8}\right) + 13w = 1275\][/tex]

[tex]\[7(1125 + 10w) + 104w = 10200\][/tex]

[tex]\[7875 + 70w + 104w = 10200\][/tex]

[tex]\[174w = 2325\][/tex]

[tex]\[w = \frac{2325}{174}\][/tex]

[tex]\[w = 13.4\][/tex]

Substituting [tex]\(w = 13.4\)[/tex] into the equation for [tex]\(z\)[/tex]:

[tex]\[z = \frac{1125 + 10(13.4)}{8}\][/tex]

[tex]\[z = \frac{1125 + 134}{8}\][/tex]

[tex]\[z = \frac{1259}{8}\][/tex]

[tex]\[z = 157.375\][/tex]

Substituting [tex]\(w = 13.4\)[/tex] into the expression for [tex]\(y\)[/tex]:

[tex]\[y = \frac{225 - z - w}{3}\][/tex]

[tex]\[y = \frac{225 - 157.375 - 13.4}{3}\][/tex]

[tex]\[y = \frac{54.225}{3}\][/tex]

[tex]\[y = 18.075\][/tex]

Substituting [tex]\(y = 18.075\)[/tex] into the equation for [tex]\(x\)[/tex]:

[tex]\[x = \frac{1}{2}y\][/tex]

[tex]\[x = \frac{1}{2}(18.075)\][/tex]

[tex]\[x = 9.0375\][/tex]

So, the amount of data on each device is approximately:

- Device A: [tex]\(9.0\)[/tex] GB

- Device B: [tex]\(18.1\)[/tex] GB

- Device C: [tex]\(157.4\)[/tex] GB

- Device D: [tex]\(13.4\)[/tex] GB

Step-by-step explanation: my math teacher told me

3x+6y=22 and 6x+12y=44 system of linear equations have an infinite number of solutions.

A system of linear equations will have an infinite number of solutions when the equations are the same. That is, when the equations coincide.

Let's take the system,

3x-8y=21

6x-16y=46

Divide the second equation throughout by 2:

We get 3x-8y=23, This is not the same as the first equation. This system does not have infinitely many solutions.

Let's take the system,

3x+6y=22

6x+12y=44

Divide the second equation throughout by 2:

We get 3x+6y=22, This is the same as the first equation. This system has infinitely many solutions.

Let's take the system,

Look at the picture.

The x-intercepts are where the graph crosses the x-axis, and the y-intercepts are where the graph crosses the y-axis.

Final answer:

To find the y-intercept of a line, set x to zero in the equation y = mx + b, and the y-intercept is the value of b. To find the x-intercept, set y to zero and solve for x. The intercepts are the coordinates where the line crosses respective axes.

Explanation:

To determine the intercepts of a line, you need to find the points where the line crosses the axes. The y-intercept is the point where the line crosses the y-axis, and it is found when the value of x is 0. If we have a linear equation in the form y = mx + b, the y-intercept is the value of b, which is the y-coordinate when x is zero.

To find the x-intercept, we need to find the value of x when y is zero. This can be done by setting the y-value in the equation y = mx + b to zero and solving for x. The resulting x-value will be the x-coordinate of the x-intercept.

For example, if we have a linear equation y = -2x + 3, the y-intercept occurs when x is zero, which means y = 3. So the y-intercept is (0,3). To find the x-intercept, we set y to 0 and solve for x: 0 = -2x + 3, resulting in x = 1.5. Thus, the x-intercept is (1.5,0).

Step-by-step explanation:

6(2x-1)-12=3(7x+6)

Distribute

12x -6 -12 = 21x +18

Combine like terms

12x-18 = 21x+18

Subtract 12x from each side

12x-12x-18 = 21x-12x+18

-18 = 9x+18

Subtract 18 from each side

-18-18 = 9x+18-18

-36 = 9x

Divide by 9

-36/9 = 9x/9

-4 =x

So x 2x are the sides using Pythagorean theorem x^2 + (2x)^2= 5x^2

So the side is the square root of 5x^2 so now we have the third side

The sum of the sides should add to 28 so:

X+2x+√5x=28 factor the x

X(3+√5)=28 and we know √5=2.236

So x= 28/5.236= 5.347

To find the lengths of all three sides of the right triangle, set up two equations using the given information and the Pythagorean theorem. Solve these equations to find the values of x and the lengths of the other two sides.

Let x be the length of the shorter side of the right triangle. According to the problem, the longer side is twice as long as the shorter side, so its length is 2x. The perimeter of the triangle is given as 28, so we can set up the equation x + 2x + hypotenuse = 28. Using the Pythagorean theorem, we know that the sum of the squares of the two legs is equal to the square of the hypotenuse, so we can write another equation x^2 + (2x)^2 = hypotenuse^2. Solving these two equations will give us the lengths of all three sides of the triangle.

From the perimeter equation, we have x + 2x + hypotenuse = 28. Simplifying, we get 3x + hypotenuse = 28. Rearranging, we get hypotenuse = 28 - 3x.

Substituting this into the Pythagorean theorem equation, we have x^2 + (2x)^2 = (28 - 3x)^2. Simplifying and solving this equation will give us the value of x, which we can then use to find the lengths of the other two sides of the triangle.

Substituting it into the quadratic equation to find the roots, we have:

[tex]\frac{-b+-\sqrt{b^{2}-4ac} }{2a}=\frac{-3+-\sqrt{3^{2}-4*1*-5} }{2*1}\\\\\frac{-3+-\sqrt{3^{2}-4*1*-5} }{2*1}=\frac{-3+-\sqrt{9+20} }{2}\\\\\frac{-3+-\sqrt{29}}{2}[/tex]

So,

[tex]x_{1}=\frac{-3-\sqrt{29}}{2}\\\\x_{2}=\frac{-3+\sqrt{29}}{2}[/tex]
