Answer:

[tex]a^{\frac{5}{2}} = a^{2}\sqrt{a}[/tex]

Step-by-step explanation:

Given:

Given expression is.

[tex]= a^{\frac{5}{2}}[/tex]

We need to write the given expression in radical form.

Solution:

Rewrite the expression as.

[tex]= a^{\frac{5}{2}}[/tex]

Now we extract power as [tex](a^{m})^{\frac{1}{n} }=a^{\frac{m}{n}}[/tex]

[tex]=(a^{5})^{\frac{1}{2} }[/tex]

Now we write the above expression in radical form and simplify.

[tex]=\sqrt[2]{(a^{5})}[/tex]

[tex]=\sqrt[2]{(a\times a)\times (a\times a)\times a}[/tex]

[tex]=\sqrt[2]{a^{2}\times a^{2}\times a }[/tex]

[tex]= a\times a\times \sqrt[2]{a}[/tex]

[tex]= a^{2}\times \sqrt[2]{a}[/tex]

[tex]a^{\frac{5}{2}} = a^{2}\sqrt{a}[/tex]

Therefore, the radical form of the given expression [tex]a^{\frac{5}{2}} = a^{2}\sqrt{a}[/tex]

Answer:

Step-by-step explanation:

2x + y = 5.....multiply by -3

3x - 2y = 4...multiply by 2

--------------------------

-6x - 3y = -15 (result of multiplying by -3)

6x - 4y = 8 (result of multiplying by 2)

-------------------------add

-7y = - 7 <===== here is one mistake.....its -7, not 7

y = -7/-7

y = 1

now sub 1 in for y in either of ur original equations to find x

not sure why u r multiplying again on ur paper when all u have to do is sub

2x + y = 5

2x + 1 = 5

2x = 5 - 1

2x = 4

x = 4/2

x = 2

solution is : (2,1)

the bad part about elimination is if there is a mistake made in the first part, it carries through to the end. So it is always best to check ur answers.

Step-by-step explanation:

Answer:

-3/4

Step-by-step explanation:

3x + 4y = 8....find the slope

in y = mx + b form, the slope can be found in the m position...so lets put this equation in y = mx + b form

3x + 4y = 8.....subtract 3x from both sides

4y = 8 - 3x.....now divide both sides by 4

y = 2 - 3/4x....rearrange

y = -3/4x + 2

y = mx + b

y = -3/4x + 2

as u can see, the number in the m position (the slope) = -3/4

The slope of the line represented by the equation 3x + 4y = 8 is -3/4.

The slope of a line can be determined from its equation in slope-intercept form, which is of the form y = mx + b. The coefficient of x, m, represents the slope of the line. In the given equation 3x + 4y = 8, we can rearrange it to the slope-intercept form by isolating y: 4y = -3x + 8, y = (-3/4)x + 2. Therefore, the slope of the line represented by this equation is -3/4.

[tex]g=\frac{20}{3}[/tex]

Solution:

Given expression is [tex]-3\frac{1}{3}=\frac{-1}{2}g[/tex].

To solve the given expression:

Let us first convert the mixed fraction into improper fraction.

⇒ [tex]-3\frac{1}{3}=\frac{-1}{2}g[/tex]

⇒ [tex]-\frac{(3\times 3 )+1}{3}=\frac{-1}{2}g[/tex]

⇒ [tex]-\frac{10}{3}=\frac{-1}{2}g[/tex]

Do cross multiply on both sides of the equation.

⇒ [tex]-10\times2=(-1\times3)g[/tex]

⇒ [tex]-20 = -3g[/tex]

⇒ [tex]\frac{-20}{-3}=g[/tex]

Both minus in the numerator and denominator are cancelled.

⇒ [tex]\frac{20}{3}=g[/tex]

Hence, [tex]g=\frac{20}{3}[/tex].

Answer:

Step-by-step explanation:

Using the initial value a = 16 and the common ratio r = 1/4, we can use the equation for the sum of an infinite geometric series as |r| < 1:

S = a / (1-r)

  = 16 / (1-(1/4))

  = 16 / (3/4)

  = 64/3

The sum of the series is 64/3.

A geometric sequence is one where each phrase is discovered by multiplying the term before it by the same number.

The given series is 16 + 4 + 1 +...

Note that each term of the series is 1/4 of the preceding term, therefore, the series is a geometric series with a common ratio of r = 1/4.

The sum of an infinite geometric series is:

s= a/(1-r)

s= 16/(1-1/4)

s = 64/3

Hence, the sum of the series is 64/3.

The standard form of the line is [tex]6y-x=30[/tex]

Step-by-step explanation:

The equation of the line in this problem, written in the point-slope form, is

[tex]y=\frac{1}{6}x+5[/tex] (1)

We want to rewrite it in the standard form with integers, that means in the form

[tex]ax+by=c[/tex]

where a, b and c are integer numbers.

We start by manipulating eq.(1), by multiplying both terms of the equation by 6:

[tex]6y = \frac{1}{6}x\cdot 6+5\cdot 6\\6y=x+30[/tex]

Now we subtract [tex]-x[/tex] on both sides:

Answer:

8/12 < 3/4

8/12 is less than 3/4.

The relation symbol that makes the comparison 8/12 _____ 3/4 true is '<', meaning 8/12 is less than 3/4.

The student is dealing with a mathematical comparison of fractions. They are asked to find a relation symbol to correctly fill the blank between 8/12 and 3/4. To determine the correct symbol, we need to first compare these fractions correctly.

Applying simplification, we can reduce 8/12 to 2/3. Now, we have a comparison between 2/3 and 3/4. In order to compare them, we can convert these fractions to similar denominators or we could convert them to decimals. Using that method we have 2/3 which equals to approximately 0.667, and 3/4 which equals to 0.75.

Since 0.75 > 0.667, the relation symbol that makes 8/12 relates to 3/4 is '<' (less than).

If a system a infinite solutions, that means that the lines overlap

If a system has no solutions, that means that the lines never touch, or that they are parallel

If a system has one solution, it means that the lines intersect at one point.

A system of two linear equations in two variables can have 0, 1, or infinitely many solutions. The number of solutions can be determined without graphing by comparing the slopes and y-intercepts of the equations. If the slopes are equal and y-intercepts are different, the system has no solution. If the slopes are equal and y-intercepts are equal, the system has infinitely many solutions. If the slopes are not equal, the system has exactly one solution.

One example of a system of two linear equations in two variables with 0, 1, or infinitely many solutions is:

Equation 1: 2x + 3y = 8

Equation 2: 4x + 6y = 16

To determine the number of solutions in this system without graphing, we can use the concept of slopes. If the slopes of the two lines are equal and the y-intercepts are also equal, then the system has infinitely many solutions. If the slopes are equal but the y-intercepts are different, then the system has no solution. If the slopes are not equal, then the system has exactly one solution.

In this example, both equations have the same slope of ½; however, the y-intercepts are different. Therefore, this system has no solution.

This reveals that the two lines in the graph of this system are parallel and will never intersect.

Answer:

Therefore, Equation of line and the slope is

[tex]y=-2x[/tex]

[tex]Slope = -2[/tex]

Step-by-step explanation:

Given:  

Let,  

point A( x₁ , y₁) ≡ ( 3 ,-6)

point B( x₂ , y₂ )≡ (-1 , 2)

To Find:  

Equation of Line AB =? ( Assumption)

Solution:  

Equation of a line passing through a points A( x₁ , y₁) and point B( x₂ , y₂ ) is given by the formula Two -Point Form,  

[tex](y-y_{1})=\dfrac{y_{2}-y_{1} }{x_{2}-x_{1} }\times (x-x_{1})[/tex]  

Now on substituting the slope and point A( x₁ , y₁) ≡ ( 3 , 6) and B( x₂ , y₂ )≡ (-1 , 2) we get  

[tex](y-(-6))=\dfrac{2--6}{-1-3}\times (x-3)\\\\y+6=\dfrac{8}{-4}(x-3)\\\\y+6=-2(x-3)\\y+6=-2x+6\\y=-2x[/tex] .....Required Equation of line

Which is also in the form of

[tex]y=mx[/tex] ....Also called as Equation of line Passing through Origin.

where , m =slope

Therefore, Equation of line and the slope is

[tex]y=-2x[/tex]

[tex]Slope = -2[/tex]

To find the equation of a line passing through two given points, calculate the slope using the slope formula, and then substitute the slope and one of the points into the point-slope form of a line equation. The line passing through the points (3,-6) and (-1,2) is given by the equation y = -2x + 6.

To find the equation of the line that passes through the points (3, -6) and (-1, 2), we use the formula for the slope, denoted as 'm': m = (y2 - y1) / (x2 - x1).

Then, we substitute the given pair of points into this formula to find the slope: m = (2 - -6) / (-1 - 3) = 8 / -4 = -2.

After obtaining the slope, we use the point-slope form of an equation of a line, which is y - y1 = m(x - x1). Substitute one of the given points (3, -6) and the slope -2 in: y - -6 = -2(x - 3).

Simplify this to get the final equation: y = -2x + 6.
