Answer:

Step-by-step explanation:

first the parenthesis

3^4/3^0=3^4

anything raised to the power of 0 is 1

(3^4)^2=3^8     you multiply the powers

3^-6 * 3^8= 3^(-6+8)=3^2

Thhe simplified form of the expression is 9

Indices are expressed as power or exponent which is raised to a number or a variable.

According to the law of indices

[tex]a^n \times a^m = a^{n+m}\\a^n \div a^m = a^{n-m}[/tex]

Given the expression

[tex]3^{-6} \times (\dfrac{3^4}{3^0} )^2[/tex]

This can also be expressed as:

[tex]=\dfrac{1}{3^6} \times (\frac{3^4}{1})^2 \ (3^0 =1)\\= \dfrac{1}{3^6} \times 3^8\\=\dfrac{3^8}{3^6}\\=3^{8-6}\\=3^2\\=9\\[/tex]

This shows that the simplified form of the expression is 9

Answer:

Therefore, the width of the canyon is 109.09 meters.

Step-by-step explanation:

* 160/22 = k (Scale Factor)

  7.2727 = k

* Let x be the width of the canyon

 x / 15 = k

 x / 15 = 7.2727

 x = 7.2727 (15)

 x = 109.09 m

The width of the canyon is 109.09m.

Here we assume x be the width of the canyon.

The k(Scale factor) should be

= [tex]160 \div 22[/tex]

k =  7.2727  

So,

[tex]x \div 15 = k\\\\ x \div 15 = 7.2727[/tex]

 x = 109.09 m

Answer:

Step 2 contains error in the given problem.

Step-by-step explanation:

Given expression is:

[tex]\frac{1}{2}x-3=\frac{1}{3}x+6[/tex]

Step 1: identifying the LCM.

The LCM identified is 6.

This step is correct.

In the next step, we multiply the LCM with each term of the equation.

Step 2:

[tex]\frac{6}{1}(\frac{1}{2}x) -3 =\frac{6}{1}(\frac{1}{3}x)+6[/tex]

However,

In the given solution, the LCM is not multiplied with each term.

Hence,

Step 2 contains error in the given problem.

Answer:

a + b = 50 (Two numbers total 50)

b = a - 6 (one number is 6 less than the other)

Since we have a value, we can use the substitution metod:

a + a - 6 = 50

Simplify:

2a - 6 = 50

From here, you should know how to isolate a variable--add 6 then divide by 2 in this case. That'll give you a, and you'll be able to use that to solve for b.

2(a) -6= 50

2a-6= 50

six goes and adds to 50 on the other side

2a = 56

divide both sides by 2

a= 28

final answer 28

x = undefined

Step-by-step explanation:

Because you have an x and then remove the x the it is not pssible to tell what x was with the given information causing it to be undefined.

Answer:

x = 2

Step-by-step explanation:

Given

3(x - 4) = 2(- 2x + 1) ← distribute parenthesis on both sides

3x - 12 = - 4x + 2 ( add 4x to both sides )

7x - 12 = 2 ( add 12 to both sides )

7x = 14 ( divide both sides by 7 )

x = 2

Answer: 2=x

Step-by-step explanation:

3(x-4)=2(-2x+1) <- multiply number outside of parentheses by numbers inside parentheses

1)3x-12=-4x+2

2)-3x      -3x <- subtract -3x

-12=-7x+2 <- what you should have after

3)-2      -2 <- subtract 2

-14=-7x <- what you should have after

4)/-7 /-7 <- divide by -7

2=x <- what you should have after

/= divide

remember: negative multiplied by a negative equals a positive, and a negative multiplied by a positive equals a negative.

The equation of the line in the slope-intercept form will be:

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where  

From the attached graph, taking two points

Finding the slope between (0, 0) and (-10, 70)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(-10,\:70\right)[/tex]

[tex]m=\frac{70-0}{-10-0}[/tex]

[tex]m=-7[/tex]

Determining the y-intercept:

We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

From the graph, it is clear that:

at x = 0, y = 0

Thus, the y-intercept b = 0

Now, substituting m = -7 and b = 0 in the slope-intercept form

y = mx+b

y = -7x + 0

y = -7x

Therefore, the the equation of the line in slope-intercept form will be:

Answer:

2.25 ft

Step-by-step explanation:

Perimter= 28ft

W= x ft

L= 3x+5

but

P=2L+2W

substitute

28=2*(3x+5)+2x

28=6x+10+2x

collet like terms

28=8x+10

28-10= 8x

18=8x

divide both sides by 8

x= 18/8

x=2.25 ft

Hence the width is 2.25 ft
