Answer:

[tex]\frac{3^{n} }{3^{2(n-1)} }[/tex]

Step-by-step explanation:

3²⁻ⁿ is the simplification of  3ⁿ/9ⁿ⁻¹ in powers of 3.

An expression is combination of variables, numbers and operators.

The given expression is  3ⁿ/9ⁿ⁻¹

three power n divided by nine power n minus one.

To express to the power of 2, we have few properties of exponentials.

aˣ/aⁿ=aˣ⁻ⁿ

aˣ.aⁿ=aˣ⁺ⁿ

The given expression is

3ⁿ/9ⁿ⁻¹

3ⁿ/(3²)ⁿ⁻¹

3ⁿ/3²ⁿ⁻²

3ⁿ.3⁻²ⁿ⁺²

When bases are same then we will add the powers

3ⁿ⁻²ⁿ⁺²

3²⁻ⁿ

Hence 3²⁻ⁿ is the simplification of  3ⁿ/9ⁿ⁻¹ in powers of 3.

Answer:

x= 1 (any number greater than -10)

Step-by-step explanation:

">" this sign shows that any number greater than -10 can be x. There is no specific answer.

Answer:

The solution set of an inequality is < (less than) or > (greater than) to compare two or more numbers. Example 12 > - 10.

Step-by-step explanation:

When comparing two numbers, like 5 and 8, you probably recognize that the number 5 is less than the number 8. You probably also realize that the number 8 is greater than the number 5. In math, we use the inequality symbols < and > to compare two or more numbers.

Answer:

Infinitely Many Solutions!

Steps I used to get the answer :

1. Cancel -3x−3x on both sides.

15=11+4

2. Simplify  11+4 to  15.

15=15

3. Since both sides equal, there are infinitely many solutions.

Infinitely Many Solutions!

Done by NeighborhoodDealer.

Answer:

Step-by-step explanation:

Solve for x:

15 - 3x = 11 - 3x + 4

Subtract 4 from both sides

15 - 3x - 4 = 11 - 3x + 4 - 4

11 - 3x = 11 - 3x

This equation has infinite solutions since both sides of the equation are equal.

Answer:

an expression equivalent to f(2x) + [tex]3\frac{g(x)}{h(x)}[/tex] + 3 = 8x³ + [tex]\frac{27}{2}x[/tex] + 3

Step-by-step explanation:

As given ,

f(x) = x³ , g(x) = 9 , h(x) = 2x

Now,

f(2x) = (2x)³ = 2³.x³ = 8x³

⇒f(2x) = 8x³

Now,

[tex]\frac{g(x)}{h(x)} = \frac{9}{2x} = \frac{9}{2}x[/tex]

⇒[tex]3\frac{g(x)}{h(x)} = 3.\frac{9}{2}x = \frac{27}{2}x[/tex]

∴ we get

f(2x) + [tex]3\frac{g(x)}{h(x)}[/tex] + 3 = 8x³ + [tex]\frac{27}{2}x[/tex] + 3

Answer:

y = x/2 +4

Step-by-step explanation:

new slope = -1/-2 = 1/2

x1 = -4, y1= 2

y-y1 = m(x-x1)

y - 2 = 1/2 {x- (-4)}

y-2 = 1/2 (x+4)

y-2 = x/2 + 2

y = x/2 +2+2

y = x/2 +4

Answer:

x=-4, y=7

Step-by-step explanation:

According to the first equation, y = -4x - 9, so we can substitute y in the second equation for -4x - 9.

y = 3x + 19

-4x - 9 = 3x + 19

Add 9 to both sides

-4x = 3x + 28

Subtract 3x

-7x = 28

Divide by -7

x = -4

Plugging this into the equation, we have:

y = -4x - 9

y = -4(-4) - 9

y = 16 - 9

y = 7

Answer: 33

Step-by-step explanation:

The cubic feet needed is 54 and she already has 4.5 cubic feet of soil. This mean that she will need 49.5 more.

= 54 - 4.5

= 49.5

Since each soil bag has 1.5, the number of soil bags needed will be:

= 49.5 / 1.5.

= 33

Therefore, she'll need 33 bags

Answer:

2/3

Step-by-step explanation:

Use rise over run, (y2 - y1) / (x2 - x1)

Plug in the points, then simplify:

(y2 - y1) / (x2 - x1)

(-1 + 7) / (4 + 5)

6/9

= 2/3

So, the slope of the line is 2/3

Answer:

6 miles.

Step-by-step explanation:

To solve this problem, lets make an equation in slope-intercept form (y = mx + b)

The initial fee is $6. This is our y-intercept (b) as it is unchanging.

Our slope (m) would be $3, as it changes value per mile, which will be represented by x.

$24 was the total fare, so this is our y.

We have:

24 = 3x + 6

Subtract 6 from both sides.

24 - 6 = 3x + 6 - 6

We get:

18 = 3x

Divide by 3 on both sides.

18/3 = 3x/3

We get:

6 = x

So, Mike traveled 6 miles.

I would appreciate brainliest, if not that's ok!

Step-by-step explanation:

4*-2 + 3*-3 = -8 - 9= -17

4*1 +3*-2= 4-6= -2

-2*-2 + 3*-3= 4-9= -5

-2*1 + 3*-2= -2 -6 = -8

-4*-2+6*-3=8-18= -10

-4*1+6*-2=-4-12= -16

the result matrix is

-17 -2

-5 -8

-10 -16

Answer:

B

Step-by-step explanation:

Reflect x-axis means (x,y) becomes (x, -y)

Shrink by 1/3 means f(x) = x becomes f(x) = 1/3x

Up 4 units means f(x) = x becomes f(x)= x + 4

So lets put that together

[tex]f(x) = \sqrt{x}[/tex]

[tex]f(x) = -\sqrt{x}[/tex]

[tex]f(x) = -\frac{1}{3} \sqrt{x}[/tex]

[tex]f(x) = -\frac{1}{3} \sqrt{x} + 4[/tex]
