Exponents and power - [tex]12y^3 - 4y^3 = 8y^3[/tex]

What are exponents and power?

Exponents and powers are two techniques for simplification of extremely big or extremely small numbers. For instance, we can write 3 x 3 x 3 x 3 as [tex]3^{4}[/tex], where 4 is the exponent and 3 is the base, to demonstrate 3 x 3 x 3 x 3 in a straightforward manner. There is a claim of power throughout the entire sentence [tex]3^{4}[/tex].

How do you perform exponentiation operations?

Rule 1: All operations enclosed in parenthesis must be simplified.
Rule 2 states that all exponents should be simplified, starting from the left.
Rule 3: When multiplying and dividing, always go from left to right.
Rule 4: Always add and subtract by moving from left to right.

[tex]8y^{3}[/tex] is the correct answer to the given equation.
[tex]12y^{3} - 4z^{3}\\ = (12-4)y^{3}\\= (8)y^{3}\\ =8y^{3}[/tex]

The value of  x³(x³ - 18) if x(x - 3) = -1 is -1.

To simplify simply means to make anything easier. In mathematics, simplifying an equation, fraction, or problem means taking it and making it simpler. Calculations and problem-solving techniques simplify the issue.

We have been given that

x(x - 3) = -1 ....... eq(1)

Find out the value of

x³(x³ - 18) ........eq(2)

We first simplify the value of x in equation (1)

x(x−3)=−1

Divide by x on both side

x(x−3)/x = −1/x

(x−3)=−1 /x

Rewrite as

x + 1/x = 3

Taking cube on both sides

(x + 1/x)³ = 3³

x³ + (1/x)³ = 27 - 3×3

x³ + (1/x)³ = 27 -  9

x³ + (1/x)³ = 18

Multiply by x³

x^6 + 1 = 18x³

x^6 - 18x³ = -1

x³(x³ - 18) = -1

Hence, the value of equation x³(x³ - 18) is also -1.

Answer: 18.7598

Step-by-step explanation:

4 x 1.50= 6

6+ 3.95=9.95

3x 0.99=  2.97

2.97 + 9.95= 12.92

12.92+ 5= 17.92

6.5% of 12.92= 0.8398

6.5% of 12.92 + 17.92= 18.7598.

Answer: 70 in.

Step-by-step explanation:

So we know that the perimeter of a rectangle =2(Length*Breadth)

Given =

Area of the rectangle = 35 [tex]in.^{2}[/tex]

Length = 7 in.

Area of a rectangle = Length*Breadth

35 = 7*Breadth

[tex]\frac{35}{7}[/tex] = Breadth

5 = Breadth

Now we can find out the perimeter of the rectangle =

= 2(Length*Breadth)

= 2(7*5)

= 2*35

= 70 in.

One possible solution to the system of inequalities is (90, 50)

From the question, we have the following parameters:

Supplies = 120 tacos or burritos

This means that

x + y = 120

Where x represents the number of tacos and y represents the number of burritos

Also, we have

She must sell no less than $580

This means that

3.75x + 7.25y >= 580

So, we have the system of inequalities to be given as

x + y = 120

3.75x + 7.25y >= 580

Next, we plot the system of inequalities on a graph

See attachment for the system of inequalities on a graph

From the attached graph, we have both lines of the graph intersect at (82.857, 37.143)

When the point is moved to the shaded region, we have one of the possible points to be (90, 50)

Hence, the solution to the system of inequalities is (90, 50)

The remainder is 4297-330*13 = 7

A statement is 2 less than the quotient of a number y and 3. The algebraic expression is (y/3)-2.

Given that,

A statement is 2 less than the quotient of a number y and 3.

According to question,

An algebraic expression can be written by use of 2  less than the quotient of a number y and 3.

To evaluate an algebraic expression is to determine its value when a certain number is used in lieu of the variable. In order to evaluate an expression, we first replace the variable with the supplied number, then we streamline the expression using the order of operations.

Here, expression is (y÷3)-2=(y/3)-2.

If we substitute the values 0,1,2,3,4...

We get the values between -7 and 4.

Therefore, the algebraic expression for the statement  2 less than the quotient of a number y and 3 is written as (y/3)-2.

It will take you 45 more minutes to finish walking the remaining distance.

If you have already walked 550 ft, subtracting it to the total distance you need to walk, then the remaining distance will be:

10,000 ft - 550 ft = 9450 ft

Rate is the relationship between two quantities of different units. Rate of speed is the amount of distance over total time.

If you walk at the rate of 210 ft/min, then the time it will take you to finish the remaining distance will be:

rate = distance/time

time = distance/rate

time = 9450 ft/(210 ft/min)

time = 45 mins

Hence, it will take you 45 more minutes to finish the walk.

The composite result function of ( f ° g )(x) in the given functions f( x ) = x² + 9 and g( x ) = x² - 9 is x⁴ - 18x² + 90.

A function is simply a relationship that maps one input to one output.

Given the data in the question;

First, we set up the composite result function f(g(x)).

f( x ) = x² + 9

f( g(x) ) = f( x² - 9 ) = ( x² - 9  )² + 9

f( g(x) ) = ( x² - 9  )² + 9

Expand the parenthesis

f( g(x) ) = ( x² - 9 )( x² - 9 )  + 9

f( g(x) ) = ( x²( x² - 9 ) -9( x² - 9 ) + 9

f( g(x) ) = x⁴ - 9x² - 9x² + 81 + 9

Collect and add like terms

f( g(x) ) = x⁴ - 18x² + 81 + 9

f( g(x) ) = x⁴ - 18x² + 90

Therefore,  ( f ° g )(x) in the given functions is x⁴ - 18x² + 90.

The solution to the equations are x = 3 and no solution in the set, respectively

Question 1

The equation is given as:

5x - 6 = 9

The replacement set is given as

{0,1, 2, 3, 4}

So, we replace the variables using the elements in the replacement set

When x = 0, we have

5(0) - 6 = 9

- 6 = 9 -- false

When x = 1, we have

5(1) - 6 = 9

- 1 = 9 -- false

When x = 2, we have

5(2) - 6 = 9

4 = 9 -- false

When x = 3, we have

5(3) - 6 = 9

9 = 9 -- true

Hence, the value of the equation is x = 3

Question 1

The equation is given as:

8x + 4 = 5x - 6

The replacement set is given as

When x = 2, we have

8(2) + 4 = 5(2) - 6

20 = 4 -- false

When x = 3, we have

8(3) + 4 = 5(3) - 6

28 = 9 -- false

When x = 4, we have

8(3) + 4 = 5(4) - 6

28 = 14 -- false

When x = 5, we have

8(5) + 4 = 5(5) - 6

Step-by-step explanation:

1.  We need 2 integers (full number) when added gives us 7

this is 4 and 3

2. so the width of the rectangle is 3cm and the length is 4cm

3. to find one area of a rectangle we do

  4cmx3cm= 12[tex]cm^{2}[/tex]

4. There is 4 rectangles, so we do

      4x12[tex]cm^{2}[/tex]= 48[tex]cm^{2}[/tex]

5. so the total area of the pattern is

The pieces of candies that William gave away is 15.

The linear expression that can be used to determine the number of candies left is:

Pieces of candies left = initial pieces of candies - number of candies given out

Pieces of candies left when William gave out candies : 40 - x

Pieces of candies left when Hannah gave out candies : 70 - 3x

If they have the same pieces of candies left, the two above expressions would be equal.

40 - x = 70 - 3x

3x - x = 70 - 40

2x = 30

x = 15

Answer: 102in

Step-by-step explanation:

the rectangle in the top right corners dimensions are 3in by 4in therefore that area is 12in then moving onto the larger rectangle the dimensions at the bottom are 10in and the dimensions for the side are 9in (6+3) so the area of the larger rectangle is 90. adding the two areas together gives a total shaded area of 102in

Answer: the area of the shaded part of the figure is 102in

Step-by-step explanation:

6+3=9 (length of the sides of the figure)

10+4= 14 (length of the bottom of the figure)

9x14 = 126 (area of entire figure)

4x6= 24 (area of the white part of the figure)

126-24 = 102 (area of the shaded part of the figure)

Answer: 1

Step-by-step explanation: The reciprocal squared of an integer may be found by taking the quotient of 1 and the square of the number. A number's inverse, also known as the number that must be multiplied by in order to get 1, is referred to as the number's reciprocal.

Answer:

A is the correct answer.

The graph of the equation y = -6/7x + 2 that shows the slope and y-intercept is shown in the image attached.

y = mx + b represents the equation of a line in slope-intercept form. In y  mx + b, we have the following parameters of the line it represents:

Given the equation of a line in slope-intercept form as y = -6/7x + 2, it means that the graph of the line you are to plot would have a negative slope (m) of -6/7, and must intercept the y-axis at y = 2.

So, to draw the line of the equation that was given in slope-intercept form as y = -6/7x + 2, you have to use a slope of -6/7 that show the steepness of the line, and a y-intercept of 2, that shows where the line intercepts the y-axis of the graph at y = 2, of which the corresponding x-coordinate must be equal to zero.

Therefore, the graph of y = -6/7x + 2 is shown below.
