Hey!

Alright, according to P.E.M.D.A.S., the first step to solving this expression is to distribute.

Original Expression :

[tex]\displaystyle\ -8y^{3} (7y^{2} -4y-1)[/tex]

New Expression {Distributed Old Expression} :

[tex]\displaystyle\ -(56y^{5} -32y^{4} -8y^{3} )[/tex]

Now all you have to do is simplify the parenthesis.

Old Expression :

[tex]\displaystyle\ -(56y^{5} -32y^{4} -8y^{3} )[/tex]

New Expression {Simplified} :

Solution :

Given expression [tex]-8y^{3}(7y^{2}-4y-1)[/tex]

To simplify this expression, first we need to know about the Distributive property.

Distributive Property: [tex]a\times(b+c+d)=(a\times b)+(a\times c)+(a\times d)[/tex]

Given expression [tex]-8y^{3}(7y^{2}-4y-1)[/tex]

Applying Distributive property on this expression:

[tex]\Rigtharrow -8y^{3}(7y^{2}-4y-1)=((-8y^{3})\times7y^{2})+((-8y^{3})\times(-4y))+((-8y^{3})\times(-1))[/tex]

                           [tex]= -56y^{5}+32y^{4}+8y^{3}[/tex]

Hence, the simplified form of the expression  [tex]-8y^{3}(7y^{2}-4y-1)[/tex] is  [tex]-56y^{5}+32y^{4}+8y^{3}[/tex].

a theater has 144 seats. the theater sells tickets for $6 per adult and $4 per child

Let x be the number of adult tickets

and y be the number of child tickets

Total number of tickets sold is 144

x + y = 144  -----------> equation 1

the theater sells tickets for $6 per adult and $4 per child and earned $660

6x + 4y = 660  ----------> equation 2

Solve for x  and y

x + y = 144

y = 144 - x

Now plug it in second equation

6x + 4y = 660

6x + 4(144 - x) = 660

6x + 576 -4x = 660 (combine like terms)

2x + 576 = 660 (subtract 576 from both sides)

2x = 84 (divide by 2)

x= 42

Number of adult tickets = 42

y = 144 - x

y = 144- 42= 102

Number of child tickets = 102

The theater sold 42 adult tickets and 102 child tickets on Friday night, calculated by setting up and solving a system of equations based on the total seats and revenue.

To solve the problem, we need to set up a system of equations based on the information provided. The total number of seats is 144, and the total revenue from selling out on Friday night is $660. Let A represent the number of adult tickets sold and C represent the number of child tickets sold. Therefore we have the following equations:

Now we can solve this system of equations. Multiplying the first equation by 4, we get 4A + 4C = 576. Subtracting this from the second equation cancels out the C, leaving us with 2A = 84, or A = 42. Plugging this into the first equation gives us C = 144 - 42, or C = 102.

Therefore, the theater sold 42 adult tickets and 102 child tickets on Friday night.

x = [tex]\frac{14}{3}[/tex]

distribute parenthesis on left side and simplify

4x + 8x - 24 = 4 + 6x

12x - 24 = 4 + 6x ( subtract 6x from both sides )

6x - 24 = 4 ( add 24 to both sides )

6x = 28 ( divide both sides by 6 )

x = [tex]\frac{28}{6}[/tex] = [tex]\frac{14}{3}[/tex]

Compensation is the process of reformulating an addition, subtraction, multiplication, or division problem to one that can be computed more easily mentally.

We will use compensation to find the difference of 30,000 and 6985.

Since, we have to evaluate 30,000 - 6,985

Let us add '15' to 6985,

6,985 + 15 = 7,000

Let us add '15' to 30,000

30,000 + 15 = 30,015

Now, we have to subtract 30,015  and 7,000

= 30,015 - 7,000

= 23,015

Therefore, the difference of 6,985 from 30,000 is 23,015.

The strategy of compensation involves adjusting numbers to make calculations easier. In the case of finding the difference between 30000 and 6985, you would adjust 6985 to 7000, subtract it from 30000 to get 23000, then add back the 15 you added to 6985 at the beginning. The result is 23015.

In mathematics, compensation is a strategy where you adjust one of the numbers to make the equation easier to solve. Pivotally, you make the same adjustment to the other number so as not to change the overall result.

Let's use this strategy to find the difference between 30000 and 6985

So, through the use of compensation the difference between 30000 and 6985 is 23015.

I'm pretty sure the answer is 5/16

The answer is D

This is because if for every $50 he saves $5, and he has saved a total of $500, you can set up a proportion to find out how much money he has saved at that point.

The proportion is as follows:

50/5 == 500/x

x is equivalent to the amount of money he has saved

You can cross multiply to get the following equation:

50x == 2500

To isolate x, you must divide both sides by 50, giving you an answer of:

x = 50

This is the same as option D

A: For this equation you would use distributive property leading you to multiply 3x and 2 by 4 giving you a new expression. 12x + 8 - 2. After this you would just simplify the equation by subtracting 2 from 8 giving you 6. This leading to a new equation, 12x + 6.

B: In order to factor the expression you would need to do the reverse of distributive property, finding the GCF, or greatest common factor between the 16 and the 20b. When you do this you result in getting 4 as your GCF. Afterwards you need to divided the numbers by the GCF. Leading you to get 4(5b-4). This is how you would factor the equation.

The first quartile is the middle of the first half.

To find out how much she earned per hour you want to divide.

$66.70/9.2 = $7.25

Susie earned $7.25 per hour.

Hope this Helps!!

Susie earns $7.25 per hour.

To determine how much Susie earns per hour, you need to divide her total earnings by the number of hours worked. Given that Susie earned $66.70 in 9.2 hours, you can calculate her hourly rate as follows:

Hourly Rate = Total Earnings / Hours Worked

Hourly Rate = $66.70 / 9.2 hours

Hourly Rate = $7.25 per hour (rounded to two decimal places)

Thus, Susie earns $7.25 per hour.

Answer:

16 lines of symmetry.

Step-by-step explanation:

D is your answer!

Hope this helps!!

Option D is correct, 16  lines of symmetry does a regular polygon with 16 sides have.

a polygon is a plane figure made up of line segments connected to form a closed polygonal chain.

Apothem for a regular polygon is a line segment that originates from the center of the regular polygon and touches the mid of one of the sides of the regular polygon.

It is perpendicular to the regular polygon's side it touches.

Regular polygons have all sides the same and that apothem bisects the side in two parts, (provable by symmetry).

A regular polygon with 16 sides has a line of symmetry.

It has 16 lines of symmetry as well.

Hence, 16  lines of symmetry does a regular polygon with 16 sides have.

Answer :

The profit at point (0,5) is, 400

The profit at point (1,12) is, 1010

The profit at point (4,10) is, 1000

Step-by-step explanation :

Coordinates : It is a set of values which show an exact position on a graph.

There are two variables or coordinates that are x-coordinate and y-coordinate.

As we are given that function:

[tex]P=50x+80y[/tex]

where,

P = profit

x and y are the coordinates.

(1) Now we have to calculate the profit at point (0,5).

[tex]P=50x+80y[/tex]

x = 0 and y = 5

[tex]P=50\times 0+80\times 5[/tex]

[tex]P=0+400[/tex]

[tex]P=400[/tex]

The profit at point (0,5) is, 400

(2) Now we have to calculate the profit at point (1,12).

[tex]P=50x+80y[/tex]

x = 1 and y = 12

[tex]P=50\times 1+80\times 12[/tex]

[tex]P=50+960[/tex]

[tex]P=1010[/tex]

The profit at point (1,12) is, 1010

(3) Now we have to calculate the profit at point (4,10).

[tex]P=50x+80y[/tex]

x = 4 and y = 10

[tex]P=50\times 4+80\times 10[/tex]

[tex]P=200+800[/tex]

[tex]P=1000[/tex]

Answer:

1) point-slope form

2) slope intercept form

Explanation:

1) y−b=m(x−a)

m = slope

(a, b) A point that the line passes through

2) y=mx+b

m = slope

b = y-intercept

The required difference between slope intercept form and point-slope form line is when we have slope and y-intercept we use slope-intercept equation and when we have coordinates of a point on the line we use the point-slope form of the line.

The slope of the line is the tangent angle made by the line with horizontal. i.e. m =tanx where x in degrees.

The slope-intercept form of the equation of a line is,

y =  mx +c   - - - - - - (1)

The point-slope form of the line is given by,

(y - y1) = m(x - x1)    - - - - - - (2)
where m is the slope of equation and m = (y2 - y1) / (x2 - x 1).

Thus, we use a slope-intercept form of the equation when we have given the slope of the line and y-intercept of the line. when we have a coordinate of one point and slope or more than two coordinates of points on the line so we use the point-slope form of the equation.

Given: the water temperature at the beach started at 82 degrees and it is rising 0.6 degrees each hour

To Find: If the water temperature is now 85 degrees write and solve an equation to find h, the number of hours that have passed

Solution:

Current water temperature at beach [tex]=82^{\circ}[/tex]

temperature rising rate degrees per hour [tex]=0.6^{\circ}[/tex]

let [tex]\text{h}[/tex] be the hours passed.

water temperature at the beach after hour [tex]\text{h}[/tex] be

                                                                       [tex]= 82+0.6\text{h}[/tex]

Therefore,

equation for water temperature after [tex]\text{h}[/tex] [tex]\text{hour}[/tex] is

                    [tex]= 82+0.6\text{h}[/tex]

When water temperature is [tex]85^{\circ}[/tex]

                    [tex]85=82+0.6\text{h}[/tex]

                    [tex]0.6\text{h}=85-82[/tex]

                    [tex]0.6\text{h}=3[/tex]

                    [tex]\text{h}=\frac{3}{0.6}[/tex]

                    [tex]\text{h}=5[/tex] [tex]\text{hours}[/tex]

therefore it will take  [tex]5[/tex] [tex]\text{hours}[/tex] to reach temperature [tex]85^{\circ}[/tex]

Initial temperature = 82°

Rate of temperature rise = 0.6° per hour

Final temperature = 85°

The equation which describes the relationship :

Final temperature = Initial temperature + (rate × number of hours)

Number of hours = h

Mathematically, the relationship can be written as :

85 = 82 + 0.6h

Solving for h :

Subtract 82 from both sides :

85 - 82 = 0.6h

3 = 0.6h

Divide both sides by 0.6

3/0.6 = h

h = 5

Final answer:

To solve b(x) = 8x when b(x) = -56, we set 8x = -56, divide both sides by 8, and get x = -7. No other solutions are necessary, as the given equations are not quadratic but linear.

Explanation:

The problem involves an equation b(x) = 8x and the value b(x) = -56. We need to set these equal to each other to find the value of x that satisfies both conditions. So we have the equation 8x = -56. To solve this, we divide both sides of the equation by 8, giving us x = -7.

To check for other potential solutions, let's consider that b in the quadratic equation ax² + bx + c = 0 may be set to zero. For our equation, b does not appear to be zero, but if it were, we could simplify the equation by factoring out an x.

If the equation were in the form ax² = -c, we could solve for x by taking the square root of -c/a after moving c to the other side and dividing by a. However, in our current problem, this is not necessary since we don't have a quadratic equation but a simple linear one.

We can see that it is a quadratic equation.

Hence it is non linear.

The rate is dependent on x, so it does not have a constant rate of change  also.

We can check this :

At x= 0, y = 64

At x=1, y = [tex]-16+48+64=96[/tex]

Hence, the function does not have a constant rate of change.
