The final expression of the simplified version is 28x + 8y + 2.

We know that, to simplify means to obtain the lowest possible form of the of the expression. The expression is written in its simplest form  when there are no more ambiguities left in the way that it is written.

Given the expression;

-2(3x + 12y - 5 - 17x - 16y + 4)

We can now expand the expression to have;

-6x - 24y + 10 + 34x + 32y - 8

This could further simplify to

Let's use the variable x to represent the price of the television set before taxes.

If the tax rate is 4%, then the original price is multiplied by 1.04, so it is equal 1.04x.

The final price is $520, so we have:

So the price before taxes is $500.00.

Answer:

arc RPQ = 305°

Step-by-step explanation:

• the angle at the centre is equal to the measure of the arc that subtends it.

arc RP = ∠ ROP = 125°

∠ QOS and ∠ ROP are vertically opposite angles and are congruent, so

∠ QOS = 125° and so arc SQ = 125°

RS is a straight angle , then

∠ POS = 180° - 125° = 55°

arc PS = 55° ( arc subtending the angle at centre

Then

arc RPQ = RP + PS + SQ = 125° + 55° + 125° = 305°

There is a 0.0003 chance that the sample mean was 18.2 ounces or more if the actual mean is 18 ounces.

So, let Y be a random variable with box weights.

These are the sample size and mean:

N's standard deviation is then roughly followed by Y ( μ = 18, SD = 0.32).

Z score is displayed as:

Where z has a mean of 0 and a standard deviation of 1 and is a normal standard variable.

Given that the standard deviation is given and that sample size n is 30. y roughly follows the Normal distribution.

If the sample mean was 18.2 ounces or more and the actual mean was 18 ounces, the probability that this was the case is given as:

[tex]\begin{aligned}&P[Y \geq 18.2]=P\left[\frac{\sqrt{n(y-u)}}{S D} \geq \frac{\sqrt{30}(18.2-18)}{0.32}\right. \\&=P\left[z \geq \frac{\sqrt{30}+0.2}{0.32}\right] \\&=P\left[z \geq \frac{1.0954}{0.32}\right] \\&=P[z \geq 3.4233] \\&=0.0003\end{aligned}[/tex]

-10x - 29 = -18x + 91

x = 15

Step-by-step explanation:

29 less than -10 times a number is equal to -18 times the number plus 91:

-10x - 29 = -18x + 91

add 21 to both sides:

-10x - 29 + 29 = -18x + 91 + 29

-10x  = -18x + 120

add 18x to both sides:

-10x + 18x  = -18x + 120 + 18x

8x = 120

divide both sides by 8:

8x/8 = 120/8

The equation of a line that is parallel to line y=3x+5 and goes through the point (6,-7) is y = 3x + 2

A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system. The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line. Any line's equation can be used to determine whether a given point is on the line or not.A linear equation with a degree of one is the equation for a line.

Given that : the equation of a line is parallel to line y=3x+5 and goes through the point (6,-7)

y=3x+5 is the equation for the given line.

This type of line is called a slope intercept. The line has a slope of m=3.

The slope of parallel lines is equal. As a result, all lines with slope m=3 will be perpendicular to one another.

y=3x+2 is an example of a line that is parallel to the supplied line.

Since the situation can be since as an  arithmetic sequence, her salary after 3 years is $73,000. After t years, her salary is a function of t, that is a(t) = 64000 + 3000 t

The given situation can be seen as an arithmetic sequence. The nth term of an arithmetic sequence is given by the formula:

a(n) = a(1) + (n - 1) . d

Where:

a(1) = the first term

d = the common difference.

The problem can be translated into an  arithmetic sequence with:

a(1) = $67000

d = $3000

Kylie's salary after 3 years is a(3),

a(3) = a(1) + (3 - 1) . d

a(3) = Kylie's salary  + 2 . 3000 = 73000

Hence, after 3 years, Kylie's salary is $73,000

Her salary after t years, means n = t. Therefore,

a(t) = a(1) + (t - 1) . d

a(t) = 67000 + (t -1) . 3000

a(t) = 64000 + 3000 t

Our function is a parabola, therefore, it has only one critical point which is its vertex. Since the coefficient of the squared term is negative, the vertex is the maximum point.The critical points of a function are given by the zeros of the first derivative. The first derivative of our function is:

The solutions for the following equation are the critical points of the original function:

The maximum point happens at x = - 3.

To find the corresponding value, we just have to evaluate x = - 3 into our function:

The maximum value of the function is 1, and it occurs at x = - 3.

Answer: The function has a maximum value

               The function's maximum value is 1

               The function's maximum value occurs at x=-3

Step-by-step explanation:

Given equation: [tex]g(x) = -3x^ - 18x - 26[/tex]

We shall use the differentiation method to find the answer.

Differentiating the equation, we get   [tex]g'(x) = - 6x - 18[/tex]

equating g'(x) = 0,

[tex]-6x - 18 = 0\\-6x = 18 \\x = -3[/tex]

Hence the minimum/ maximum value of the function lies in x = -3

on equating x>-3, g'(x) is negative

on equating x<-3, g'(x) is positive

this proves that first, the function was increasing and after x = -3, the function started to decrease hence at x=-3, the function g(x) was at its maximum value

The function's maximum value at x=-3 is

[tex]g(x) = -3x^2 - 18x - 26\\g(-3) = -3(-3)^2 - 18(-3) - 26\\g(-3) = -3(9) +54 -26\\g(-3) = 54 - 27 -26\\g(-3) = 1[/tex]

Answer:

£75 > £70 Therefore Sally is wrong.

Step-by-step explanation:

1. First we need to find the volume of the sand pit  

     60x40x100= 24,000[tex]cm^{3\\[/tex]

 Volume= 24,000[tex]cm^{3\\[/tex]

2. We need to convert 8 liters to [tex]cm^{3\\[/tex] so, all the units are the same

     1 liter= 1,000[tex]cm^{3\\[/tex]

     8 liters= 8,000[tex]cm^{3\\[/tex]

3. We then do 24,000[tex]cm^{3\\[/tex] divide by 8,000[tex]cm^{3\\[/tex] to see how many bags, we need

    24,000[tex]cm^{3\\[/tex]/ 8,000[tex]cm^{3\\[/tex] = 30

so, Sally needs 30 bags

4. We know one bag cost £2.50 to know how much 30 bags cost we do

   £2.50 x 30 = £75

so, we know 30 bags cost £75

5. Sally statement was said that it would cost less than £70 which is false as it costs £75

6. Therefore the final answer is £75>£70 so Sally is wrong.

The slope of AB = 2

The slope of CD = 2

Both lines are parallel lines.

The lines that are perpendicular to each other have slope values that are negative reciprocal of each other.

For example, if the a line's slope is a, the line that is perpendicular to it will have a slope of -1/a. This is because the negative reciprocal of a is -1/a, and (a)(-1/a) = -1.

On the other hand, the lines that are parallel to each other will have the same slope value.

Given the following:

A(−6 , −9)

B(8, 19)

C(0, −4)

D(2, 0)

Find the slope (m) of AB:

Slope of AB = (19 -(-9))/(8 -(-6))

Slope of AB = 28/14

Slope of AB = 2

Find the slope (m) of CD:

Slope of CD = (0 -(-4))/(2 - 0)

Slope of CD = 4/2

Slope of CD = 2

The graph of both lines are shown below.

Thus, the slope of AB and CD are the same, therefore, we can conclude that lines AB and CD are parallel to each other.
