A.42
B.28
C.32
D.36

Answer:

Step-by-step explanation:

-11x - 72 = 84 + x

combine like terms on opposite side of =

(-11x )+ (-1x) = (84) + (72)

-12x = 156

divide both sides by -12 to isolate x

-12/-12 = 156/-12

x = -13

insert (-13)  for x

(-11 * -13) -72 = 84 + (-13)

71                =          71

equality means its right

Answer:

g(x)

Step-by-step explanation:

y-intersect for h(x) is -11 as shown in the table, where the x value is 0

y-intersect for f(x) you find out by subbing 0 in the place of x and get the y intersect value of 2.99

y-intersect of g(x) is 3 as shown in the drawing

as seen across the three y-intersects, the value of g(x) y-intesect is the greatest

Answer:

The answer is 6 rides that cost $26.

Step-by-step explanation:

Plan A: $20 plus $1 per ride.

Plan B: $8 plus $3 per ride.

Turn that into a linear equation to graph.

Plan A: [tex]y=1x + 20[/tex]

Plan B: [tex]y=3x + 8[/tex]

The x-axis is rides and the y-axis is $.

On the graph appears that it takes 6 rides for Plan A and B to be the same a cost of $26.

The experimental and theoretical probability for each result are:

                                    Theoretical  Experimental

P(5)                                      1/6              7/40

P( 1 or 6)                               1/3              7/20

P(no more than 4)                2/3             21/40

P(greater than 2)                  2/3                7/10

Probability determines the chances that an event would happen. Experimental probability is the probability of an event happening based on the result of an experiment that has been carried out multiples time.

Theoretical probabilities:

P(5) = number of sides with 5 / total number of sides = 1/6

P( 1 or 6)  = number of sides with 1 / total number of sides + number of sides with 6 / total number of sides  = 1/6 + 1/6 = 1/3                  

P(no more than 4)   = number of sides that is no more than 4 / total number of sides  = 4/6 = 2/3

P(greater than 2) = number of sides greater tha 2 / total number of sides   = 4/6 = 2/3      

Experimental probabilities:

P(5) =  number of times there was a result of 5 / total number of times the die was rolled = 7/40

P( 1 or 6) = (number of times there was a result of 1 / total number of times the die was rolled) + (number of times there was a result of 6 / total number of times the die was rolled )

2/40 + 12/40 = 14/40 = 7/20    

P(no more than 4) = sum of results no more than 4 / total number of times the die was rolled = ( 2 + 10 + 5 + 4) = 21/40

P(greater than 2) = sum of results greater than 2 / total number of times the die was rolled = (7 + 12 +5 + 4) / 40 = 28/40 = 14/20

Question 3: The mean would change because if you are adding new numbers you have to recount the mean meaning there is now a new average.

For the given absolute value function, we have that:

y > 0 in the intervals (-∞, -3) and (-1, ∞)

y < 0 in the interval (-3, -1)

y = 0 for x = -3 and x = -1.

When the function is positive?

The function is positive when the graph is above the horizontal axis.

Here, we can see that the intervals where the graph is above the horizontal axis is are (-∞, -3) and (-1, ∞)

When the function is negative?

The function is negative when the graph is below the horizontal axis. In this case, we can see that the only negative interval is (-3, -1)

When the function is zero?

The function is equal to zero when it intercepts the x-axis, in this case, the function is zero for x = -3 and x = -1

[tex]\qquad \textit{perfect square trinomial} \\\\ (a\pm b)^2\implies a^2\pm \stackrel{\stackrel{\text{\small 2}\cdot \sqrt{\textit{\small a}^2}\cdot \sqrt{\textit{\small b}^2}}{\downarrow }}{2ab} + b^2[/tex]

the idea behind the completion of the square is simply using a perfect square trinomial,  hmmm usually we do that by using our very good friend Mr Zero, 0.

if we look at the 2nd step, we have a group as x² - x, hmmm so we need a third element, which will be squared.

keeping in mind that the middle term of the perfect square trinomial is simply the product of the roots of "a" and "b",  so in this case the middle term is "-x", and the 1st term is x², so we can say that

[tex]\stackrel{middle~term}{2(\sqrt{x^2})(\sqrt{b^2})~}~ = ~~\stackrel{middle~term}{-x}\implies 2xb~~ = ~~~~ = ~~-x \\\\\\ b=\cfrac{-x}{2x} \implies b=-\cfrac{1}{2}[/tex]

so that means that our missing third term for a perfect square trinomial is simply 1/2, now we'll go to our good friend Mr Zero, if we add (1/2)², we have to also subtract (1/2)², because all we're really doing is borrowing from Zero, so we'll be including then +(1/2)² and -(1/2)², keeping in mind that 1/4 - 1/4 = 0, so let's do that.

[tex]-3~~ = ~~-2\left[ x^2-x+\left( \cfrac{1}{2} \right)^2 ~~ - ~~\left( \cfrac{1}{2} \right)^2\right]\implies -3=-2\left(x^2-x+\cfrac{1}{4}-\cfrac{1}{4} \right) \\\\\\ -3=-2\left(x^2-x+\cfrac{1}{4} \right)+(-2)-\cfrac{1}{4}\implies -3=-2\left(x^2-x+\cfrac{1}{4} \right)+\cfrac{1}{2} \\\\\\ -3-\cfrac{1}{2}=-2\left(x^2-x+\cfrac{1}{4} \right)\implies -\cfrac{7}{2}=-2\left(x-\cfrac{1}{2} \right)^2\implies \cfrac{7}{4}=\left(x-\cfrac{1}{2} \right)^2[/tex]

[tex]~\dotfill\\\\ \pm\sqrt{\cfrac{7}{4}}=x-\cfrac{1}{2}\implies \cfrac{\pm\sqrt{7}}{2}=x-\cfrac{1}{2}\implies \cfrac{\pm\sqrt{7}}{2}+\cfrac{1}{2}=x \implies \cfrac{\pm\sqrt{7}+1}{2}=x[/tex]

A megaliter is 10,000 times larger than a hectoliter.

The kiloliter is 10^3 times greater than a liter while the hectoliter is 10^4 times greater than the centiliter.

An equation is an expression that shows the relationship between two or more variables.

1 mega liter = 10^6 Liter

1 hectoliter = 10^2 Liter.

Hence, a megaliter is 10,000 (10^6/10^2) times larger than a hectoliter

The kiloliter is 10^3 times greater than a liter while the hectoliter is 10^4 times greater than the centiliter.

The cost of an order of 1 hamburger and 2 orders of fries cost which Nathaniel and Liam bought is $6.5.

A system of equation is the set of equation in which the finite set of equation is present for which the common solution is sought.

Let the cost of 1 hamburger is x dollar and 2 orders of fries is y dollars. Nathaniel bought 3 hamburgers and 2 orders of fries for $12.50. Thus,

[tex]3x+2y=12.5[/tex]

Solve this equation as,

[tex]2y=12.5-3x\\y=\dfrac{12.5-3x}{2}[/tex]                        .....1

Liam bought 2 hamburgers and 4 orders of fries for $13. Thus,

[tex]2x+4y=13[/tex]

Put the value of y in this equation and solve it further,

[tex]2x+4(\dfrac{12.5-3x}{2})=13\\2x+25-6x=13\\-4x=13-25\\-4x=12\\x=\dfrac{12}{4}\\x=3[/tex]

Put this value of x in equation 1,

[tex]y=\dfrac{12.5-3\times3}{2}\\y=\dfrac{3.5}{2}\\y=1.75[/tex]

The cost of an order of 1 hamburger and 2 orders of fries is,

[tex]C=3\times 1+2\times1.75\\C=3+3.5\\C=6.5[/tex]

Thus, the cost of an order of 1 hamburger and 2 orders of fries cost which Nathaniel and Liam bought is $6.5.

Answer: 52 %

Step-by-step explanation: 780/1500 × 1100/1

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

780/1500 x 100 = 52%

The percentage of the amount spent on customs is 52%

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Total budget = $1500

Amount spend on costumes = $780

The percentage of the amount spend on customs.

= 780/1500 x 100

= 52%

Thus,

The percentage of the amount spent on customs is 52%

Given the coordinates in rectangular form, that is, (x, y), where each component belongs to an orthogonal axis of reference. By trigonometry we have six functions to be calculated:

[tex]\sin \theta = \frac{y}{\sqrt{x^{2}+y^{2}}}[/tex]     (1)

[tex]\cos \theta = \frac{x}{\sqrt{x^{2}+y^{2}}}[/tex]     (2)

[tex]\cot \theta = \frac{1}{\tan \theta}[/tex]     (4)

[tex]\sec \theta = \frac{1}{\cos \theta}[/tex]     (5)

[tex]\csc \theta = \frac{1}{\sin \theta}[/tex]     (6)

If we know that x = 20 and y = 48, then the six trigonometric functions are, respectively:

[tex]\sin \theta = \frac{48}{\sqrt{20^{2}+48^{2}}}[/tex]

[tex]\sin \theta = \frac{12}{13}[/tex]
