Answer:

see explanation

Step-by-step explanation:

to determine if the values of y are a solution to the equation, substitute the values of y into the left side and if equal to the right side then they are a solution.

y = 70

[tex]\frac{70}{7}[/tex] - 1 = 10 - 1 = 9 ≠ - 2 → NO

y = 56

[tex]\frac{56}{7}[/tex] - 1 = 8 - 1 = 7 ≠ - 2 → NO

y = - 7

[tex]\frac{-7}{7}[/tex] - 1 = - 1 - 1 = - 2 → YES

y = 0

[tex]\frac{0}{7}[/tex] - 1 = 0 - 1 = - 1 ≠ - 2 → NO

Answer:

Yes. I think that is a pre algebre question.

From the graph of the piecewise function, we have that:

a) The range of the function is (-∞,7).

b) The vertical asymptote is of x = 2, and the horizontal asymptotes are y = -1 and y = -2.

c) The end behavior of the function is described as follows: As x -> -∞, y -> -2 and as x -> ∞, y -> -1.

A piecewise function is a function that has different definitions, depending on the input.

For this problem, the definitions of the function are given as follows:

The graph of the function is given at the end of the answer.

The range of the function is the set that contains all the output values of the function, and in a graph, this is the values of y.

Hence:

The range of the function is (-∞,7).

The asymptotes of the functions are the values of x for which the function is not defined. In this problem, the function is not defined for x = 2, hence the vertical asymptote is of x = 2.

The horizontal asymptotes are the values of the function when it goes to infinity, hence they are y = -2 and y = -1.

The end behavior is given by the limits of the function as it goes to infinity, being closely related to the horizontal asympotes.

Hence:

As x -> -∞, y -> -2 and as x -> ∞, y -> -1.

Please ignore the (60,1) point plotted on the graph, it should be (60,-1).

To find the mean of a set of numbers, we find their sum and divide it by the number of terms there are.

We're given:

The sum of (a + 1) + (a + 4) + (a + 7) + (a + 8) + (a + 10) divided by 5 (because there are 5 numbers) is 12. Write this as an equation:

[tex]12=\dfrac{(a + 1) + (a + 4) + (a + 7) + (a + 8) + (a + 10)}{5}[/tex]

Simplify:

[tex]12=\dfrac{a + 1 + a + 4 + a + 7 + a + 8 + a + 10}{5}\\\\12=\dfrac{5a + 30}{5}\\\\12=a +6\\a=6[/tex]

The billboard is not tall enough as the height is 27.5ft which is  less than 30ft.

The comparison of two quantities having the same units is called as Ratio.

ratio between quantity a and b is  represented by a:b .

In the given question

The bill board should have at least 30ft height.

Height of lady = 5 ft 6 inches

                        =5.5 ft     ...( as 6inch=0.5ft )

If the height of the lady is 5.5ft shadow length = 7 feet

Since the units of height of lady and length of shadow is same .

hence ratio can be used ,

also given that length of billboard = 35 ft.

Let the height of the bill board = x ft

The above situation can be represented using ratio as

(height of lady) / (length of shadow of lady)=(height of billboard)/( length of billboard shadow)

Substituting the values we get

5.5/7=x/35

On solving further we get

(5.5/7)*35=x

5.5*5=x

x=27.5

The height of the billboard is 27.5 ft  .

Since , it is given that the height of the bill board should be at least 30ft tall , and the height of the billboard is 27.5ft.

Therefore , the billboard is not tall enough as the height is less than 30ft.

LCM of 8, 16 and 24

Decompose to prime factors
8/2 = 4; 4/2 = 2. So 8 = 2 x 2 x 2

16 =  8 x 2  = (2 x 2 x 2) x 2

24 =  8 x 3 = (2 x 2 x 2) x 3

2 x 2 x 2 is common, 2 appears once more as a factor in 16 and 3 appears in 24 so the LCM = (2 x 2 x 2) x 2 x 3 = 48

A relation that does not have the function property of each and every input having exactly one output.

A function is defined as a relation between  a group  of inputs having one output each. In simple words, a function may be a  relationship between inputs where each input is related to exactly one output. Every function  features a  domain and range. A function is usually  denoted by f(x) where x is the input.

The types of functions can be broadly classified into four types.  supported  Element: One to one Function, many  to at least one  function, onto function, one  to at least one  and onto function, into function.

A function  may be a  relation between a set of inputs (called the domain) and a permissible set of outputs (called the codomain),  such  each input is related to exactly one output.

Answer: -119 feet relative to the surface of the water.

Step-by-step explanation:

Shark Depth ( x ) + Distance from Shark and Diver ( 38 ) = Divers position (-157)
x = -119

The diver is at -157 feet relative to the surface. The shark is swimming 38 feet above the diver, making its position -119 feet relative to the surface.

Given that,

Diver's depth: -157 feet (relative to the surface of the water)

Shark's position: 38 feet above the diver

The question asks for the position of the shark relative to the surface of the water.

The position of the shark can be determined by adding the distance above the diver to the depth of the diver.

So, the position of the shark would be:

-157 feet (diver's depth) + 38 feet (distance above the diver) = -119 feet relative to the surface of the water.

Hence,

The shark is located at -119 feet relative to the surface of the water.

System of equations modeling the given conditions:

x + y = 94

x - y = 36

Solving:

In order to use substitution, you have to isolate one of the variables in either of the equations

Using the second equation and isolating the variable x:

x - y = 36

x = 36 + y

then you can substitute x back into the first equation

36 + y + y = 94

36 + 2y = 94

2y = 58

y = 29

and then substitute 29 for y into either one of the equations

x + 29 = 94

There were 733 general tickets sold and 255 reserved tickets.

Let the general admission = g

Let the reserved seats = r

Therefore, the appropriate equation will be:

g + r = 988

4g + 6.5r = 4589.50

From equation i r = 988 - g

4g + 6.5r = 4589.50

4g + 6.5(988 - g) = 4589.50

4g + 6422 - 6.5g = 4589.50

6.5g - 4g = 6422 - 4589.50

2.5g = 1832.50

g = 1832.50/2.5

g = 733

Since g + r = 988

r = 988 - 733

r = 255

Therefore, there were 733 general tickets sold and 255 reserved tickets.

The equivalent number of socks to 2.3 shoes is 14.95 socks

Fractions are expression written as a ratio of two integers. For instance If 1 shoe equals 6.5 socks, this can be written as:

1 shoe = 6.5 socks

In order to determine the number of socks for 2.3 shoes, we will have:

2.3 shoes = x socks

Determine the ratio

1/2.3 = 6.5/x

Cross multiply

1 * x = 2.3 * 6.5

x =  2.3 * 6.5

x = 14.95

1.  'x' = -18/4

2. 'x' = -4/3

The equations are Not Equivalent.

An equation between two variables that gives a straight line when plotted on a graph. Or we can say,

A linear equation is defined as an equation that is written in the form of Ax+By=C. It is the combination of two variables and a constant value present in them.  

We have given

(x/3) - 2 = (5x/3) + 3

(5x/3) - (x/3) = -2 - 3

4x/3 = -6

  4x = -6 × 3

    x = -18/4

In first equation we got the value of x is -18/4.

Two systems of linear equations are equivalent if and only if they have the same set of solutions.  

To determine the equivalent of linear equation,

First, we need to find the value of "x" for each equation. If "x" is the same for both equations, then they are equivalent. If "x" is different then the equations are not equivalent.

We have equation

x(x + 1) = (x + 2)²

x² + x = x² + 4 + 4x        

(We have solved  (x + 2)² by using algebraic identity (a + b)² = a² + b² + 2ab.)

  4x - x = x²- x² - 4

       3x = -4  

         x = -4/3

In the second equation we got the value of x is -4/3.

Hence, as we can see it clearly that the value of x is not same in both equations so this is Not Equivalent.

Differentiate the above function to determine the average rate of change

So, we have

f'(x) = 3x^2 - 9

Set the function to greater than 0

So, we have
