Answer:

23y-8

Step-by-step explanation:

First add together all of the terms that are next to a variable:

2y+10y+5y+6y=23y

Then add together all of the integers that are alone:

-9+10+(-7)+(-2)= -8

Add the two terms together and you get:

23y-8

b. no

Answer:

2.The values for the independent variable

3.The set of all values for input of a function

5.The set of all x values

Step-by-step explanation:

Answer:

f(x) = 5x – 1

to find the inverse equate f(x) to y

That will be

f(x) = y

>>>>

Interchange the terms >>>

x = 5y - 1

then make y the subject

then we have

5y = x + 1

then if you divide both sides by 5

y = x+1/5

therefore f^-1(x)= x + 1/5

hope this helps you

Answer:

12. -11

13. 2

Step-by-step explanation:

12. First recall the order of operations (BEDMAS): Brackets, Exponents, Division, Multiplication, Addition, Subtraction

For question 12 there is a division and its priority is before other operations in the equation so you must divide 16/-2 first which gives you -8.

From there because addition and subtraction is on the same level of order, you would do the question straight as it is shown (but replace 16/-2 with -8.

Your new equation is -10-8+7 = -11

13. follow the same as above using BEDMAS. It may help to look at it with additional brackets: ((-68)/(-4)) + ((5 x (-3))

Division and multiplication is on the same level in BEDMAS so first divide -68/-4 = 17

Second multiply 5 x -3 = -15

Now you can combine the two answers using addition: 17 + (-15) = 2

    Function defining the cost of buying and shipping will be represented by,

C(x) = ax + b

Here, a = price of one jar, b = shipping charges and x is the price of jar preserve

     Function representing the cost C for buying and shipping 'x' jars of preserves will be,

C = $(9.15x + 3.75)

  It's given in the question,

Let the number of jars purchased = x

Therefore, charges for 'x' jars = $8.50x

So the shipping and handling charges for shipping 'x' jars = $(3.75 + 0.65x)

Therefore, total charges for shipping and preserving 'x' jars = $(3.75 + 0.65x) + $8.50x

        Therefore, function representing the cost C for buying and shipping 'x' jars of preserves will be,

C = $(3.75 + 0.65x) + $8.50x

C = $(9.15x + 3.75)

Answer:

The number is 20

Step-by-step explanation:

Let the number be x

5(x - 9) = 2x + 15

5x - 45 = 2x + 15

5x - 2x = 15 + 45

3x = 60

x = 60/3

x = 20

Answer:

The number is 20

Step-by-step explanation:

Five times the difference of a number and 9

5(x-9)

is equal to twice the number plus 15.

=2x+15

5(x-9)=2x+15

Distribute

5x-45 = 2x+15

Subtract 2x from each side

5x-45-2x = 2x+15-2x

3x-45 = 15

Add 45 to each side

3x-45+45 =15+45

3x = 60

Divide by 3

3x/3 = 60/3

x =20

The graph fourth represents the graph of the function y = ∛(2x) option (C) is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The equation for the graph is:

y = ∛(2x)

The above function is curve function.

Plug x = 0

y = 0

x = 1

y = 2

x = 4

y = 2

And so on

A function with a variable beneath the cube root is known as a cube root function. The functions' most fundamental variations are (x) and 3(x), correspondingly. By locating a few sites that satisfy any function, plotting them, and then interrelating them, we may graph these fundamental functions.

Thus, the graph fourth represents the graph of the function y = ∛(2x) option (C) is correct.

We are given the equation:

[tex]\lim_{x \to 1} \frac{f(x)-8}{x-1} = 10[/tex]

which can be rewritten as:

[tex]\frac{\lim_{x \to 1}[f(x)-8]}{\lim_{x \to 1}[x-1]} = 10[/tex]

[tex]\lim_{x \to 1}[f(x)-8] = 10*\lim_{x \to 1}[x-1][/tex]

[tex]\lim_{x \to 1}[f(x)-8] = \lim_{x \to 1}[10x-10][/tex]

which means that..

[tex]f(x) - 8 = 10x - 10[/tex]

[tex]f(x) = 10x - 10 + 8[/tex]

[tex]f(x) = 10x - 2[/tex]

Finding the limit:

[tex]\lim_{x \to 1} f(x) = \lim_{x \to 1} (10x - 2)[/tex]

[tex]\lim_{x \to 1} f(x) = 10(1) - 2[/tex]

[tex]\lim_{x \to 1} f(x) = 8[/tex]

Answer:

8.

Step-by-step explanation:

lim x --> 1 of  10x - 10 / (x - 1)

= lim x -->1  of 10/1  ( Because when x = 1 the function = 0/0 so we can apply

L'hopitals rule  which states that that if f(x)/ g(x) = 0/0 when x = limit value, then the limit is = f'(x) / g'(x))

So f(x) - 8 = 10x - 10

f(x) = 10x - 10 + 8

f(x) = 10x - 2

- and the limit as x ---> 1 of this is

10(1) - 2

= 8.
