Which of the following could be a value of x in the following inequality?
-5(x - 2) > 4+4(x + 6)

Answer:

D

Step-by-step explanation:

To evaluate f(- 2) substitute x = - 2 into f(x), that is

f(- 2) = (- 2)² - (- 2)³ = 4 - (- 8) = 4 + 8 = 12 → D

Answer:

The answer is 54

Step-by-step explanation:

Let us evaluate the exponent first

(3/4)^3 = 27/64

so we have

27/64 divided by 1/128

= 27/64 * 128/1 = 27 * 128/64

= 27 * 2 = 54

Answer:

[tex]the \: slope \: is \to \boxed{60}[/tex]

Step-by-step explanation:

[tex]if \to C=65+60t \\ C=60t + 65 \\ but \: the \: \boxed{ c - intercept} \: is \: in \: the \: form \to \\ c = mt + b \\ hence \to \\ 60t = mt \\ m = \frac{60t}{t} \\ m = 60 \\ the \: slope \: is \to \boxed{60}[/tex]

We want to analyze the given linear equation, we will find that the slope is 60, and it means that he charges 60 per hour.

A general linear equation is written as:

y = a*x +b

Where a is the slope and b is the y-intercept.

In this case, we have the equation:

c(t) = 60*t + 65

Is easy to identify that the slope is equal to 60.

Given that we know that he charges per hour, and that t represents the number of hours that the electrician worked, we can assume that the slope represents how much the electrician charges per hour.

Answer:

x = - 2, x = 9

Step-by-step explanation:

Given

f(x) = [tex]\frac{x^2-9x}{x^2-7x-18}[/tex]

The denominator of f(x) cannot be zero as this would make f(x) undefined.

Equating the denominator to zero and solving gives the values that x cannot be.

x² - 7x - 18 = 0

(x - 9)(x + 2) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 9 = 0 ⇒ x = 9

The excluded values are x = - 2, x = 9

Answer:

Step-by-step explanation:

Answer:

On Tuesday

591 burgers are sold.

Some are hamburgers and some are cheeseburgers.

59 fewer cheeseburgers sold than hamburgers.

Number of cheeseburgers --> x

Number of hamburgers --> y

x+y= 591 --> x = 591-y

x = y-59

so

591-y = y-59

-2y = -650

y = 325

so

x = 325-59

x =266

The hamburger shop sold a combined total of 591 hamburgers and cheeseburgers on Tuesday.

Let's represent the number of hamburgers sold as "H" and the number of cheeseburgers sold as "C." From the information given, we have two equations:

1. H + C = 591 (The combined total of hamburgers and cheeseburgers sold on Tuesday was 591).

2. C = H - 59 (There were 59 fewer cheeseburgers sold than hamburgers).

Now, we can use substitution to solve for the number of hamburgers: Substitute the value of C from the second equation into the first equation:

H + (H - 59) = 591

Now, combine like terms:

2H - 59 = 591

Next, isolate the term with H:

2H = 591 + 59

2H = 650

Now, solve for H:

H = 650 / 2

H = 325

So, they sold 325 hamburgers on Tuesday. To find the number of cheeseburgers sold, use the second equation:

C = H - 59

C = 325 - 59

C = 266

They sold 266 cheeseburgers on Tuesday. To find the total sales, add the number of hamburgers and cheeseburgers: Total sales = 325 (hamburgers) + 266 (cheeseburgers) = 591.

Answer: 13

Step-by-step explanation:

3X + 3 - 3 = 42 - 3

3X = 39

3X/3 = 39/3

X = 13

Which means that the first number is 13, the second number is 13 + 1 and the third number is 13 + 2. Therefore, three consecutive integers that add up to 42 are 13, 14, and 15.

13 + 14 + 15 = 42

We know our answer is correct because 13 + 14 + 15 equals 42 as displayed above.

Answer:

You have 50 lb of sand, and you are pouring this into a wagon.

We have the relationship:

y = 10lb*x

Where x is the number of bags of sand that you poured into the wagon.

We know that in total, you have 50 lb of sand, then let's find the domain of this function (Domain is the set of the possible values of x)

The minimum will be when x = 0, you poured 0 bags at this point.

And the maximium will be when y = 50lb

y = 50lb = 10lb*x

     50lb/10lb = x = 5

Then the domain is 0 ≤ x ≤ 5

Then we only will graph this in that range of values.

The graph will be something like:

The person who entered the room is 3 years old.

Answer:

3 years old

Step-by-step explanation:

x= age of the person who entered the room

The sum of 21,+ 24,+ 18,+ 15,+ 15 = 93

(93+x )     divided into 6 = 16

Multiply both sides by 6

93+x = 96

x=3

 93+3= 96

96/6 = 16
