Which step is the most efficient way to find the solution of x + 4 > -8? Answer choices: A: Add 4 to both sides. B: Subtract 4 from both sides and switch the inequality symbol. C: Substitute 1 for x and see if it works. D: Subtract 4 from both sides.

Answers

Answer 1

Answer:

d

Step-by-step explanation:

Answer 2

The most efficient step to finding the solution to the given inequality is, to subtract 4 from both sides. Option D is correct.

Given that,
To determine which step is the most efficient way to find the solution of x + 4 > -8.

What is inequality?

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

here,
Given inequality,
x + 4 > -8
Subtract 4 from both sides,
x + 4 - 4 > - 8 - 4
x > -12

Thus, the most efficient step to finding the solution to the given inequality is, to subtract 4 from both sides. Option D is correct.

Reduce to the simplest form. -9/6 + (-3/5)

Answers

Answer:

[tex]-\frac{21}{10}[/tex] or [tex]-2.1[/tex] (they're the same)

Step-by-step explanation:

Simplify: [tex]-\frac{9}{6} + (-\frac{3}{5}) = -\frac{9}{6} - \frac{3}{5}[/tex]  Find a common denominator. The LCM of 6 and 5 is 30, so multiply the numerator and the denominator by the same thing: 6 × 5 = 30, -9 × 5 = -45, 5 × 6 = 30, 3 × 6 = 18Write the new fractions: [tex]-\frac{45}{30} - \frac{18}{30}[/tex]  Subtract: -45/30 - 18/30 = [tex]-\frac{63}{30} = -\frac{21}{10}[/tex]

An airline records data on several variables for each of its flights, model of plane, amount of fuel used, time in flight,
number of passengers, and whether the flight arrived on time. The number and type of variables recorded are
1 categorical, 4 quantitative (1 discrete, 3 continuous)
O 3 categorical, 2 quantitative (1 discrete, 1 continuous)
O 1 categorical, 4 quantitative (2 discrete, 2 continuous)
2 categorical, 3 quantitative (1 discrete, 2 continuous)
O 2 categorical, 3 quantitative (2 discrete, 1 continuous)

Answers

Answer:

The correct option is;

2 categorical, 3 quantitative (1 discrete, 2 continuous)

Step-by-step explanation:

A categorical variable which is otherwise known as a nominal variable is one which can be qualified as belonging to one class or category of objects or the other, depending on its attributes, and not based on order of the classes.

Therefore;

1) The model of the plane, and 2) whether the flight arrived on time, are categorical variable

A quantitative variable is a variable that indicates measurement and therefore, indicates the numerical magnitude of a measurement.

Therefore;

1) Amount of fuel used, 2) Time in flight, 3) The number of passengers are quantitative variables

Quantitative variables can be either discrete or continuous

A discrete quantitative variable is one that has a finite number of possible values or which may have an infinite but countable number of values

Therefore;

1) The number of passengers which is countable and exact is a discrete quantitative variable

A continuous variable is one whose exact or accurate value range is infinite or a variable with a limitless value set such as the range of values between two real numbers

Therefore;

1) Amount of fuel used and 2) Time of flight are continuous quantitative variables.

Sorry I also need help with this question

Answers

Answer: B

Step-by-step explanation:

(f/g) means to divide f(x) by g(x).

[tex](f/g)(x)=\frac{3x+2}{3x-5}[/tex]

To find the domain, you set the domain equal to zero and solve for x.

3x-5=0                   [add both sides by 5]

3x=5                       [divide both sides by 3]

x=5/3

Now, we know that B is the correct answer.

It cost Hudson $28.20 to send 188 text messages. How much would it cost to send 63 text messages? Good luck!

Answers

Answer:

$9.45

Step-by-step explanation:

1.  First, you want to figure out how much one text message costs.  To do this, divide the dollar amount (28.20) by the number of text messages (188).  You get 0.15, or $0.15 per text message.

2. Using this $0.15 per text message, you can calculate how much 63 text messages costs.  You simply multiply $0.15 by 63 to get $9.45, which is your answer.

The graph of y = f(x) is shown below. What are all of the real solutions of f(x)
= 0?

Answers

Answer:

x = -8, 0 and 6

Step-by-step explanation:

Graphed function in the picture,

y = f(x)

Solutions of a function are defined by the points on x-axis where the graph intersects or touches.

In the given graph, curve of the function touches the x-axis at x = -8 and crosses the x-axis at x = 0, 6

Therefore, real solutions of the function 'f' will be x = -8, 0 and 6.

547 and 14 and 7658 - 7000 = 658 - blank = 98 -98 = 0 what is the answer

Answers

Solution :

7658 - 7000 = 658 - blank

658 = 658

So here, blank is 0.

547 - 7000 = 658 - blank

-7111 = 658 - blank

Blank = 7769

14 - 7000 = 658 - blank

- 6986 = 658 - blank

Blank = 7644

-8(7x+8)=-8x+34 i need help solving this equation .

Answers

Answer:

x = -49/24

Step-by-step explanation:

The first step in solving this equation is to use the distributive property to eliminate the parentheses on the left side of the equation.

-8(7x+8) = -8x + 34

-56x - 64 = -8x + 34

Next, we should add 8x to both sides of the equation.

-48x - 64 = 34

Next, we can add 64 to both sides of the equation.

-48x = 98

Finally, we can divide both sides of the equation by -48 to get the variable x alone on the left side of the equation.

x = -98/48 = -49/24

Therefore, the correct answer is -49/24.
