The solution of the given expression is 63.

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Here the given expression is :

3(a-2b)

where, a = -3

and, b = -12

Now, substitute the value of a and b in the given expression :

3(a-2b)

= 3(-3-2x -12)

= 3(-3 + 24)

= 3(21)

= 63

Therefore, the solution of the given expression is 63.

Group of answer choices

1 over 2

1 over 3

1 over 4

1 over 5

Answers

Answer:

1/4

Step-by-step explanation:

The sides go from 4 units to 1 unit so the dilation must be 1/4

Answer:

1 over 4

Step-by-step explanation:

Step 1. The shape dilates smaller than itself so will always be less than 1

Step 2. We count P to 0 in the larger shape and see = 4 unit

and compare to P' to 0' in the smaller shape and see = 1 unit

Answer. The dilation is 1/4

A company charges $3.00 for every 2 pounds of oranges sold plus a $3.00 shipping fee. Based on this information, which graph best shows this relationship between the cost of oranges, y, and the number of pounds, x?

Answers

b is the answer because of 3 dollars every 2 pounds

The obtained coordinate points to plot the graph are matching with graph A. Therefore, option A is the correct answer.

Given that, a company charges $3.00 for every 2 pounds of oranges sold plus a $3.00 shipping fee.

What is graph?

In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related".

Let the total cost of oranges be y and the number of pounds of oranges be x.

So, the equation to represent the given situation is y=2x+3

By substituting x = 1, 2, 3, 4, 5,....we get

y = 2(1)+3=5

y = 2(2)+3 = 7

y = 2(3)+3 = 9

y = 2(4)+3 = 11

So, the coordinates to plot the graph are (1, 5), (2, 7), (3, 9) and (4, 11) and so on.

The obtained coordinate points to plot the graph are matching with graph A. Therefore, option A is the correct answer.

need help on slope pt 2. explain it pls

Answers

Answer:

Slope = -3/2 y-intercept = (0,1)

Step-by-step explanation:

The slope is rise/run.

We can take the points (-2,4) and (0,1) to find the slope.

In the same amount of time x increases by 2, y decreases by 3. This gives us the slope of -3/2.

The y-intercept is the y level that the slope passes through when x = 0

On this line, that is the point (0,1)

Reminder that points are (x,y)

Slope=-3/2; y-intercept (0,1)

The line crosses the y axis at the point one making that they answer for the y-intercept.

The slope is -3/2 because it went down 3, making it negative, and over two.

Do the stuff in the parenthesis first (PEMDAS)

9 + 1.34 + 1/2 (5.24)

Then do the multiplication

9 + 1.34 + 2.62

Then add all the numbers together

10.34 + 2.62

Answers

Answer:

-6.809 > -6.812|

-6.809| < -6.812|

Step-by-step explanation:

Answer:

-6.809 > -6.812 and |-6.809| < |-6.812|

Step-by-step explanation:

-6.809 is greater than -6.812 because the number is more closer to zero.

A negative number more closer to zero is greater than a negative number that is farther away from zero.

Also, |6.809| <| -6.812| Because the absolute value for both numbers is 6.809 and 6.812 meaning the number 6.812 is greater than the number 6.809.
