Find (f+g)(x) and (f-g)(x)
f(x)=2x+7 g(x)=5x-4

Answers

Answer 1

Answer:

for (f+g)(x): 7x + 3; x = -3/7

for (f-g)(x): -3x - 3; x = -1

Step-by-step explanation:

(f+g)(x) = (2x+7)+(5x-4)

Eliminate parentheses.

2x + 7 + 5x -4

Combine like terms.

7x + 3

If you are solving for x, move the 3 to the other side.

7x = -3.

Then divide each side by 7.

x = -3/7

(f-g)(x) = (2x+7) - (5x -4)

Distribute the negative.

(2x+7) + (-5x+4)

Eliminate parentheses.

2x + 7 - 5x - 4

Combine like terms.

-3x -3

If you are solving for x, move the -3 to the other side.

-3x = 3

Then divide each side by -3.

x = -1.

Order the numbers from least to greatest. Put the lowest number on the left. 11/12 , 9/8 , 1/3 ,

Answers

Answer:

1/3,11/12,9/8

Step-by-step explanation:

Hi! Let's start off with creating common denominators for all three of these fractions.

The LCM (least common multiple) of these three denominators is 24, which means that the three numbers you see at the bottom of the fraction (12, 8, and 3) all in some way have a number that will cause it to multiply to 24, and will make it much more easier to determine the fraction.

1) Change all of the denominators into 24 by multiplying the right number

11/12×2/2=>22/24

9/8×3/3=>27/24

1/3×8/8=>8/24

So now I want you to imagine that the denominators don't exist. From there, you can sort out the fractions from least to greatest! Hope you understood this :)

Describe the triple constraint. What are the three components and what is the relationship between them

Answers

Answer:

The triple constraint represents the three constraints or inputs which control the project's capacity to produce.

The three components are Budget, time, and scope.

The relationship between them is an interdependent or triangular shape.

Step-by-step explanation:

The triple constraint represents the three constraints or inputs which control the project's capacity to produce. Budget, Scope and Time.

Budget - The budget describes the estimated cost of the project. Time: The time represents the deadline to complete the project.Scope: This is simply what needs to be provided.

These 3 components are dependent to each other.

For example, if time is restricted then scope and budget will be affected. similarly.

The relationship between the three is that one of the two other components must decrease while one component increases for the project to succeed as expected.

jester has a piece of wood measuring 1 and 2/3 m.he needs to cut in pieces measuring 3/4 m. long.how many pieces of wood did jester cut.​

Answers

Answer:

He can cut 2 pieces.

Step-by-step explanation:

Given that,

Jester has a piece of wood measuring 1 and 2/3 m = 5/3 m

He needs to cut in pieces measuring 3/4 m

We need to find the number of pieces in which he cut the wood. Let there are x no. of pieces.

[tex]x=\dfrac{\dfrac{5}{3}}{\dfrac{3}{4}}\\\\=\dfrac{5}{3}\times \dfrac{4}{3}\\\\=2.23\[/tex]

or

x = 2

So, he will cut it into approx 2 pieces.

What are arithmetical operations?

The four fundamental operations of arithmetic are addition, subtract, multiply, and division of two or more numbers. Included in them is the study of integers, especially the order of operations, which is important for all other aspects of mathematics, notably algebra, information management, and geometry.

From the data in the question,

15-foot statue = 20-foot shadow

x-foot man's height = 4-foot long shadow

20x = 60

x = 60/20

x = 3 foot.
