Which is true when a negative number is subtracted from a positive number?

2 answers:

4 0

Subtracting a number is the same as adding its opposite. So, subtracting a positive number is like adding a negative; you move to the left on the number line. Subtracting a negative number is like adding a positive; you move to the right on the number line.
So it’s d

Answer:

D is the correct answer

Step-by-step explanation:

it honestly depends on what the numbers are

for example, 12 -6, you would get 6.

but if the question is something like 4 -8, you'd have -4

Find f(x) and g(x) such that h(x)equals(fcircleg)(x). h left parenthesis x right parenthesis equals left parenthesis 2 x pl

GaryK [48]

Answer:

f(x) = x^3
g(x) = (2x+4)^2

Step-by-step explanation:

There are many ways to decompose h(x) into f(x) and g(x). The main purpose of the exercise seems to be to get you to think about the operations that are performed on x, then divide that list of operations into two parts.

In the function ...

h(x) = (2x +4)^6

the variable x is ...

multiplied by 2
4 is added to the sum
the sum is raised to the 6th power

Of course, the 6th power can be considered as the cube of a square or the square of a cube, if you like.

In the decomposition shown in the answer above, we have chosen to put most of this list in g(x), including the square of the sum. Then we have made f(x) be the cube of that square.

h(x) = f(g(x)) = (2x+4)^6

When f(x) = x^3, this is ...

h(x) = f(g(x)) = g(x)^3 = ((2x+4)^2)^3

so ...

g(x) = (2x+4)^2 . . . and . . . f(x) = x^3

_____

Other possible decompositions are ...

g(x) = 2x
f(x) = (x+4)^6

g(x) = (x+2)
f(x) = (2x)^6

g(x) = 2x+4
f(x) = x^6

or ... (many others)

A class survey found that 29 students watched television on Monday, 24 on Tuesday, and 25 on Wednesday. Of those who watched TV

gizmo_the_mogwai [7]

Answer:

There were 49 students in the class

Step-by-step explanation:

To solve this problem, we must build the Venn's Diagram of this set.

I am going to say that:

-The set A represents the students that watched TV on Monday

-The set B represents the student that watched TV on Tuesday.

-The set C represents the students that watched TV on Wednesday.

We have that:

$A = a + (A \cap B) + (A \cap C) + (A \cap B \cap C)$

In which a is the number of students that only watched TV on Monday, $A \cap B$ is the number of adults that watched TV both on Monday and Tuesday, $A \cap C$ is the number of students that watched TV both on Monday and Wednesday, and $A \cap B \cap C$ is the number of students that watched TV on every day.
