what is the difference between 4x and x4? evaluate both of these expressions when x = 2

Answers

Answer:

There is no difference. 4x and x4 are both meaning 4 times x and x times 4

Step-by-step explanation:

If x = 2, then 4 x 2 = 8.

x4 is the same thing

2 x 4 =  8

Note:

When the numbers are there together, without an operation, it means multiplication.

The value of the expression 4x is 8.

The value of the expression [tex]x^4[/tex] is 16.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

4x and [tex]x^4[/tex]

For x = 2,

4x = 4 x 2 = 8

[tex]x^4[/tex] = [tex]2^4[/tex] = 2 x 2 x 2 x 2 = 16

Thus,

The values of the expression are 8 and 16.

How do you solve 2(x-6)=x-14

Answers

2(x-6)=x-14
2x-12=x-14
2x -x=-14+12
x= -14+12
x=-2

Answer:

x = -2

Step-by-step explanation:

[2(x-6) = x - 14]

Multiply 2 by x and (-6) in parenthesis, distribution

[2x -12 = x - 14]

Add 12 to both sides

[2x = x - 2]

Subtract x from both sides

[x = -2]

In school ,there are 3 girls for every 2 boys . There are 650 students in total . How many students are girls ?

Answers

Answer:

Girls = 390

Step-by-step explanation:

Set up a proportion:

In a sample of 3:2, you have 5 kids in all.

So the the ratio of girls to kids in a sample of 5 is 2:5.

So set up a proportion:

(3/5) = (x/650)

5x = 650(3)

5x = 1950

x = 390

Answer:

390

Step-by-step explanation:

Let number of boys be b and girls be g. Then we have:

g/b = 3/2g + b = 650

From the first equation b is:

b = 2g/3

Substitute b in the second equation

g + 2g/3 = 6505g/3 = 650g = 650*3/5g =  390

sold 636 tickets and took in $4974 in revenue. How many tickets were sold to senior citizens?

Answers

Answer:

250

Step-by-step explanation:

x is adult tix, y is senior tix

9x + 6y = $4974

x+y= 636

x=636-y

9(636-y) +6y = 4974

5724 - 9y + 6y = 4974

-3y = 4974-5724

-3y=-750

What is an equation of the line that passes through the point (5, 4) and is parallel to

Answers

Answer:

6x - 5y does not change as it is parallel so I put x = 5 & y = 4 in this equation and the result is 6 × 5 - 5 × 4 = 30 - 20 = 10 so the parallel equation is 6x - 5y = 10

an exponential function is graphed on the grid

based on the graph, which statement about the function is true

a) the domain is the set of all real numbers

b) the domain is the set of all real numbers less than 3

c) the range is the set of all real numbers greater than or equal to 0

d) the range is the set of all real numbers greater than or equal to -9

Answers

Answer:

a) the domain is the set of all real numbers

Step-by-step explanation:

Given:

An exponential function and its graph.

A line parallel to [tex]x[/tex] axis is drawn at [tex]y=-9[/tex] which is a dashed line.

Dashed line means, the function does not attain a value equal to [tex]y=-9[/tex].

Domain of a function, [tex]y=f(x)[/tex] is the set of values which can be possible for the variable [tex]x[/tex] that can be given as input.

Range of a function, [tex]y=f(x)[/tex] is the set of possible values of [tex]y[/tex] i.e. the output of the function.

As seen from the graph, the domain of the exponential function does not have any constraint on it.

Therefore, any real number can be given as input.

So, a) The domain is the set of all real numbers.

Let us discuss about the range of function.

As stated above as well, the range of the function can not contain the value [tex]y=-9[/tex].

And there is no value possible below it.

So, the range is all real numbers greater than -9.

The answer is:

"a) the domain is the set of all real numbers"  is true.
