What is the value of x in the equation 3 - 2x= -1 5x?​

Answer:

VOLUME

Step-by-step explanation:

It is not surface area. I put that and it was WRONG!!!

The minimum amount of paper needed to cover a cylinder is its surface area.

The surface area of a cylinder can be defined as the amount of space covered by the flat surface of the bases of the cylinder and the curved surface of the cylinder.

Here, we need to cover cylinder by paper

So, paper cover its whole surface area.

Thus, the minimum amount of paper needed to cover a cylinder is its surface area.

Answer:

x^2 +14x+49

Step-by-step explanation:

The standard form of the polynomial (x+7)² is x² +14x+49.

A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The polynomial will be represented as,

E =  (x+7)²

E = x² +14x+49.

Answer: f(x)= -2x+1

Step-by-step explanation:

The expression for f(x), when we rewrite [tex]\frac{64^x}{4^{5x-1}}[/tex] as [tex]4^{f(x)}[/tex] will be [tex]4^{-2x+1}[/tex].

Expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

We have,

[tex]\frac{64^x}{4^{5x-1}}[/tex]

So,

Now, to rewrite in form of [tex]4^{f(x)}[/tex],

So,

Rewrite the given expression in the form of 4,

i.e.

[tex]\frac{64^x}{4^{5x-1}}[/tex]

[tex]=\frac{(4^3)^x}{4^{5x-1}}[/tex]

[tex]=\frac{(4^3x)}{4^{5x-1}}[/tex]

NOw,

Using Exponent rule,

We get,

[tex]=4^{3x-(5x-1)}=4^{3x-5x+1}[/tex]

On solving we get,

[tex]=4^{-2x+1}[/tex]

So,

[tex]4^{f(x)}=4^{-2x+1}[/tex]

Hence, we can say that the expression for f(x), when we rewrite [tex]\frac{64^x}{4^{5x-1}}[/tex] as [tex]4^{f(x)}[/tex] will be [tex]4^{-2x+1}[/tex].

Step-by-step explanation:

Given that :

Cost of speaker = $22

Cost per song = $1.25

Sales tax rate = 7.5%

Expression to obtain the amount of sales tax on entire purchase : 0.075(22 + 1.25s)

Expanding the expression :

0.075(22 + 1.25s)

(0.075 * 22) + (0.075 * 1.25s)

1.65 + 0.09375s

Rounding to the nearest hundredth :

Sales tax on entire purchase :

1.65 + 0.09s

Answer:

$10

Step-by-step explanation:

Let the number of 30 day periods be x.

[tex]90-2x=70-1.5x \\ \\ 20=0.5x \\ \\ x=40[/tex]

When x=40, the value is 90-2(40)=$10.

The value of each card will be $ 10 after 40 periods, where the value of the first and second cards are equal.

Given data:

Let x represent the number of 30-day periods that have passed since the gift cards were obtained.

For the first gift card with $90 initial value and losing $2 for each 30-day period:

Value of the first card = Initial value - Loss per period * Number of periods

Value of the first card = $90 - $2 * x

For the second gift card with $70 initial value and losing $1.50 for each 30-day period:

Value of the second card = Initial value - Loss per period * Number of periods

Value of the second card = $70 - $1.50 * x

Now, to find when the two cards have equal value x:

Value of the first card = Value of the second card

$90 - $2 * x = $70 - $1.50 * x

On simplifying the equation:

$90 - $70 = $2 * x - $1.50 * x

$20 = $0.50 * x

x = $20 / $0.50

x = 40

After 40 periods of 30 days each, the two cards will have equal value.

Now, determine the value of each card at this point:

Value of the first card = $90 - $2 * 40 = $90 - $80 = $10

Value of the second card = $70 - $1.50 * 40 = $70 - $60 = $10

Hence, both cards will have a value of $10 when they have equal value after 40 periods.

Answer:

Step-by-step explanation:

You have to figure out what has to multiply by itself to get to that number.

So for example, 121. The square root is more than 10 because 10 times 10 equals 100. It's less than 15 because 15 times 15 is a little over 200. If you have your multiplication tables memorized, you'd know that 11 multiplied by itself is 121. Therefore, the square root to 121 is 11. Hope this helps! (:

The value of the expression of the composite function f(g(x)) = 4x^2 - 3

Expressions are mathematical statements that are represented by variables, coefficients and operators

The given parameters are:

f(x) = 4x + 1

g(x) = x^2 - 1

The composite function is given as

f(g(x)

The above composite function is calculated as

f(x) = 4x + 1

Substitute x for g(x) in the above function

So, the above function becomes

f(g(x)) = 4g(x) + 1

Substitute x^2 - 1 for g(x) in the above function

So, the above function becomes

f(g(x)) = 4(x^2 - 1) + 1

Evaluate the products in the above equation

So, we have

f(g(x)) = 4x^2 - 4 + 1

Evaluate the sum in the above equation

So, we have

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

Hence, the value of the composite function f(g(x)) = 4x^2 - 3

Question 1-- $250+$2(100)= 350 dollars

Question 2-- $250+$2(150)= 400 dollars

Step-by-step explanation:

To calculate the band's total pay for x number of tickets sold, we can use the following expression Total pay [tex]= $250 + ($2 * x)[/tex] For example, if the band sells 100 tickets, the calculation would be: Total pay [tex]= $250 + ($2 * 100) = $250 + $200 = $450[/tex]

Therefore, the band would make $450 for selling 100 tickets. Similarly, if the band sells 150 tickets, the calculation would be: Total pay [tex]= $250 + ($2 * 150) = $250 + $300 = $550[/tex]

Hence, the band would make $[tex]550[/tex]for selling 150 tickets. This expression takes into account the fixed payment of $[tex]250[/tex] for the band's performance and an additional $2 for each ticket sold. By multiplying the number of tickets sold (x) by $2 and adding it to the fixed payment, we can calculate the band's total earnings.

The equation for the cost of the television without remote control is  x = 649 + 125 and its solution is $774.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

Cost of television with remote control = $649

It is also given that this amount is $125 more than the cost without remote control.

Suppose x be the cost of television without remote control.

Thus, x = 649 + 125

⇒ x = 774

Thus, the equation for the cost of the television without remote control is  x = 649 + 125 and its solution is $774.
