Solve for x: 3x−2=8x+8

Answers

Answer 1

Answer:

-2 =x

Step-by-step explanation:

3x−2=8x+8

Subtract 3x from each side

3x-3x−2=8x-3x+8

-2 = 5x+8

Subtract 8 from each side

-2-8 = 5x+8-8

-10 = 5x

Divide each side by 5

-10/5 = 5x/5

-2 =x

Answer 2

Answer:

-2

Step-by-step explanation:

Subtract 8x from both sides.

3x−2−8x=8x+8−8x

−5x−2=8

Step 2: Add 2 to both sides.

−5x−2+2=8+2

−5x=10

Step 3: Divide both sides by -5.

−5x

−5

=

10

He repartido mi colección de canicas entre mis tres amigos. A thales le he dado 1/5 del total, a arquimedes un 1/3 del resto y por último a pitagoras le he regalado las 16 canicas que me quedaban

Answers

Answer:

Ok, supongamos que en total hay N canicas.

1/5 de esas canicas se le dieron a Thales.

Entonces el resto ahora es:

1 - 1/5 = 4/5.

1/3 de esas canicas se le dieron a Arquimedes.

Entonces Arquimedes recibe:

(1/3)(4/5) = 4/15 de las canicas totales.

El resto, que eran 16, se le dieron a Pitagoras.

Ahora, las dos primeras entregas fueron:

1/5 + 4/15 = 3/15 + 4/15 = 7/15.

El resto seria:

1 - 7/15 = 8/15.

Y sabemos que el resto es igual a 16 canicas, entonces tenemos que:

(8/15)*N = 16.

De aca podemos calcular el numero total de canicas.

N = 16*(15/8) = 30

Esto quiere decir que inicialmente hay 30 canicas.

Thales recibe 30*(1/5) = 7 canicas.

Arquimedes recibe 30*(4/15) = 8 canicas.

Pitagoras recibe 16 canicas.

Emily is thinking of a number, which she calls n. She finds 1/4 of the number and then subtracts 3.

Answers

Answer:

n/4 - 3 OR 1/4n - 3

Step-by-step explanation:

First, let's assign a variable to Emily's number.  Let is be x.

Now all we have to do is go through the problem step by step.

"She finds 1/4 of the number..."

There are two ways you can do this.  You can either multiply n by 1/4 (1/4n), or you can divide by 4 (dividing by four is the same as finding 1/4 of a number).  For this example let's divide by four

n/4

"...and then subtracts 3."

All we have to do is subtract 3 from n/4

n/4 - 3

REMEMBER: like I said, there are two possible options.  You can either have n/4 or 1/4n. They mean the same thing

Answer:

d is the correct answer i believe is right

The function (f·g)(x) is -2x³-8x²and the function (g·f)(x) is -2x³-8x². Therefore, the correct answer is option A.

What is the function?

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The given functions are f(x)=-2x² and g(x)=x+4.

Now, (f·g)(x)=f(x)×g(x)

= -2x² ×(x+4)

(f·g)(x)= -2x³-8x²

Here, (g·f)(x)=g(x)×f(x)

= (x+4)×(-2x²)

(g·f)(x)= -2x³-8x²

Therefore, option A is the correct answer.

2x^3 + 3x^2 -11x -6 divided by x - 2

p(x)= x-2

g(x)= 2x^3 + 3x^2 - 11x - 6

first we have to find the zero of the polynomial of x-2

p(x)= x-2 = 0

therefore,

p(x)= 2x^3 + 3x^2 - 11x - 6

p(2)= 2*2^3 + 3*2^2 - 11*2 - 6

Answer:

l=-15t+120

Step-by-step explanation:

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.

The equation represents representing the amount L owed after t weeks.

L = 120 - 15t

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,

Total amount borrowed = $120

Amount left to pay after 2 weeks = $90

This means,

In 2 weeks the amount paid.

= 120 = 90

= $30

The amount paid per week is constant.

2 week = $30

Divide both sides by 2.

1 week = $15

Now,

The equation represents representing the amount L owed after t weeks.

L = 120 - 15t

Thus,

The equation represents representing the amount L owed after t weeks.

L = 120 - 15t

Laura bought 55 shares of stock for $3.50 per share last year. She paid her broker a 1% commission. She sold the stock this week for $2 per share, and paid her broker a $10 flat fee. What were Laura’s net proceeds? Round to the nearest cent. What was her capital gain or loss?

Answers

Answer:

cp of 55 shares = 3.50 * 55 = 192.5

commission amount = 1% *192.5 = 1.925

Total invest = 192.5 + 1.925 = 194.425

sp of 1 share = 2

sp of 55 share = 2*55 = 110

Earning from shares = 110

since earning is less than invest, Laura has loss of (194.425 - 110) = 84.425

Laura has a loss of $84.425 for the cost price of $192.5.

What is an expression?

Mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Cost price of 55 shares = 3.50 x 55 = 192.5

Commission amount = 1% *192.5 = 1.925

Total invest = 192.5 + 1.925 = 194.425

The selling price of 1 share = 2

The selling price  of 55 share = 2*55 = 110

Earning from shares = 110

Since earnings are less than investment, Laura has a loss of (194.425 - 110) = $84.425

Therefore, Laura has a loss of $84.425 for the cost price of $192.5.
