What is the solution to this absolute value equation

Answers

The answer is there is no solution.

Answer:

No solutions

Step-by-step explanation:

2 | x - 7 | = -4       We need to isolate the absolute value, so in order to do that we need to divide 2 from both sides of the equation.

| x - 7 | = -2

Absolute values can not be equal to a negative number.

Therefore, your answer is no solutions.

Answer:

The lines are parallel

Step-by-step explanation:

The slopes are the same

The equations are both written in slope intercept form

y = mx+b where m is the slope and b is the y intercept

-3/5 is the slope in both equations

When the slopes are the same the equations are parallel

They have different y intercepts, so they are different lines  ( if they have the same y intercept and same slope, they would be the same line)

How do you know if a set of information shows a proportional relationship? Select ALL that apply.

Answers

Answer:

(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .") This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

Answers

Answer:(6,14)

Step-by-step explanation: x+y≤22   &   .05+.10y≥ 1.40

y≤22-x                                                        y≥14- 1/2x

The system of the inequalities will be 0.05x + 0.10y ≥ 1.40 and x + y ≤ 22. And the graph is given below.

What is inequality?

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

Anna has a nickels and y dimes. She has at most 22 coins worth a minimum of $1.40 combined.

Let x be the number of nickels and y be the number of dimes. Then the equation is given as,

0.05x + 0.10y ≥ 1.40

x + y ≤ 22

The system of the inequalities will be 0.05x + 0.10y ≥ 1.40 and x + y ≤ 22. And the graph is given below.

What is equation?

Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal.

What is the function?

The function is defined as mathematics expression defines a relationship between one variable and another variable. When we say that a variable quantity y is a function of a variable quantity x, we indicate that y depends on x and that  value of x determines what value of  y  will be. This relationship can be expressed as follows: y = f (x)

Given the equation as:

(2x + 2)/y = 4w + 2

To determine the value of x

Multiply by y both sides

y × (2x + 2)/y = (4w + 2) × y

2x + 2 = 4wy + 2y

Subtract 2 from both sides

2x + 2 - 2 = 4wy + 2y - 2

2x = 4wy + 2y - 2

Divide by 2 both sides

x = (4wy + 2y - 2)/2

x =  4wy/2 +  2y/2 - 2/2

x = 2yw + y - 1

Hence, the value of x is 2yw + y - 1.
