Let's solve for x.

y=x−1

Step 1: Flip the equation.

x−1=y

Step 2: Add 1 to both sides.

x−1+1=y+1

x=y+1

Answer:

x=y+1

---------------------------------

Let's solve for x.

y=−2x−4

Step 1: Flip the equation.

−2x−4=y

Step 2: Add 4 to both sides.

−2x−4+4=y+4

−2x=y+4

Step 3: Divide both sides by -2.

−2x

−2

=

y+4

−2

x=

Leanne and her family plan to attend a symphony at an orchestra hall. Before booking the tickets, Leanne checked a website where
lord [1]

Using proportions, it is found that Leanne's family should book their tickets at Section U1 to maximize their chances of having a "perfect" view.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, the section with the highest proportion of perfect views should be chosen, hence:

pL1 = 57/90 = 0.633

pL2 = 33/52 = 0.635

pL3 = 47/75 = 0.623

PU1 = 55/84 = 0.655

pU2 = 27/43 = 0.628

pU3 = 22/35 = 0.629

Leanne's family should book their tickets at Section U1 to maximize their chances of having a "perfect" view.

Answer:

$3.98(estimated)

Step-by-step explanation:

3c (cake) + 2(2c - 11) (bread) = 5.87

3c + 4c - 22 = 5.87

7c - 22 = 5.87

7c = 5.87 + 22

7c = 27.87

c = 3.98

Determine the domain of the function (fog)(x) where f(x)=3x-1/x-4 and g(x)=x+1/x
Katarina [22]

Answer: (-∞,-1) ∪ (0,+∞)

Step-by-step explanation: The representation fog(x) is a representation of composite function, meaning one depends on the other.

In this case, fog(x) means:

fog(x) = f(g(x))

fog(x) = 3(x+\frac{1}{x} )-\frac{1}{x+\frac{1}{x} } -4

fog(x)=3x+\frac{3}{x} -\frac{1}{\frac{x^{2}+x}{x} } -4

fog(x)=3x+\frac{3}{x} -\frac{x}{x^{2}+x} -4

fog(x)=\frac{3x^{2}(x^{2}+x)+3(x^{2}+x)-x-4x(x^{2}+x)}{x(x^{2}+x)}

fog(x)=\frac{3x^{4}+3x^{3}+3x^{2}+3x-x-4x^{3}+4x^{2}}{x(x^{2}+x)}

fog(x)=\frac{3x^{4}-x^{3}-x^{2}+2x}{x(x^{2}+x)}

This is the function fog(x).

The domain of a function is all the values the independent variable can assume.

For fog(x), denominator can be zero, so:

x(x^{2}+x) \neq 0

If x = 0, the function doesn't exist.

x^{2}+x \neq0

x(x+1) \neq0

x+1\neq0

x\neq-1

<u>Therefore, the domain of this function is: </u><u>-∞ < -1 or x > 0</u>
