Answer:

\sqrt[3]{7}

Step-by-step explanation:

here \: the \: power \: of \: 7 \: is \: 3 \\ the \: cube \: represented \: by \: the \: radical \: sign \: with \: number \: 3 \\  \sqrt[3]{x}    =cube \: root \: . \\ so \: we \: can \: write \: the \: given \: expression \ \: as \:   \\ \: 7 \times \frac{1}{3}  =  \sqrt[3]{7}  \\ thus \:   \: the \: ans \: is \: a. \:  \sqrt[3]{7}

The length of a living room is 12 feet and its width is 1012 feet. The length of the room is being expanded by x feet. Choose an
Ivanshal [37]

Answer:

Option C. 10.5(12 + x) square feet

Option E. (126 + 10.5x) square feet

Step-by-step explanation:

step 1

Find the area of the original living room

we know that

The area of the original living room is equal to

A=LW

we have

L=12\ ft\\W=10\frac{1}{2}\ ft=10.5\ ft

substitute

A=(12)(10.5)=126\ ft^2

step 2

Find the new area of the living room

The length of the room is being expanded by x feet

so

we have

L=(12+x)\ ft\\W=10.5\ ft

The new area is

A=10.5(12+x)\ ft^2

The expanded form of the expression is

Apply distributive property

A=10.5(12)+10.5(x)\\A=(126+10.5x)\ ft^2

2. Determine if either of the following equations are functions? Draw the graphs and explain how
nekit [7.7K]

Answer:

Both equation represent functions

Step-by-step explanation:

The function is the relation that for each input, there is only one output.

A. Consider the equation

y=-\dfrac{3}{5}x+2

This equation represents the function, because for each input value x, there is exactly one output value y.

To check whether the equation represents a function, you can use vertical line test. If all vertical lines intersect the graph of the function in one point, then the equation represents the function.

When you intersect the graph of the function y=-\dfrac{3}{5}x+2 with vertical lines, there will be only one point of intersection (see blue graph in attached diagram). So this equation represents the function.

B. Consider the equation

y=x-x^2

This equation represents the function, because for each input value x, there is exactly one output value y.

When you intersect the graph of the function y=x-x^2 with vertical lines, there will be only one point of intersection (see green graph in attached diagram). So this equation represents the function.

ok more of a question not like a equation or anything but when do you know when there is a extraneous answer and how do you solv
Likurg_2 [28]

One can know if an equation is extraneous if after plugging it in the original equation, it shows a false meaning or the value is undefined.

<h3>What is an extraneous equation?</h3>

It should be noted that an extraneous equation means a root of a transformed equation that isn't the root of the original equation due to the fact that it's excluded from the domain of the original equation.

In this case, one can know if an equation is extraneous if after plugging it in the original equation, it shows a false meaning or the value is undefined.
