Whould anyone mind helping please. The first box says 6.25x+12x=30.75 the second box says 6.25x+12=30.75 3rd box says 6.25x+30.7

Snowcat [4.5K]

Answer:

The correct equation is: 6x+12 = 30.75

And 3 people went to the movies

Step-by-step explanation:

We will write the equation to represent this scenario.

Let x be the number of people who went for movies.

Then the price of ticket for x people will be: 6.25x

They spent $12 on refreshments and a total of $30.75 so the equation will be:

$6.25x+12=30.75$

solving the equation will give us total number of people

So,

$6.25x+12 = 30.75\\6.25x = 30.75-12\\6.25x = 18.75\\\frac{6.25x}{6.25} =\frac{18.75}{6.25}\\x = 3$

Hence,

The correct equation is: 6x+12 = 30.75

And 3 people went to the movies

Identify the parent function that can be used to graph the function f(x)= (1/4 x)^3

Kaylis [27]

Answer:

$f(x)=x^3$

Step-by-step explanation:

The parent function denotes the simplest function (free from any horizontal/vertical stretch/compression) that represents a family of functions. In this case the term 1/4 indicates a horizontal stretch and should be removed to find the parent function of $f(x)=x^3$ . From here we're in simplest form, since $y=x$ or others represent a completely different family of functions and cannot be obtained from horizontal/vertical stretches/compressions.
