Solve for x
Liula [17]

Answer:

  x = {-4, 4}

Step-by-step explanation:

Subtracting 3 gives ...

  5x^2 = 80

Dividing by 5, we get ...

  x^2 = 16

Taking the square root gives the solutions ...

  x = ±4

The smaller value of x is -4; the larger value is 4.

The first- and second-year enrollment values for a technical school are shown in the table below: Enrollment at a Technical Scho
pav-90 [236]

Answer:

  • <u><em>The solution to f(x) = s(x) is x = 2012. </em></u>

Explanation:

<u>Rewrite the table and the choices for better understanding:</u>

<em>Enrollment at a Technical School </em>

Year (x)       First Year f(x)      Second Year s(x)

2009                  785                        756

2010                   740                        785

2011                    690                        710

2012                   732                         732

2013                   781                          755

Which of the following statements is true based on the data in the table?

  • The solution to f(x) = s(x) is x = 2012.
  • The solution to f(x) = s(x) is x = 732.
  • The solution to f(x) = s(x) is x = 2011.
  • The solution to f(x) = s(x) is x = 710.

<h2>Solution</h2>

The question requires to find which of the options represents the solution to f(x) = s(x).

That means that you must find the year (value of x) for which the two functions, the enrollment the first year, f(x), and the enrollment the second year s(x), are equal.

The table shows that the values of f(x) and s(x) are equal to 732 (students enrolled) in the year 2012,<em> x = 2012. </em>

Thus, the correct choice is the third one:

  • The solution to f(x) = s(x) is x = 2012.

On his way to the park, Nathan rides his bike at a rate of 0.50 mile per minute for 3 minutes. He stops to admire an antique car
TiliK225 [7]

Answer and Step-by-step explanation:

Although the question is not complete, but with the context of the question, they are most likely going to ask for the total distance travelled or the total time or speed. So let's work on that.

Total time travelled = (3 + 5 + 4) = 12mins

Total speed travelled = (0.50 + 0.00 + 0.40)miles/min = 0.90mile/min

The 0.00 represents the period he was at rest admiring an antique car. At this moment, he was not moving so his speed is 0.

Total distance travelled = total speed x total time = 0.90miles/min x 12min = 10.8miles
