When solving Systems of linear equations, sometimes there is one solution,and sometimes there infinite solutions. Why does this happen?

Answers

Answer: If you were to graph the solution it would be evident. One solution is when the lines meet at one point, no solution is when the lines are parallel to each other (they do not touch) and infinitely solutions happens when the two lines are on top of each other.

Which of the following tables of values represent ordered pairs for the function f(x) = 2x – 1?x 3 6 9 12
f(x) 6 12 18 24

x 2 4 6 8
f(x) 5 9 13 17

x 1 2 3 4
f(x) 1 3 13 17

x 0 4 8 12
f(x) -1 7 15 23

Answers

The answer is A because x = 1/2 meaning that X is always going to be half of Y

Final answer:

The correct table of values that represents the function f(x) = 2x − 1 for the given values of x is the one with x values 0, 4, 8, 12 and corresponding f(x) values of -1, 7, 15, 23.

Explanation:

To determine which table of values represents ordered pairs for the function f(x) = 2x − 1, we need to check each pair of x and f(x) to see if they satisfy the equation. Let's examine each table:

  • x = 3; f(x) should be 2(3) − 1 = 5, but the table shows 6.
  • x = 2; f(x) should be 2(2) − 1 = 3, and the table shows 5 which also incorrect.
  • x = 1; f(x) should be 2(1) − 1 = 1, but the table shows 1 which is correct. Let's check the rest: for x = 2, f(x) = 3, which matches the table. However, for x = 3, f(x) should be 5, not 13 as listed in the table. So, this table is also incorrect.
  • x = 0; f(x) should be 2(0) − 1 = -1, which matches the table. For x = 4, f(x) = 7 confirms the table. The pairs for x = 8 and x = 12 also match the function. Therefore, the last table correctly represents the function f(x) = 2x − 1 for the given values of x.

The correct table of values for the function f(x) = 2x − 1 is the one that correctly corresponds for all x's:

  • x: 0 4 8 12
  • f(x): -1 7 15 23

A ferris wheel can accommodate 54 people in 24 minutes. How many people could ride the ferris wheel in 2 hours? What was that rate per hour?

Answers

The number of people rides the Ferris wheel in 2 hours is 270.

What is multiplication?

The basic explanation of multiplication is adding a number, with respect to another number, repeatedly.

Given,  Ferris wheel can accommodate 54 people in 24 minutes

number of people can ride in 1 minute = 54/24

number of minute in 2 hours is 2 x 60 = 120 minutes

no. of people can ride in 2 hours or 120 minutes is

54/24 x 120 = 270

Hence, the 270 people could ride the Ferris wheel in 2 hours.
