Using proportions, it is found that Talisa's error was at calculating the cost per minute of the game.
In the function:
- The input is x, which is the number of minutes.
- The output is f(x), which is the cost of playing the game for x minutes.
Talisa's expression is given by:
The cost of using a game facility is <u>$1 for every 12 minutes</u>, hence, the cost per minute is:
And the correct expression for the cost is:
Hence, it can be seen that Talisa's error was at calculating the cost per minute of the game.

Answer:
420 Mile's.
Step-by-step explanation:
First you figure out the unit rate by dividing 360 by 6 which is 60. So that's 60 miles per hour. Now multiply 60 by 7 to find out how many miles she will drive in 7 hours. When you multiply you get 420.
The correct answer is 1.
So, circle the 0 after the equals sign because the equation does not equal 0.
Anything raised by the power of 0 is 1.
This is known as the zero exponent rule :)
8/8 is bigger than 3/4 because 8/8 is equivalent to 1 and 1 is bigger than 3/4.
Let's eliminate x. To achieve this, mult. the 2nd equation by 2, obtaining
-8x + 2y = 10. Now add this result to the first equation:
8x-2y= -10
-8x + 2y = 10
---------------------
0
The two equations actually represent the same line. Without an x- or a y-value, we cannot solve for the value of the other variable. There are infinitely many solutions.
