6r+5 inches:

18r^2 - 27r - 35 = (3r-7) ( ) some unknown number.

You can use simple factoring to find the unknown factor by finding the other factor in the constant term and the squared term:
-7 times _ is -35; _ is positive 5
3r times __ is 18r^2; _ is 6r

That means the unknown factor, or the other side, is 6r+5 inches.

Hope that helps.

What is the value of x in the equation 2x + 3y = 36, when y = 6?
amm1812

Answer:

9

Step-by-step explanation:

When plugging 6 in for y, you get  

2x + 3(6) = 36

You have to multiply 3 and 6, getting

2x + 18 = 36.

Now, you subtract 18 from both sides to isolate the x variable, getting

2x = 18

Now, you divide 2 from both sides because we want x standing by itself, getting

x = 9

Therefore, your answer is 9.

Hope this helped

The cost of using a game facility is $1 for every 12 minutes. Talisa writes the function for the cost per hour as ()=. Explain T
Anna [14]

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:

f(x) = 12x

The cost of using a game facility is <u>$1 for every 12 minutes</u>, hence, the cost per minute is:

c = \frac{1}{12}

And the correct expression for the cost is:

f(x) = \frac{x}{12}

Hence, it can be seen that Talisa's error was at calculating the cost per minute of the game.
