What is the value of the expression "two less than six times the difference of a number and five" when n = 9?

Burka [1]

Answer: The value of the expression when $n=9$ is $22$

Step-by-step explanation:

In this case, you need to remember that:

1. Tthe word "less than" indicates a subtraction.

2. By definition, the "Difference" in the result of a subtraction.

3. The word "times" indicates multiplication,

Based on the information given above, you know that " Six times the difference of a number and five" can be expressed as:

$6(n-5)$

Then, "Two less than six times the difference of a number and five" can be represented with this expression:

$6(n-5)-2$

Now you can substitute $n=9$ into the expression and the evaluate in order to find the value of the expression. This is:

$6(9-5)-2=6(4)-2=24-2=22$

Serhud [2]

Answer:

Follows are the solution to this question:

Step-by-step explanation:

Given:

$s_1 = 21 \ \ t_1 = 1\\\\s_2 = 59 \ \ t_2 = 2\\\\s_3 = 141 \ \ t_3 = 4$

All points are on the graph including its quadratic function, in order to install their coordinates to values of x and y with the following values:

$y= ax^2 + bx + c\\\\21=a+b+c$ Inserting the coordinates of the first point

$y= ax^2 + bx + c\\\\59 =4a+2b+c$ Inserting the coordinates of the second point

$y= ax^2 + bx + c\\\\141=16a+4b+c$ Inserting the coordinates of the third point
