Disregard the sign. Find the mean (add the numbers, and divide by the amount of numbers there are)

2 + 12 = 14/2 = 7

Add 7 (if you are going by -2), if you are starting from 12, subtract 7

-2 + 7 = 5

5 is your midpoint.

hope this helps

The equation is: (Note: Let the two numbers be x and y)

(x + y)/2 = midpoint

hope this helps

62÷4×12

then we work left to right for multiplication and division

62÷4

Anastaziya [24]

Answer:

Range:  [1,25]

Step-by-step explanation:

You may find it easier to express the domain in set notation rather than in words:  [1,9], or 1 ≤ x ≤ 9.  The smallest value of f(x) = 3x - 2 is at x = 1 and is 3(1) - 2, or 1.  The lasrgest value of f(x) is at x = 9 and is 3(9) - 2, or 25.

Thus, the range of this function is [1,25] or 1 ≤ y ≤ 25.
