Solve |2x + 2| = 10

Mathematics
1 answer:
Vladimir [108]2 years ago
5 0

Answer:

x = - 6 , x = 4

Step-by-step explanation:

the absolute value function always gives a positive value but the expression inside can be positive or negative , that is

2x + 2 = 10 or - (2x + 2) = 10

solving both

2x + 2 = 10 ( subtract 2 from both sides )

2x = 8 ( divide both sides by 2 )

x = 4

or

- (2x + 2) = 10

- 2x - 2 = 10 ( add 2 to both sides )

- 2x = 12 ( divide both sides by - 2 )

x = - 6

Mean: Add all the numbers and divide by the amount of numbers.

20 + 0 + 7 + 10 + 11 + 0 + 25 + 15 + 1 = 89
89/9 = 9.889 (rounded)

Mean = 9.889 (rounded)

Median: Reorder from least to greatest, and the middle number is the median.
0, 0, 1, 7, 10, 11, 15, 20, 25

The middle number is 7

Median = 7

Mode: The number that shows up the most.
Mode = 0, which shows up one time more than all the other numbers

Range: Subtract the greatest number with least number

25 - 0 = 25

Range = 25
