Solve the absolute value equation (picture listed below)

Mathematics
1 answer:
STALIN [3.7K]2 years ago
3 0

Answer:

17) x = 0, -6

18) x = 2, -4

Step-by-step explanation:

Isolate the absolute value, then split into 2 equations and solve both

example: |x + 1| = 2

x + 1 = 2, x + 1 = -2

x = 1, -3

------------------------------------

17) |x + 3| - 1 = 2

isolate the absolute value:

|x + 3| = 3

x + 3 = 3, x + 3 = -3

x = 0, -6

-----------------------------------------

18) 3|x + 1| = 9

isolate absolute value:

|x + 1| = 3

x + 1 = 3, x + 1 = -3

x = 2, -4

Nine and one-half less than four and one-half times a number is greater than 62.5. Which of the following represents the solutio
madreJ [45]

Answer:

{16, +infinity}

Step-by-step explanation:

Represent the number with n

Required

Find the solution set

From the question, we have that;

4½n - 9½ > 62.5

Convert all numbers to decimal

4.5n - 9.5 > 62.5

Add 9.5 to both sides

4.5n - 9.5 + 9.5 > 62.5 + 9.5

4.5n > 72

Multiply both sides by 2

2(4.5n) > 72 * 2

9n > 144

Multiply both sides by ⅑

⅑ * 9n > 144 * ⅑

n > 16

This implies that n ranges to infinity from positive 16;

Hence, the correct answer is {16, +infinity}
