  -14 ≤ x ≤ 20

Step-by-step explanation:

Left inequality:

  2(3 -x) +5 ≤ 39

  2(3 -x) ≤ 34 . . . . . subtract 5

  3 -x ≤ 17 . . . . . . . divide by 2

  3 -17 ≤ x . . . . . . . . add x-17

  -14 ≤ x

Right inequality:

  2(x -3) +5 ≤ 39

  2(x -3) ≤ 34 . . . . . . subtract 5

  x -3 ≤ 17 . . . . . . . . .divide by 2

  x ≤ 20 . . . . . . . . . . add 3

The solution is ...

  -14 ≤ x ≤ 20

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
