If f(x) = 5x – 4 and g(x) = 4x + 1, find (f – g)(x). a. 9x – 5 b. 9x – 3 c. 5 – x d. x – 5

(f – g)(x) = f(x) - g(x) = (5x – 4) - (4x + 1)= 5x - 4 - 4x - 1 = x - 5

Answer is D. (x-5).

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
