Hãy xác định giá và lượng cân bằng của thị trường có ba hàng hóa với các hàm cung và hàm cầu của mỗi loại hàng hóa như sau:
- Hàng hóa 1: Qs1 = 3p1, Qd1 = 120 − p1 + p2 + 2p3
- Hàng hóa 2: Qs2 = −10 + 2p2, Qd2 = 150 + p1 − 2p2 + p3
- Hàng hóa 3: Qs3 = −20 + 5p3, Qd3 = 250 + 2p1 + 2p2 − 3p3

step-by-step explanation:

y > 1/3x

y < = -x + 4

hope this : )

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
