Let X = {n ∈ N : 10 ≤ n < 20}. Find examples of sets with the properties below and very briefly explain why your examples work. (a) A set A ⊆N with |A| = 10 such that X \A = {10,12,14}.

(b) A set B ∈P(X) with |B| = 5.

(c) A set C ⊆P(X) with |C| = 5.

(d) A set D ⊆ X ×X with |D| = 5

(e) A set E ⊆ X such that |E|∈ E.

5x+2x=49

7x=49

x=7. 35 apples

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

i have no clue what you just said. write a question in english?
