Answer:

W = 20 (woman's age)

M = 60 (man's age)

Step-by-step explanation:

M = Man's age

W = Woman's age

M + 20 = 2(W + 20)

Sub for M

3W + 20 = 2W + 40

W = 20 (woman's age now)

M = 60 (man's age now)

lbvjy [14]

Step-by-step explanation:

n(A) is the number of elements is A, sometimes written |A|.  I count 7.  n(A)=7

13 is among the elements of A, so 13 ∈ A  is TRUE

26 is among the elements of A, so 26 ∉ A   is FALSE

10 isn't in A, so 10 ∉ A  is TRUE

Hey can you please help me posted picture of question
Maksim231197 [3]
For this case we have the following equation:
 y = x2-4x + 3
 Deriving we have the following equation:
 y '= 2x-4
 We equal zero and clear x:
 2x-4 = 0
 x = 4/2
 x = 2
 Substituting in the given equation we have:
 y = (2) ^ 2-4 (2) +3
 y = 4-8 + 3
 y = -1
 The vertex will be the ordered pair:
 (x, y) = (2, -1)
 Answer:
 
(x, y) = (2, -1)
