Y = -2x - 5

lions [1.4K]

Answer:

A. One line

Step-by-step explanation:

Let rearrange the system of equations into explicit forms:

$y = -2\cdot x - 5$

$6\cdot x + 3\cdot y = -15$

$3\cdot y = -6\cdot x - 15$

$y = -2\cdot x - 5$

The second equation is identical to the first one, which means that there is just one line.

Answer:

(A - B)' = {2, 4, 5, 6, 7, 8, 9}

(A n B) = {2, 4}

Step-by-step explanation:

Given the set :

U = { 1 , 2 , 3 , 4 , 5 ,6 , 7 , 8 , 9 }

A={1 , 2 , 3 , 4 } , B= {2 , 4 , 6 , 8 }

(A - B) = elements of A which are not in B

(A - B) = {1, 3}

(A - B)' = the complement of A - B ; element in the universal set which are not in A - B

(A - B)' = {2, 4, 5, 6, 7, 8, 9}

(A n B) = elements in both set A and set B

(A n B) = {2, 4}
