2. define a relation on r3 by (ri, 22,x3) ~ (34./2,0%) if and only if there show that is an exists ? 0 such that (zi, a2.x3) a(y1,u2,ys). show that ~ is an equivalence relation (reflexive, symmetric, transitive).

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

your answer is

a.

5
