Let A = {2,3) and B = {2,3,4}. If a relation from A to B is defined by R = {(x, y) :x + y = 5), find R. a) R = {(x, y) : x + y = 5}
b) R = {(x, y) = x + y = 6)
c)R= {(x, y) : y = x^2}
d) R = {(x, y) : x=y}
​

Step-by-step explanation:

Finding cartesian product :

A×B

= {2,3} × {2,3,4}

= {(2,2),(2,3),(2,4),(3,2),(3,3),(3,4)}

so

R = {(x,y):x+y=5}

so, R1 ={(2,3),(3,2)}

b) - R2 = {(2,4),(3,3)}

c) - R3 = {(2,4)}

d) - R4 = {(2,2),(3,3)}

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
