R is a point which is 13 units from the origin if its x co-ordinates is 12 find the possible values of the y co-ordinate

given (0,0) and (12,y1)

the distance formula states taht

the distance between the points (x1,y1) and (x2,y2) is

D=

given

D=13

x1=0, y1=0

x2=12

square both sides

minus 144 both sides

sqrt both sides

+/-5=y2

the points are

(12,5) and (12,-5)

Step-by-step explanation:

21

step-by-step explanation:

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
