I'm on a time which of the following represents a rotation of △pqr, which has vertices p(−2,4), q(−3,−9), and r(4,−2), about the origin by 180°? p (2, −4) q (3, 9) r (−4, −2) p (2, −4) q (−9, −3) r (−4, −2) p (2, −4) q (3, 9) r (−4, 2) p (−4, −2) q (9, −3) r (2, 4)

P = (2,-4)

Q = (3,9)

R = (-4,2)

Step-by-step explanation:

rotation by 180 degrees means that the points are inverted. the answers would be the opposite of the given

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
