2(y - 3) = 20(x - 1)
(h, k) = (1, 3)
(y - 3) = 10(x - 1)
4p = 10
p = $\frac{5}{2}$
x = h - p
x = 1 - $\frac{5}{2}$
x = - $\frac{3}{2}$
Hope that helped! If it's wrong, I'm sorry; I only learned about directrix today.

PLZ HELP! Need this ASAP! Thx so much! Find m∠PMK Plz show ur work!

In ∆MKP and ∆MNP

MK = MN

PK = NP

MP = MP

SO ∆MKP AND ∆MNP ARE CONGRUENT.

SO m<PMN = m<PMK

m<NMK = 50

=> m<PMN + m<PMK = 50

=> 2 m<PMK = 50

=> m<PMK = 50/2 = 25°

Prove that if m, d, and k are integers and d > 0, then (m + dk) mod d = m mod d.

masya89 [10]

From the rules of modular arithmetic, (A+B)mod C= (A)modC +(B)modC

So, (m + dk) mod d = (m) mod d+ (dk) mod d

clearly (dk) mod d = 0, as one of the things (dk) mod d represents, is the remainder of dk, when divided by d, which is clearly 0.

Thus

(m + dk) mod d = (m) mod d+ (dk) mod d= (m) mod d+ 0=(m) mod d

(m + dk) mod d =(m) mod d
