Say that a and b are integers, a ≡ 11 (mod 19), and b ≡ 3 (mod 19). find the integer c with 0 ≤ c ≤ 18 such that a. c ≡ 13a (mod 19).
b. c ≡ 8b (mod 19).
c. c ≡ a − b (mod 19).
d. c ≡ 7a + 3b (mod 19).
e. c ≡ 2a2 + 3b2 (mod 19). f ) c ≡ a3 + 4b3 (mod 19).

the answer is somewhere there guys it really . there im just not gonna answer

step-by-step explanation:

but i'm guessing ur first option tho

i belive those are the ones that are under 90 degreese.

i believe that the slope of the line is -5

step-by-step explanation:

i believe that the answer is

b. y-1=-2(x-4)

hope this !
