If 'a' and 'b' stand for true sentences and 'c' and 'd' stand for false sentences, what is the truth-value of each of the sentences represented below? (circle t' or 'f.) t f 1 c b t f 2. a c b. a t f 3. t f 4. b. c t f 5. c (b a) 6 (c b)a t f t f 7 (a. b).c 8 t f (c a) t 9. (c b) f 10 b.(c a) t f t f 11 (b a).d t f 12. c(a-d) 13. (bd) t f 14 t f (c.(b d)) 15. (bc) t f

i dont know sorry

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
