Answer:
I'm thinking it's 9
Step-by-step explanation:
D = mV + C , ( compare this to your familiar y = mx + b)
when V=40, D=150
150 = 40m + C **
when V=54, D=192
192 = 54m + C ***
subtract ** from ***
42 = 14m
m = 3
sub into ** , 150 = 120 + C
C = 30
so you have D = 3V + 30
sub in your given value of V
Answer:
-4
Step-by-step explanation:
Absolute value is the distance from one number to the next, so it can't be negative. I-7+3I is 4.
- * 4 is equivalent to -1 * 5 so the answer is -4.
