9+6=15 and 15-12=3 so this =3 the -(-6) becomes positive
The answer is below. X is greater than 8 and smaller than 24.
Answer:
dirk =13.25 hours
charlie =11 75 hours
Step-by-step explanation:
c+d=25------(1)
d-1.5=c-----(2)
from (1),
c+d=25
c=25-d-----(3)
substitude (3) into (2)
d-1.5=c
d-1.5=25-d
2d=26.5
d=13.25
if d=13.25 hours
c+d=25
c+13.25=25
c=25-13.25
c=11.75

Then how does that work
Step-by-step explanation:
Answer: m = - 3 and b = - 3.
Justification:
A system of linear equations will not have solutions if the two lines are parallel.
Two equations are parallel if their slopes (m) are equal and the y-intercep (b) are different.
Since the given equation is y = - 3x + 5, the value of m of the other equation, y = mx + b, in order to make a system with no solution, needs to be - 3, and the value of b need to be different to 5.
The only pair from the choices that meets that is the first option m = - 3 and b = -3.
