Answer:
(P, Q) = (-75, 57)
Step-by-step explanation:
The equation will have infinitely many solutions when it is a tautology.
Subtract the right side from the equation:
Px +57 -(-75x +Q) = 0
x(P+75) +(57 -Q) = 0
This will be a tautology (0=0) when ...
P+75 = 0
P = -75
and
57-Q = 0
57 = Q
_____
These values in the original equation make it ...
-75x +57 = -75x +57 . . . . . a tautology, always true
Answer:
16 hours
Step-by-step explanation:
company A $800 plus $16 per hour
company B $720 plus $21 per hour
im going to start with 10 and go from there
company A
16 x 10 = 160
800 + 160 = 960
company B
21 x 10 = 210
720 + 210 = 930
it needs to go up so lets try 15
company A
16 x 15 = 240
800 + 240 = 1040
company B
21 x 15 = 315
720 + 315 = 1035
one more maybe 16
company A
16 x 16 = 256
800 + 256 = 1056
company B
21 x 16 = 336
720 + 336 = 10 56
