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:
6x -5y = 6
Step-by-step explanation:
You can use the 2-point form of the equation of a line to find it.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (6-0)/(6-1)(x -1) +0
y = 6/5(x -1) . . . . . . point-slope form
y = (6/5)x -6/5 . . . . slope-intercept form
5y = 6x -6
6x -5y = 6 . . . . . . . standard form
15-4X=-10-11X
-4X+11X=-10-15
7X=-25
X=-25/7
that's what it is
Answer:
D ; 3 hours, 45 minutes
Step-by-step explanation:
Answer: p=11.2
Step-by-step explanation:
14.3p- 32.24 =127.92
14.3p - 32.24 + 32.24 = 127.92 + 32.24
14.3p = 160.16
p = 160.16 ÷ 14.3
p = 11.2
Hope this can help you :)
