Answer:
(x, y) = (1, -9)
Step-by-step explanation:
y = -9x
-8x-6y = 46
By substituting the value of y (first equation) into the second equation, we get,
-8x - 6*(-9x) = 46
-8x + 54x = 46
46x = 46
x = 1.
So, y = -9
The answers are 2i/15 and -2i/15. The work is attached below
3/8=2/4c+10
Multiply all terms by c and cancel:
3c/8=24+10c
(Simplify both sides of the equation)
3/8c=10c+24
(Subtract 10c from both sides)
3/8c−10c=10c+24−10c
−77/8c=24
(Multiply both sides by 8/(-77))
(8/−77)*(−77/8c)=(8/−77)*(24)
c=−192/77
Answer:
$7.45
Step-by-step explanation:
If it's constant , divide the amount he earns by the amount of hours. It should be the same every time.
44.70 divided by 6=7.45
