Answer:
a0 = 4
Step-by-step explanation:
- 6xy^-2/x^-3 =
- 6xx^3/y^2 =
- 6x^4/y^2
- a0 = 4
Numerator:
315= 3^2* 5* 7
Denominator:
1575= 3^2* 5^2* 7
Therefore,
315/1575
= (3^2* 5* 7)/ (<span>3^2* 5^2* 7)
= 1/5

Answer:
(x, y) = (5, 4)
Step-by-step explanation:
Subtracting the second equation from the first eliminates the x term.
(4x +6y) -(4x +2y) = (44) -(28)
4y = 16 . . . . simplify
y = 4
Using the second equation to find x, we have ...
4x +2(4) = 28
x + 2 = 7 . . . . . . divide by 4
x = 5 . . . . . . . . . subtract 2
The solution is (x, y) = (5, 4).
