Answer:
I'm not sure what 15y3 is, but I'll take a guess.
If the only numbers are 15, 3, and -40, then the greatest common factor is 1.
If the only numbers are 15 and 3, then it's three.
If the only numbers are 15 and -40, it would be 5.
Answer:
3 - 151 x
Step-by-step explanation:
d/dx(5×3 x - 10×15 x - 3 x - 10 x - (3 x - 3)) = -151
Indefinite integral:
integral(3 - 151 x) dx = 3 x - 75.5 x^2 + constant
Definite integral after subtraction of diverging parts:
integral_0^∞ ((3 - 151 x) - (3 - 151 x)) dx = 0
Answer:
It has a single solution x=-3 y=26
Step-by-step explanation:
The ratios of coefficients of x and y are different, so the pair of equations has one solution. It is easy to tell the first offered solution (15, 17) does not satisfy the first equation, so that choice is eliminated.
Fortunately, the second offered solution, (x, y) = (-3, 26), satisfies both equations.
The equations have a single solution: (x, y) = (-3, 26).
