7y - 3x = -5
-3x = -7y - 5
x = 7/3y + 5/3
Answer:
- (x -1)(x +6)
- (x -5)(x +3)
- (x -4)(x -3)
Step-by-step explanation:
In each case, you're looking for divisors of the constant that have a sum equal to the x-coefficient. Those divisors are the constants in the binomial factors.
1) -6 = -1·6 = -2·3 . . . . . (-1)+(6) = 5, so these are the constants of interest.
x^2 +5x -6 = (x -1)(x +6)
__
2) -15 = -1·15 = -3·5 = -5·3 . . . . . (-5)+(3) = -2, so these are the constants of interest
x^2 -2x -15 = (x -5)(x +3)
__
3) 12 = -1·-12 = -2·-6 = -3·-4 . . . . . (-3) +(-4) = -7, so these are the constants of interest
x^2 -7x +12 = (x -3)(x -4)
Answer:
x = 7 x = -7
Step-by-step explanation:
n^2 - 49 = 0
+49 +49
n^2 = 49

Answer:
4
Step-by-step explanation:
you're just going to plug in 15 where f is so its asking 15-11 which would be four
Answer:
incorrect
2 1/2 divided by 3/4
2 1/2 divided by 3/8 = 6 2/3
6
hope that helped i checked it over im positive its correct
