Answer:

Step-by-step explanation:
1) find two factors of c that sum up to -2.
2) 5 and -7 are factors of -35 that sum up to -2.
3) (x+5)(x-7)
4) x+5= 0, x= -5
5) x-7= 0, x= 7
4) the two solutions are -5 and 7.
Answer:
181/12 or 15 1/12
Step-by-step explanation:
Answer:
6) 9216π
8) 24
Step-by-step explanation:
6)
V= 2/3πr³
r = 48/2 = 24
V = 2/3π24³
V = 9216π
8)
V = 4/3πr³
2304π = 4/3πr³
r³= (2304π)/4/3π
r³= 1728
![\sqrt[3]{r^3} =\sqrt[3]{1728}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Br%5E3%7D%20%3D%5Csqrt%5B3%5D%7B1728%7D)
r = 12
D = 2r
D = 2 x 12 = 24

Answer: The system forms the same line.
Step-by-step explanation:
3x - y = -2
-y = -3x - 2 (subtract 3x from both sides)
y = 3x + 2 (divide both sides by -1)
First equation: y = 3x +2
Second equation: y = 3x +2
THEY ARE THE SAME LINE —> there are infinitely many solutions.
