Answer:
GCF= 15
Step-by-step explanation:
The factors of 75 are: 1, 3, 5, 15, 25, 75
The factors of 165 are: 1, 3, 5, 11, 15, 33, 55, 165
Then the greatest common factor is 15.
(0,-12) is the y intercept
Answer:
(2,3)
Step-by-step explanation:
Because both equations involve the y-term -4y, elimination by addition/subtraction is a good choice as we solve this system of linear equations.
Multiply the 1st equation by -1, obtaining -x + 4y = 10; then add the 2nd equation to this result:
-x + 4y = 10
2x - 4y = -8
-------------------
x = 2
Next, find y. Substitute 2 for x in the first equation: 2 - 4y = -10. Subtract 2 from both sides, obtaining -4y = -12. Then y = 3.
The solution is (2,3).
