Answer:
2
Step-by-step explanation:
15/3=5
25/5 = 5
10/2 = 5
You have to find the "pattern."
for 15 and 3, you have to divide 15 by 5 and thats 3.
for 25 and 5, 25/5 is 5, so 10/5 is 2.
one solution, y=0, x = 1.5
3y = -6x + 9
y = -6x +9
10 +15-14 -21 is the answer (option 2)
you use the foil method to multiply it out :)
