Answer:

a b and c

Step-by-step explanation:

a) a number is divisible by 3 if the sum of its dígits is divisible by 3:

3+4+5+1+5=18

<em>18 is divisible by 3 (6*3=18), then 34515 is divisible by 3 too.</em>

b)a number is divisible by 9 if the sum of its dígits is divisible by 9:

3+4+5+1+5=18

<em>18 is divisible by 9 (9*2=18), then 34515 is divisible by 9 too.</em>

c) a number is divisible by 5 if its last digit is 5 or 0

then, <em>34515 is divisible by 5</em>

Which line has the equation 2x - 3y = 6?<br> (Please explain how you got your answer)
notsponge [240]
First, isolate y:
2x - 3y = 6
-3y = -2x + 6
3y = 2x - 6
y = 2/3x - 2
That means that the line passes through the point (0, -2) and has a positive slope of 2/3. So it would be choice A because the line in choice A passes through the point (1, -2) and has a positive slope. Choice D also passes through the point (0, -2) but has a negative slope so it cannot be the correct answer.
Choice A is correct.
