Answer:
relation between X and Y is just nothing both are same
6)
91 is a composite number because it's divisible by 7 and 13
7)
477 is divisible by 3 and 9, since the sum of its digits (18) is divisible by 3 and 9 ( or the sum is a multiple of 3 and 9) .Not divisible by 6
8)
348:is divisible by 4 because the last 2 digits (48) are a multiple of 4
348:is NOT divisible by 5 because the last digit is neither 5 nor 0
348:is divisible by 6 because it's divisible by 2 and also by 3
9)
23624 is divisible by 8 because te last 3 digits (624) are divisible y 8
(624/8 =78)
None of the others are divisible by 8
10) A number is divisible by 6 IF IT'S DIVISIBLE BY 2 AND BY 3:
213 NO
468 is divisible by 2 since the last digit is divisible by 2. It's also divisible by
3 since the sum of its digits [18] is divisible by 3, hence 468 is divisible by 6
621 it's divisible by 3 but NOT by 2, then it's not divisible by 6
Answer:
7 : 11 is the right answer
Answer:
y=(x-2)²+2
Step-by-step explanation:
y=x²-4x+6 (a=1 , b=-4 , c=4)
vertex form : y=a(x-h)²+k
h and k are the vertex coordinate :
h=-b/2a =-4/-2
h=2
find f(2) to find k in the equation :x²-4x+6
(2)²-4(2)+6
4-8+6=2 (k=2)
vertex form : y=a(x-h)²+k (a=1)
y=(x-2)²+2
