Answer:
y = -3x
Step-by-step explanation:
It is easiest to try the answers for x=1.
a) y = 1/-3 = -1/3 ≠ -3
b) y = 1 ≠-3
c) y = 3(1) = 3 ≠ -3
d) y = -3(1) = -3 . . . . . this rule matches the table
We have been given an expression
. We are asked to factor the given expression by grouping.
First of all, we will make two groups of our expression as:

Now we will factor of greatest common factor from each group.


Now we will factor out common terms
as:

Therefore, the factorized form of our given expression would be
.

To divide 53 by 8 wont be possible so u find a number that when you multiply by 8 it gives u a number closer to 58 which is 8*6=48 i.e 53 divided by 8 is 6 rem, then to get the reminder you subtract 42 from 53 i.e 53–48=5 so the final answer will be 6 and 5/6

Answer:
480,700 sets (first choice)
Step-by-step explanation:
If all 25 questions are different,
When order of selection counts:
P(25,7)
= 25!/(25-7)!
= 15511210043330985984000000/6402373705728000
= 2422728000
When order of selection does not count count:
C(25,7)
=25!/(7!*(25-7)!)
=15511210043330985984000000/(6402373705728000*5040)
= 480,700
Hope this helps, have a nice day.
