In 1 * 4 + 7y, 7 is the coefficient of y. The coefficient of a variable is a constant (number) that is before the variable and multiplies itself and the variable. Since 7 is the number before y multiplying itself by y, 7 is the coefficient of y.

It is A. 2^12.
The question asks for the value of 8 to the x-power. Divided by 2 to the y-power. the trick to solving this is to rewrite 8^x as 2^3x. so you will have 2^3x divided by 2^y. since the bases are now the same , you can subtract the exponents to get the result of 2^3x-y. since it is given the 3x-y is 12. your final answer is 2^12

How can you set notation?<br> {3,8,6} is not a subset of {1,2,3,4,5,6}
8_murik_8 [283]

If A is a subset of B, then all elements from a set A are in a set B.

The number 8 from {3, 8, 6} is not in the set {1, 2, 3, 4, 5, 6}. Therefore {3, 8, 6} is not a subset of {1, 2, 3, 4, 5, 6}.

\{3,\ 8,\ 6\}\not\subset\{1,\ 2,\ 3,\ 4,\ 5,\ 6\}
