Answer:

$\large\boxed{B\subset A}$

Step-by-step explanation:

$\O\subset A-\bold{TRUE}\ \text{because the empty set is a subset of any set}\\\\B\subseteq B-\bold{TRUE}\ \text{because}\ B=B\\\\B\subset A-\bold{FALSE}\ \text{because}:\\\\A=\{4,\ 7,\ 10,\ 13,\ 17\},\ B=\{3,\ 5,\ 7,\ 9\}\\\\3\notin A,\ 5\notin A\ \text{and}\ 9\notin A\\\\\text{For}\ B\subset A\ \text{, each element of set B must be in set A.}$

Is 3(-4y) equivalent to 6-4y

Leokris [45]

3(-4y)=6-4y

-12y=6-4y

-8y=6

y=-3/4

So the two expressions are equivalent, if and only if y = -3/4.

What is the value of f(3) in the function f(x)=5/6x+8

natita [175]

For this case we have a function of the form $y = f (x)$ , where $f (x) = \frac {5} {6} x + 8$

We must find the value of the function when $x = 3$ , that is, we must find f (3). So:

$f (3) = \frac {5} {6} (3) + 8\\f (3) = \frac {15} {6} +8\\f (3) = \frac {5} {2} +8\\f (3) = 2.5 + 8\\f (3) = 10.5$

So $f (3) = 10.5$

Answer:

$f (3) = 10.5$

Square 24-×whenx=6. Write in radical form

Delicious77 [7]

Answer:

√ 18 = 3 √2

Step-by-step explanation:

So 24-6 is 18 and then the square root of that. You have to divide by a perfect square and the largest perfect square that can go into 18 is nine because 3x3. 9 can go into 18 2 times so it is 2 radical 9
