X would equal -3. 5x-3 would equal -15, and 2 negatives would equal a positive. So, -15+3 would equal -12.

Suppose that S is the set of successful students in a classroom, and that F stands for the set of freshmen students in that clas
lora16 [44]

Answer:

b) 24

Step-by-step explanation:

We solve building the Venn's diagram of these sets.

We have that n(S) is the number of succesful students in a classroom.

n(F) is the number of freshmen student in that classroom.

We have that:

n(S) = n(s) + n(S \cap F)

In which n(s) are those who are succeful but not freshmen and n(S \cap F) are those who are succesful and freshmen.

By the same logic, we also have that:

n(F) = n(f) + n(S \cap F)

The union is:

n(S \cup F) = n(s) + n(f) + n(S \cap F)

In which

n(S \cup F) = 58

n(s) = n(S) - n(S \cap F) = 54 - n(S \cap F)

n(f) = n(F) - n(S \cap F) = 28 - n(S \cap F)

So

n(S \cup F) = n(s) + n(f) + n(S \cap F)

58 = 54 - n(S \cap F) + 28 - n(S \cap F) + n(S \cap F)

n(S \cap F) = 24

So the correct answer is:

b) 24

Find the product. Write your answer in<br> exponential form.<br> 6^-4•6^0
IRINA_888 [86]

Answer: 6^-4

Step-by-step explanation:

6^-4•6^0

According to the law of indices, anything raised to a power of 0 is 1

So, for 6^-4•6^0

(6^0) = 1

Then, 6^-4•6^0

= 6^-4•1

= 6^-4

Since, according to law of indices anything raised to a negative power is made a denominator

= 1/(6^4)

= 1/1296

Thus, the answer is 1/1296, but in exponential form it is 6^-4
