If you divided 48 objects into sets of 7, how many sets of 7 could you make, and how many are left over?

Answers

Answer:

Step-by-step explanation:

No. objects in one set = 7

Let there be n set

Then, No. objects in n set = 7*n = 7n

Given that total no of objects are 48

Thus,

7n = 48

n = 48/7 = (42+6)/7 = 42/7 + 6/7 = 6 + 6/7

n = 6 + 6/7

Thus, there will be 6 set which has 7 objects. fraction means one set is fraction 6/7 but set cannot be in fraction hence negating it.

Now, total objects in 6 sets = 6*7 = 42.

No. of objects left = 48 - 6 = 6

There goes my hopes for Virtuoso rank....What are the zeros of the function y = x2 + 10x – 171, and why?

A) The zeros are x = –19 and x = 9 because in factored form, the function is y = (x – 19)(x + 9)

B) The zeros are x = –19 and x = 9 because in factored form, the function is y = (x + 19)(x – 9).

C) The zeros are x = 19 and x = –9 because in factored form, the function is y = (x – 19)(x + 9).

D) The zeros are x = 19 and x = –9 because in factored form, the function is y = (x + 19)(x – 9).

Answers

y = x^2 + 10x - 171
y = (x - 9)(x + 19)

x - 9= 0 x + 19 = 0
x = 9 x = -19

Answer B covers all requirements... the factored form is
y= (x + 19)(x - 9)
and the zeros are -19 and 9
