Answer:
Sorry this is late!
Step-by-step explanation:
Hello!
log₃(x) + log₃(x - 6) = log₃(7) <=>
<=> log₃(x * (x - 6)) = log₃(7) <=>
<=> log₃(x² - 6x) = log₃(7) <=>
<=> x² - 6x = 7 <=>
<=> x² - 6x - 7 = 0 <=>
<=> x² + x - 7x - 7 = 0 <=>
<=> x * (x + 1) - 7 * (x + 1) = 0 <=>
<=> (x + 1) * (x - 7) = 0 <=>
<=> x + 1 = 0 and x - 7 = 0 <=>
<=> x = -1 and x = 7, x ∈ { 6; +∞ } <=>
<=> x = 7
Good luck! :)
Answer:
Roster Form of M = {-2, -1 , 0, 1}
Set Builder Form of M = {x : x is an integer and -3 < x ≤ 1 }
Step-by-step explanation:
Roster Form: A set is said to be in roster form if each element of the set is written distinctly in the set with commas in between them.
Set Builder Form: A set is said to be in set builder form if all the set elements are represented by describing their properties.
Now, here M is the set of integers that are greater than -3 and less than or equal to 1.
So, by definition of the set forms,
Roster Form of M = {-2, -1 , 0, 1}
Set Builder Form of M = {x : x is an integer and -3 < x ≤ 1 }
the second one
reason:
the difference or the triangles is 1/3
