Good morning
Answer:
NO
Step-by-step explanation:
Here we just substitute x and y by their values and see if the inequality still true or not
y = 3
6x + 3 = 6(2) + 3 = 15
since 3 < 15 then the inequality y > 6x + 3 is wrong.

Answer:
A. -10
Step-by-step explanation:
Hi there!
We are given that the equation of line m is , and we want to find the slope of the line perpendicular to m
Perpendicular lines have slopes that multiply to get the result of -1
So let's find the slope of line m
The equation is written in the form y=mx+b, where m is the slope, and b is the y intercept
As is in the place of where the slope should be, is the slope
Now find the slope of the perpendicular line with this formula:
In that case,
Multiply both sides by 10
So the slope of the perpendicular line is -10, or A
Hope this helps!
Answer:
a) Yes
b)No
c) Yes
d) No
Step-by-step explanation:
Remember, a collection of subsets of a set is a partition of if the union of the subsets is , that is, and the elements of are disjoints.
Let
Then
a) and .
Then the collection is a partition of B.
b) and
Since the sets aren't disjoints then they aren't a partition of B.
c)
and
Then the elements of the collection are disjoints.
Therefore, is a partition of B.
d) because . Then the collection isn't a partition of B.
I’m so sorry I would try my best to answer but I can’t :(
