Answer:
y=65
x=50
Step-by-step explanation:
exterior angle of a triamgle is equal to sum of two interior angles
so
2y=130(as it is isosceles triangle)
y=65
we know y+y+x=180(sum of all angles of triangle)and (vertically opposite angle)
therefore, x=50
3n+4=-5
do the opposite of adding 4. this means you have to subtract 4 from 4. whatever you do to the problem, you must do to the answer. now subtract 4 from -5.
-5-4=-9
since 4-4=0, we can take 4 out of the equation. now you have:
3n=-9
now divide -9 by 3
-9/3=-3
n=-3
hope this helps :)
Answer:

The graph has a closed circle.
–7 is part of the solution.
Step-by-step explanation:
Given

Required
Select 3 options from the given list of options

Subtract 22 from both sides


Swap positions of the expression; Note that the inequality sign will change

This means <em>x less-than-or-equal-to negative 7</em>
<em></em>
There are two options left to select;
The inequality sign in
implies that the graph has a close circle.
Inequality signs such as
and
signifies a close circle
There is only one option left to select;
Lastly;
Split the expression
into two
We have:
or 
Because
,
Then, -7 is also a part of the solution
