Answer:
it depends on the shelf
Step-by-step explanation:
Answer:
if you pit the shape in a straight line it would be 180 degrees now take 180 take 130 and 100 and subtract those add that to the other 30 then take 180 divided by 60
Answer:
because it has a weak inter molecular forces between its layers
The given equation is: 
To find the line perpendicular to it, we interchange coefficients and switch the signs of one coefficient.
The equation to a line perpendicular to it is:
$ 2y-x=c$
where, $c$ is some constant we have determine using the condition given.
It passes through $(2,-1)$
Put the point in our equation:
$2(-1)-(2)=c$
$c=-2-2$
$c=-4$
The final equation is:
$\boxed{ 2y-x=-4}$
Answer:
There is only one solution and the solution is (0,4).
Step-by-step explanation:
The given system has equations;

and

We equate the two equations to determine their point of intersection;




We put x=0 into the first equation to get;

There is only one solution and the solution is (0,4).
