Answer:
x= -15
Step-by-step explanation:
3x+10=2x-5
3(-15)+10=2(-15)-5
-45+10=-30-5
-35=-35
Each side of the angle is equal, that's how i knew the two were supposed to be equal. <3 Hope this helps!

(a) both a relation and a function
<u>Step-by-step explanation:</u>
In math, the relation is between the x-values and y-values of ordered pairs. The set of all x-values is called the domain, and the set of all y-values is called the range. We must have a value of y for a value of x and so it's a relation.
Here , y = x/3 for every value of x we have a value of y as at x=1 we have y=1/3. So, it is a relation. Now, Relation is function when it passes vertical line test i.e. when we draw graph of y if we sketch many distinct vertical lines they all must cut graph at only one point and so its function. Basically, for every value of x we must have only one value of y. Y = x/3 follows the above rule and so its also a function! ∴ y=x/3 is both a relation & a function.
Answer:
is irrational
Step-by-step explanation:
Let us assume that is rational. Thus, it can be expressed in the form of fraction 
, where x and y are co-prime to each other.
=
Squaring both sides,
Now, it is clear that x is an even number. So, let us substitute x = 2u
Thus,
Thus, 
is even, which follows the fact that y is also an even number. But this is a contradiction as x and y have a common factor that is 2 but we assumed that the fraction was in lowest form.
Hence, is not a rational number. But is a an irrational number.
Amount of water that the bucket can hold = 2 3/4 gallons
= 11/4 gallons
Amount of water that is present in the bucket = (5/8) * (11/4) gallons
= 55/32 gallons
= 1 23/32 gallons
So the amount of water contained in the bucket is 1 23/32 gallons.
Cos b, I think this should help...
