We can replace the inequality with qual sign:
2x - y = 4
x + y = -1
We can combine both question
3x = 3
x = 1
Since we know x = 1, we can solve for y by plug in in either equation:
x + y = -1
1 + y =-1
y = -2
or
2x - y = 4
2(1) - y = 4
-y = 2
y = -2

So the solution of this system of equation is the coordinate (1, -2)

u can convert that to 9/2
then to get the reciprocal you flip the denominator and numerator
this gives u 2/9

Identifying a constant of variation question<br><br> R= ?
jek_recluse [69]
Pressure and Volume are inversely related as:

P= \frac{R}{V}

We can also write it as:

PV=R

R is the constant of proportionality. Using the first row of given table, we can write:

2(4.155)=R \\  \\ &#10;R=8.31

Thus, the value of R, the universal gas constant is 8.31
