Answer:
I am taking the equations as 3y= -x+8
43y= -x-5
according to this there is only one unique solution
Step-by-step explanation:
se to identify solution identify type of line first
check the ratio of coffecient of variable and constant
if y1/y2 = x1/x2 = c1/c2 then the lines are coinciding and have infinite solution
if y ratio is not equal to x then 1 solution as I your question
Answer:
it is irrational because the square root is a series numbers whereas a rational number can be expressed as a fraction (recurring and terminating decimals) but irrational numbers can't be expressed as a fraction

To calculate hydronium concentration from pH, type on you calculator
10 to the power of negative pH value
10^-5.5 = 3•10^6 mol/L
Since there are 3 hydrogens in every hydronium molecule,
There are 9 • 10^6 hydrogens in that liter of acid.
