a
i just wanted another opinion
the way i would work it is first move the equation to standard form because i find it easier to work it that way. 2x-3y=-5 -3y=-2x-5 y=2/3x+5/3 an equation perpendicular to this equation would have a slope of -3/2 because perpendicular lines have opposite
first use y2-y1/x2-x1 to find the slope -4-3/2-(-1)=-7/3 then(assuming the equation is parellel)use point slope form y-y=slope(x-x) y-3=-7/3(x-(-1)) y-3=-7/3x-7/3 y=-7/3x+2/3 then to put it in standard form it must be in the Ax+By=C form with no fractions
y-2=3/4(x+9) y-2=3/4x+6.75 y=3/4x+8.75
what if the question doesnt say that the temperature and pressure stay constant. for example..3.0L of a gas has a pressure of 12.0 atm. What is the new pressure if the gas is expanded to 17.0L?....would you assume that the temperature would stay the same
is the other element mercury?
so when you look up the electronegativity values, the lower value is the positive end and the higher value is the negative end?
sorry this question is out of a lab and i didn't think that nobody would understand the change in temperature since they havent done the lab but that does answer my question.
2x-3(4)=16 2x-12=16 2x=28 x=14
