What is the equation of the line with the given slope 7 y-intercept -8?
From the given information the straight line equation is: y = 7x-8
How can you determine the y- intercept if its not given directly?
The y-intercept (or y-intercepts) of an equation is where x = 0. Replace x with zero in the equation, and solve for y.The answer depends on what information you are given - and in what form. If the equation of the curve is given in polar coordinates or in parametric form, the process is quite different to that required when given the Cartesian equation.
How do you find the length and width of a rectangle when given the area and perimeter?
By forming a quadratic equation from the information given and then the length and width can be found by solving the equation.
Does the equation 2y5x 1 represent a direct variation?
Without an equality sign the information given does not represent an equation.
Can you solve this equation 3x 96x solve for x?
Without an equality sign the information given does not qualify it to be an equation
What important information does a thermochemical equation have that a regular balanced equation does not?
A thermochemical equation shows the amount of heat given out or taken in when the reaction occurs. CH4 + 2O2 = CO2 +2H2O, deltaH = -890 kJ/mol Note delta H is negative when heat is given out, exothermic and +ve when endothermic. Sorry can't do delta symbol - its a triangle!

What is the difference between a thermochemical equation and a traditional chemical equation?
Thermochemical equation includes enthalpy ( ΔH ) change in it.
The change in energy represented by a thermochemical equation is always?
The change in energy represented by a thermochemical equation is directly proportional to the number of moles in substances undergoing a change.
How is thermochemical equation different from a balanced chemical equation?
They specify heat flow for the reaction.
What is the thermochemical equation for endothermic changes?
A + B + Heat → C, ΔH > 0
What is the thermochemical equation for the formation of 1.00 mol of liquid water?
H2 + 1/2o2 --> h2o
What type of reaction is shown in this thermochemical equation A plus B plus Heat -- C plus D?
endothermic

What is the balanced thermochemical equation for SO2?
1/8 S8 + O2 --> SO2 , delta H degree f = -296.9 kJ
How do you find the length and width of a rectangle when given the area and perimeter?
By forming a quadratic equation from the information given and then the length and width can be found by solving the equation.
