This is a system of equations. There are three ways you can solve these types of problems, graphing, substitution, or elimination. I'll use eliminations for this one. Elimination means that you try to eliminate one of the variables.
First, I multiply the second equation by 1.25:
1.25x + 2.25y = 916
1.25x + 1.25y = 700
Now, subtract the two equations:
1y = 216
y = 216
Substitute 216 into y of one of the equations:
1.25x + 2.25(216) = 916
1.25x + 486 = 916
1.25x = 430
x = 344
The answer is (344, 216).
Check your answer by substituting these values into the equations:
complete factorization y^4-25y^2+144 (^) denotes following number is Power y^4 - 25y^2 + 144 You might try replacing y^2 with x. Therefore your statement becomes: x^2 - 25x + 144 ...which is easier to factor.
How would you exactly start the first problem? My thermodynamic skills is a bit rusty. I am assuming I have to use ΔH°f under the given reaction..? But then..we barely covered ΔG° in class. Am I to use this equation,
I am solving for sytems of equations using the elimination method. Book says answers are 0,-1. I have tried solving for both x & y using both the 5 and 25 . I am not getting the 0,1 as my answer. 5x-5y=5 25x-25y=22
I need to turn this story into an algebra problem: Your cousin ears $25 per week babysitting and receives one $5 bonus. You earn $15 per week mowing lawns and $12 a week running errands. After working the same number of weeks, you
4) The graph of y = (x)/(1+25x^2) for x is greater than or equal to 0 has a horizontal tangent at x = what. So what I did was find the first derivative. I did the quotient rule and ended up with x50x - 1+25x^2 ---------------
Suppose the ΔGof, ΔHof, and ΔSo are available and valid at 298 K. Which equation(s) could be used to calculate the change in Gibbs Energy if all product and reactant concentrations (pressures) are 1 M (1 atm) and
