Answer:
you are correct! nonlinear
Step-by-step explanation:
when this equation is graphed it forms a curved line-- making it non linear :)
No, you can't. If the denominator is greater than the numerator, that fraction's absolute value is always less than 1. If the numerator is greater than the denominator, that fraction's absolute value is always more than 1. Therefore, for both of them to be equal to each other, you are saying that a fraction that is less than 1 is equal to the fraction more than one. However, you can have a fraction with a larger denominator actually be of greater value than the one with the larger numerator. For example, -(9/8) vs -(8/9). -(9/8) has a greater numerator, yet -(8/9) is greater than it, despite having a larger denominator. Of course, this case can be written off as having the negative factored in with either the numerator with denominator, so it is easier to remember the rule above without the negative mumbo jumbo.
Answer:
Answer is (1): 2 times (x^2 -13)
Step-by-step explanation:
Using the FOIL method, you can conclude that (x-5)(x+5) is X^2 -5x +5x -25. Since the two middle terms cancel, you are left with X^2 -25. For the right side of the equation, (x-1)(x+1), using the FOIL method gets you x^2 -x +x -1. Once again, the -x and x cancel out and you end up with X^2 -1. To add both of these together, you can get rid of all parentheses and do the work. Two x^2 added together is 2X^2, and -25-1 is negative 26. After this, you end up with 2x^2 -26. To get to your final answer you need to take out the GCF of both terms, (the largest number that can go into 2x^2 and -26), which is 2. Taking the two out leaves us with 2(x^2 -13), which is your final answer. It looks like you were on the right track.
FOIL Property
Multiply first terms
Then Outside terms
Then inside terms
Then the last terms
