Answer:
Step-by-step explanation:
2) a(a + b) + b(a - b) - 2ab / a² - b²
= a² + ab + ab - b² - 2ab / a² - b²
= a² - b² / a² - b²
= 1
3) [x - 1/(x - 1)(x - 2)] + [x - 2/(x -2)(x - 3)]
= (1 / x - 2) + (1 / x - 3)
= x - 3 + x - 2 / (x - 2)(x - 3)
= 2x - 5 / x² - 5x + 6
Answer:
D. √2 : 1
Step-by-step explanation:
The hypotenuse = 4√2 (longest side of a right triangle)
The given side = 4
Ratio of the hypotenuse to the given side = 4√2 : 4
Simplify by dividing both numbers by 4
√2 : 1
Filling in one equation into the other will lead to elimination of one variable, enabling you to solve the other. In this case it is very easy to eliminate variable e right away. So you end up equating the terms of A and B:
4f + 1 = e = 3f+ 5
Forget e and you see it is answer D.
Answer:
Step-by-step explanation:
The parent function denotes the simplest function (free from any horizontal/vertical stretch/compression) that represents a family of functions. In this case the term 1/4 indicates a horizontal stretch and should be removed to find the parent function of . From here we're in simplest form, since or others represent a completely different family of functions and cannot be obtained from horizontal/vertical stretches/compressions.
