7ab a - b
-------------- - --------------
a^2 - b^2 a + b
7ab a - b
= -------------- - --------------
(a-b)(a+b) a + b
7ab (a - b)^2
= -------------- - -----------------------
(a-b)(a+b) (a + b)(a-b)
7ab a^2 - 2ab + b^2

(a-b)(a+b) (a + b)(a-b)
7ab - a^2 + 2ab - b^2

= -----------------------------------
(a-b)(a+b)
Answer is A. first one
4, 2, 1, 3
we cannot use 2 before having another triangle, so 4 must be before 2
we can use 1, but it will be just a restatement of the given information is not done before 4 and 2
3 is the final goal, which is always the last step
Answer:
x ≤ 1
Step-by-step explanation:
8 + 4x 
12
4x 12 - 8
4x ≥ 4
Dividing both sides by 4 gives;
x ≤ 1
Answer:
Step-by-step explanation:
Since f(x) and g(x) share the same top at (0,0), their difference is only a scale factor, so g(x) = ax² but we need to find a.
To find it, we use the given point of g, (2,1)
So g(2) = 1
meaning that
a·2² = 1
4a = 1
a = 1/4
Answer:
Option A
Step-by-step explanation:
Sin(x) is the same value as cos(y) in the graph.
