Answer:
25. (12/6)^2 = 4
27. x = 15
28. x = 7
29. x = 6
36. x = 13
37. x = 2
38. x = 4
Step-by-step explanation:
Answer:
To answer your question: Rewrite 81x2 as (9x)2.(9x)2−49Rewrite 49 as 72.(9x)2−72 Both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) where a=9x and b=7.(9x+7)(9x−7)
Answer:
C) 4tan34
Step-by-step explanation:
TOA
tan(x) = Opposite/Adjacent
Opposite the angle, adjacent meaning next to the angle
sub in values
tan(34) = x/4
multiply each side by 4
x = 4tan(34)
There's your answer.
A true function can only have one specific y-value for each x-value.
Therefore, something like this would NOT be a function:
(2,3), (2,0) there are two y-values for the same x-value (not a function)
However, this example WOULD be a function:
(2,3), (4,4), (5,2), (3,2)
it is still a function even if there are two of the same y-values for two different x-values. There just can't be two same x-values with different y-values.
Hope that helps!
