Now before taking the inverse tangent of both sides, recall that
where
is any integer. This means that when taking the inverse tangent of
, instead of just
, we would end up with
So after doing so in the equation above, we're left with
As
can be any integer, including negative integers, we can simply write
The vertical angles made is ABE and CBD, Thus meaning that your answer is B
Answer: (x+5)(x-3)
Explanation:
Write 2x as a difference so (that also =15) so 5x-3x
That end up being x^2+5x-3x-15 now putting into factorisation (x+5)(x-3)
Hope this helps:)
5x + 8y = -29
7x - 2y = -67 ..... multiply both sides by 4
5x + 8y = -29
28x - 8y = -268
33x + 0y = -297
x = -9
(-9, 2)
The square root of some numbers (for example the number 60) is an irrational number that never terminates or repeats (7.745 966 692 ...). Benchmark numbers can be used to state that the square root of 60 is between 6 and 7. The square root of 60, estimated to two decimal places is 7.75.
