Hello :)
140% of 35 is 25 <span>
x = 25</span>
No. The line just has to go below ' 1 '.
ANSWER
7 units left.
EXPLANATION
The parent function is
The transformation
shifts the graph of the function, a units to the left.
Therefore the transformation that describes how to translate the graph of
y=|x| to obtain y=|x+7| is 7 units left.
The third choice is correct
First of all we can rule out that the slope is 10. The coefficient before the x term is not 10 so the answer is not a.
Following on what I said for option a, option b is correct as the coefficient before the x term is -7/8. Therefore the answer is B.
The answer is not C as when x = 0, y is not 0. This means the line does not pass through the origin (0,0)
Option D is not true aswell. When x = 1, y= 9.125. When x= 2, y= 8.25. When x=3, y= 7.375. X is increasing whereas y is decreasing. Therefore option D is ruled out.
The answer is option B.
I hope this has helped you.
Please mark as brainliest if you are happy with this explanation. Have a great day!
follows from the fact that the cosine function is
-periodic, which means
. Roughly speaking, this is the same as saying that a point on a circle is the same as the point you get by completing a full revolution around the circle (i.e. add
to the original point's angle with respect to the horizontal axis).
If you make another complete revolution (so we're effectively adding
) we get the same result:
. This is true for any number of complete revolutions, so that this pattern holds for any even multiple of
added to the argument. Therefore
for any integer
.
Next, because
, it follows that
is also true for any integer
. So we have
The rest follows from considering either case and solving for
.
