42-x=58
or, -x=58-42
with change in side sign also chamges we change sides to make like terms in one side and unlike in amother side.
or, -x= 16
or,x=-16.
therefore x=-16...

Answer:
20 × 9= 180

Answer:
B
Step-by-step explanation:
We can determine that it is sin, not cos, because the equation goes through the origin (0, 0).
The amplitude is 2 and since the amplitude is a for an equation in the form of asinx, the equation must have 2sinx.
Finally, the period is pi. The regular period of sinx is 2pi, so inside of the si, x must be multiplied by 2, which gets us to 2sin(2x).
I hope this helps! :)
Answer:
a.ABCD is reflected over both axes.
Step-by-step explanation:
Reflection over x-axis transforms point (x, y) into (x, -y)
Reflection over y-axis transforms point (x, y) into (-x, y)
Then, reflection over both axes transforms point (x, y) into (-x, -y). Applying this rule to figure ABCD:
A (-2, 2) -> (2, -2) which corresponds to point A'
B (-1, 2) -> (1, -2) which corresponds to point B'
C (-1, 1) -> (1, -1) which corresponds to point C'
D (-3, 1) -> (3, -1) which corresponds to point D'
