Y=4 is the answer for this
We can first look into the properties of parallelogram,you can also take reference from the figure above:
-Opposite sides are parallel and are congruent.
-Opposite angles are congruent.
-The diagonals bisect each other.
We can then look into the answer:
A.Opposite angles are congurent.
-This is an correct statement.
B.Diagonals are congruent.
-This is incorrect,although they bisect each other,they do not have the same length.
C.The diagonals are peroendicular to each other.
-This is incorrect as well,not every parallelogram has the angle of 90° in the place where the diagonals bisect each others.
D.The area is equal to the product of two adjacent side-this is not true,to find the area,it have to be base×height.
Therefore the answer is A.
Hope it helps!
S = 32200 + 700y
S stands for salary and y stands for year
Answer:
1 and 2 is and 3 is not
Step-by-step explanation:
<span>The line goes through the points (4,-3) and (0,-2), so its gradient is (-2-(-3))/(0-4) = -1/4. The y-intercept is -2 because f(0)=-2. So the equation of the line is y = -1/4 x - 2.This can be represented by the linear function f(x) = (-1/4)x - 2.
The composite function ff is given by ff(x) = f(-1/4 x - 2) = (-1/4)((-1/4)x - 2) - 2 = x/16 - 3/2.</span>
