Answer:
D.
Step-by-step explanation:
A linear parent graph is always a solid, constantly sloped line. A linear equation looks like a line.
Exponents are a straight horizontal line that curves up after a while.
Quadratics are the big U shaped graph.
Absolute values look like a V graph.
Usually exactly 2 centimeters.
45*(600+78) = 45*600+45*78
45*678=27000+3510
30510=30510
Answer:
The value of y is: 7
Step-by-step explanation:
The figure of the rectangle ABCD is attached to the answer.
We are given that Parallelogram ABCD is a rectangle.
AC=6y−1
BD=4y+13
Diagonal BD and AC intersect each other at a point labeled as X.
Also we know that: The two diagonals of a rectangle are equal in length and bisect each other.
i.e. length of AC=BD
Hence 6y-1=4y+13
⇒ 6y-4y=13+1
⇒ 2y=14
⇒ y=7
Hence, AC=6×7-1=42-1=41
BD=4×7+13=41
Hence, the value of y is 7.
Answer:
the answer is DBC=90°
because the midpoint of the perimeter of quadrilateral is B
