Answer:
y = 2x² - 10
Step-by-step explanation:
We must find a pattern in the numbers. Set out the numbers in a table (Columns 1 and 2 in the table).
<u>x</u> <u> y</u> <u>y/2</u> <u>y/2 + 5
</u>
2 -2 -1 4
3 8 4 9
4 22 11 16
5 40 20 25
It looks like all y-values are multiples of 2.
Let's divide them by 2 (Column 3).
The numbers don't increase evenly. We may have a quadratic function.
If we add 5 to each quotient, we get a set of values equal to x² (Column 4).
y/2 + 5 = x²
y + 10 = 2x²
y = 2x² - 10
The function is y = 2x² - 10.

Step-by-step explanation:
The perimeter of rectangle is given by :-
, where l is length and w is width of the rectangle.
Given : Two sides of a rectangle are 4 cm in length. The other two sides are 6 cm in length.
The perimeter of the rectangle will be :_
We know that 1 cm = 10 mm
Therefore, perimeter of the rectangle = 
Answer:
-10; no
Step-by-step explanation:
<h2>
-4*3 + 9*2 + 8*-2 = -10</h2><h2>
</h2><h2>
-10 does not equal 0 so it is not perpendicular</h2>
