A constant because it a number
12x-5y=2
-5y=2-12x
y=-2/5+12/5x
should know the m=12/5
and (2,3) bring them to the line equation:
3=12/5x2+b
6/5+b=3
b=3-6/5
b=9/5
y=12/5x+9/5
Which means the answer is not in the choices.
The figure seems like its a parallelogram.
In a parallelogram :
Opposite sides are equal and
Opposite angles are equal
Hence, The side opposite to 9in. is equal to 9in. and the side opposite to 10in. is equal to 10in.
Area of the figure =b×h
= 8×10
=80in.sq.
I don't because I can't see
Here we are:
Triangle PQR is equilateral, all the angles are 60, this means that triangle PSR is an isosceles triangle. 180-90=90 90/2=45 60-45=15
B=15
Hope this helps :)
