There are 100 squares in the grid.
63 are shaded.
Number of squares shaded is the numerator (number on top of the decimal).
Total number of squares is the denominator (number at the bottom of the decimal).
Whenever the denominator of the fraction is 100, you can just take the numerator and put a decimal behind the number.
Therefore, the decimal represented would be 0.63.
Answer:
Y = 4/5x + 0
Step-by-step explanation:
y - 4 = 4/5(x-5)
y-4=4/5x-4
y=4/5x-4+4

A graphing calculator can show you a graph of each expression, which you can compare to the offered choices.
_____
You can make use of the relations ...
... sin(a)+sin(b) = 2sin((a+b)/2)cos((a-b)/2)
... cos(a)+cos(b) = 2cos((a+b)/2)cos((a-b)/2)
... cos(a)-cos(b) = -2sin((a+b)/2)sin((a-b)/2)
Then you have ...
and ...
