Answer:

One fourth

Step-by-step explanation:

\frac{area \: of \: sector}{area \: of \: circle}  =  \frac{ \frac{ 90 \degree}{360 \degree  } \times \pi {r}^{2}}{ \pi {r}^{2}}  \\  =  \frac{ \frac{1}{4}  \times 1}{1}  \\  =  \frac{1}{4}  \\  = 1 : 4

Answer: B) Infinitely many solutions; both equations are equivalent

==============================================================

Work Shown:

x+y = 4 ... start with the first equation

x + (-x+4) = 4 ... replace y with (-x+4)

x-x+4 = 4

0x+4 = 4

0+4 = 4

4 = 4 ... this is a true statement regardless of what x you pick

So there are infinitely many solutions. Each solution (x,y) is of the form (x,-x+4). All solutions fall on the line y = -x+4 which is equivalent to x+y = 4. Note how we add x to both sides.

Or you could start with x+y = 4 and subtract x from both sides to get y = -x+4. Either way, we're dealing with the same equation which is why they both graph out the same line.
