Step-by-step explanation:
area of the rectangle = 3×4 cm²
= 12cm²
area of the circle = πr²= π = 3.14
area of the shaded region = 12-3.14 = 8.86 cm²
First write the equations in the slope-intercept form:
![y=mx+b \\ \\ m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=y%3Dmx%2Bb%20%5C%5C%20%5C%5C%0Am%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Line 1 passes through the points (-6,-6) and (-4,-3).
![m=\frac{-3-(-6)}{-4-(-6)}=\frac{-3+6}{-4+6}=\frac{3}{2} \\ \\ (-6,-6) \to x=-6, \ y=-6 \\ -6=\frac{3}{2} \times (-6) + b \\ -6=-9+b \\ b=3 \\ \\ y=\frac{3}{2}x+3](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-3-%28-6%29%7D%7B-4-%28-6%29%7D%3D%5Cfrac%7B-3%2B6%7D%7B-4%2B6%7D%3D%5Cfrac%7B3%7D%7B2%7D%20%5C%5C%20%5C%5C%0A%28-6%2C-6%29%20%5Cto%20x%3D-6%2C%20%5C%20y%3D-6%20%5C%5C%0A-6%3D%5Cfrac%7B3%7D%7B2%7D%20%5Ctimes%20%28-6%29%20%2B%20b%20%5C%5C%0A-6%3D-9%2Bb%20%5C%5C%0Ab%3D3%20%5C%5C%20%5C%5C%20y%3D%5Cfrac%7B3%7D%7B2%7Dx%2B3)
Line 2 passes through the points (0,3) and (2,6).
![m=\frac{6-3}{2-0}=\frac{3}{2} \\ \\ (0,3) \to x=0, \ y=3 \\ 3=\frac{3}{2} \times 0 + b \\ b=3 \\ \\ y=\frac{3}{2}x+3](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B6-3%7D%7B2-0%7D%3D%5Cfrac%7B3%7D%7B2%7D%20%5C%5C%20%5C%5C%0A%280%2C3%29%20%5Cto%20x%3D0%2C%20%5C%20y%3D3%20%5C%5C%0A3%3D%5Cfrac%7B3%7D%7B2%7D%20%5Ctimes%200%20%2B%20b%20%5C%5C%0Ab%3D3%20%5C%5C%20%5C%5C%0Ay%3D%5Cfrac%7B3%7D%7B2%7Dx%2B3)
These are two identical lines so the system of equations has infinitely many solutions. The answer is D.
You multiply by -2 every time.
