2. y=x-3
3. y=3x+1
4. y=-3x-3
8.05 x 10^8 - 9.16 x 10^6
= 10^6 (805 - 9.16)
= 795.84 x 10^6
= 7.9584 x 10^8
Use formula a squared equals to c squared minus b squared
40^2-24^2 is 1024
Square root of 1024 is 32.0
The square root would be 3.4 if rounded to the tenths place
X = 1/2 y = 4 by elimination
