This one is simple since we already have the two x variables.equal. All we have to do is subtract the equations from one another to get the answer.
So i will subtract the left side by the other left side and the right side by the other right side
-8x - 8y -(-8x + 2y) = 0 -(-20)
distribute negative sign
-8x - 8y + 8x - 2y = 0 + 20
do the math
- 10y = 20
Y = -2
plug t into an equation
-8x -8 (-2) = 0
-8x + 16 = 0
-8x = -16
x = 2
answer (2, -2)
Answer:
13.9%
Step-by-step explanation:
Given data
Expected weight = 230 pounds
Actual weight= 262 pounds
Required
The percent error
Error= Actaul- expected/ expected *100
Error= 262-230/230*100
Error=32/230*100
Error=0.139*100
Error=13.9%
Hence the error is 13.9%
