Answer:
Answer for A
Step-by-step explanation:
I don't know about B , Sorry for that.
3x - 2y = 1
2x + 2y = 4
Add the second equation to the first
5x = 5
2x + 2y = 4
Divide the first equation by 5
x = 1
2x + 2y = 4
Subtract the first equation from the second
x = 1
x + 2y = 3
Subtract the first equation from the second again
x = 1
2y = 2
Divide the second equation by 2
x = 1
y = 1
<h3>
So, the solution is x = 1 and y = 1 {or: (1, 1)} </h3>
I don’t see the problems you want me to solve. Sorry
The answer is y=3(x-1)^2+6
To get percent error you take actual-predicted and divide by the actual then multiply by 100 to get the percent.
65-50=15
15/60=0.25
0.25 times 100 =25%
