Answer:
x=8
Step-by-step explanation:
Because you are solving for x, you want to cancel out the y terms. You can do this by multiplying the entire equations by numbers that will make the y terms have equal numbers but opposite signs.
2(2x-5y=1)
5(-3x+2y=-18)
This turns into
4x-10y=2
-15x+10y=-90
The y terms cancel out, and the other terms can be added together.
-11x=-88
x=8
Answer:
The residual of the point 
in the equation 
is 
Step-by-step explanation:
We have been given point where 
.
Now the equation is .
Plugging the value of in the equation of ,
we have to find the predicted value of y and 
.
So y predicted 
.
To find the residual point we have to subtract the actual value from the predicted value.
As actual value of 
along with the points .
Residual point = Actual value - Predicted value.
So the residual for the point is 
.
Answer: 5.14 cu in
Step-by-step explanation:
1/2 (π × d) + d, where d is the diameter of the semi
Perimeter = 1/2 (3.14 x 2) + 2
= 1/2 * 6.28 + 2
= 3.14 + 2
