So this easiest way to solve is to use the elimination method. Basically you just add the equations together. This is what you do.
-5x + y = -11
x - y = 7
Add the equations.(This operation gets rid of the y-value)
-4x = -4
Divide.
x = 1
Now plug in 1 into an equation of your choice and find the value of y.
1 - y = 7
Subtract 1 from both sides.
-y = 6
Divide by -1 because you can't have a -y.
y = -6
So the solution is (1, -6).
I hope this helps love! :)
Answer:
4%
25 x FOUR is 100 so 4 is the answer
Answer:
x² - x + c
Step-by-step explanation:
Using the power rule for integration
∫ a
dx = 
∫ 
dx ( divide terms on numerator by 4 )
= ∫ (2x - 1) dx
= 
- x + c
= x² - x + c ( c is the constant of integration )
