Answer:
x=10, y=-1
Step-by-step explanation:
The coefficients of y are opposites, so the y-variable can be eliminated by adding the two equations.
... (x -y) +(2x +y) = (11) +(19)
... 3x = 30 . . . . . simplify
... x = 10 . . . . . . .divide by the coefficient of x
Use either equation to find y. We can use the first one, for example:
... 10 -y = 11
... -1 = y . . . . . add y-11
The solution is (x, y) = (10, -1).
Answer:
y=44
Step-by-step explanation:
-x+y=27
-17+y=-27
27-(-17)=27+17
27+17=44
Answer:
736.05
Step-by-step explanation:699.00 x 5.3%=37.047
699.00 + 37.05 = 736.05
Answer:

Step-by-step explanation:
The given function is

Which can be rewritten also as

We want to find the values of x for which

In order to do that, we just substitute -12 into f(x), and we solve the equation for x:

I think the answer is 35.82 because if you see it is 3 then is adding 4 and it makes 7 and then you have to add 7 plus five is 12 so then the answer is 35.82
