Answer:
y-intercept:20
slope:5
Step-by-step explanation:
For this case we have:
By definition, one of the properties of the power, known as negative integer power, states that:
can be written as
Thus, 
can be written as 
. So:
Answer:
Power of negative integer exponent:
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).
When using the X method to solve, you can plug in the values given to you in the answers. 8 and 11 multiplied does equal 88 but when added they don't equal to 26 so A is wrong. 4 and 22 do equal 26 but when multiplied, they don't equal to 88 so B is also wrong. 22 and 4 added together equals 26 and multiplied it equals to 88. So C is your answer.
