The answer is that y is equal to -3 and x is equal to 7
2x-y=17
-2(x-y)=10 )
--------------
2x-y=17
-2x+2y=-20
----------------
y=-3
x-y=10
x-(-3)=10
x+3=10
-3 -3
----------
x=7
Answer:
y = 2x - 12
Step-by-step explanation:
To find the inverse of a function, you switch x and y and solve for y.
x = 1/2 y + 6 switch x and y
x - 6 = 1/2 y subtract 6 from both sides
2x - 12 = y multiply both sides by 2
3 x^{2} - 15x - 42
(x-7)(x+2)
x-7=0 x+2=0
x=7,-2
I think the answer would be C. based on the cost of the treatment alone, plan A should be selected over plan B
If we count the cost and probability of remission, the cost of per 1 % remission with plan A is $ 25 , while the cost of per 1 % remission with plan B is $ 34
hope this helps
