Answer:60.2857143
Step-by-step explanation:
X+2y
Plug in the variables
4+2(7)
4+14
x+2y=18
65x^2 + 212x - 133
you have to use the quadratic formula
x=( -b +/- √b²-4ac) / 2a
a is 65
b is 212
c is 133
because the first value is squared you will have 2 answers
x= 7/13
x= - 19/5
Answer: g(x) -1/2fx-1
Step-by-step explanation: Pretty much you distribute the 1/2f to the x and the 2 then you got you function.
