Answer:
70.69
Step-by-step explanation:
46 2/3 divided by 2/3
46.66 divided by 0.66
The anwser is 70.69
If the cook makes twice as much beef then the number of hamburgers would be two times larger which would be 141.39.
Half as much beef would be 70.69 divided by two which is 35.34.
For f(x) to be a function, the value of x should not be repeated. That is no x value can be more then once.
So the required table is

And for g(x) , not to be a function, we have to repeat x value that is

Xy=10
x+y=29
subtract x from both sides for second equation
y=-x-29
subsitute in second equaiton
x(-x-29)=10
-x^2-29x=10
add x^2+29x to both sides
x^2+29x+10=0
quadratic formula
if you have
ax^2+bx+c=0,
x=

so
x^2+29x+10=0
a=1
b=29
c=10
x=
x=
x=

x=

x=

or

those are the 2 numbers
aprox=-28.65 and -0.349
Um i think that the answer is c.12.46
