Answer:
x=-7
Step-by-step explanation:
xe^-x+7e^-x=0
factor out the e^-x
e^-x(x+7)=0
e^-x=0, x+7=0
-x=ln(0), x=0-7=-7,
since ln(0) is undefined,
the only solution is -7.
Answer:
The equation of the line that passes through the point (3,-3) and has a slope of 0 will be:

Step-by-step explanation:
The point-slope form of the equation of a line is:

where
-
is the slope of the line and, -
is a point on the line.
As the slope is
, and the point is 
so
Equation of the line will be:

Further simplifying


Therefore, the equation of the line that passes through the point (3,-3) and has a slope of 0 will be:

Answer:
Step-by-step explanation:
(-1 - 5)/(0 + 3)= -6/3 = -2
y - 5 = -2(x + 3)
y - 5 = -2x - 6
y = -2x - 1
Answer:
well I'm sure if this is entirely correct but i would say it would be 12
