xe^-x+7e^-x=0
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.
The resultant of the given equation will be : y = 21
Given,
2/3y+y-4=31
Here,
First add the terms having same variable.
Add 2/3 y and y
2/3 y + y
= 5y/3
Now take -4 from LHS to RHS ,
5y/3 = 35
y = 7* 3
y = 21

At f(-3) the graph is equal to -9.
In order to find the point on the graph, move over to -3 on the x axis. Then move down to find the point where it hits the parabola. You'll see that the parabola hits at point (-3, -9).
