Evaluate the limit as x goes to infinity of the product of x cubed and e raised to the power of negative x over 5

0

Step-by-step explanation:

Rewrite the limit, and you can see that the denominator ends up having a variable as its degree. This means that it's much "powerful" that the degree of the numerator (3). Therefore, as you plug in really really big values, you see that it is basically zero.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.
