I think you meant to say

and not "4 times y" on the right side (which would lead to a complex value for y when x = 0). Note that when x = 0, the equation reduces to ln(y) = 0, so that y = 1.
Implicitly differentiating both sides with respect to x, taking y = y(x), and solving for dy/dx gives


Note that when x = 0 and y = 1, we have dy/dx = 3.
Differentiate both sides again with respect to x :

No need to simplify; just plug in x = 0, y = 1, and dy/dx = 3 to get

B) Find the mean and variance of the number that survive
explanation:
Answer:
-43
Step-by-step explanation:
Follow PEMDAS as well as the left -> right rule.
Note that: PEMDAS =
Parenthesis

Subtraction
First, solve the multiplication:
23 + (5 * 3) - 100 + 19
23 + (15) - 100 + 19
Simplify. Follow the left-> right rule:
(23 + 15) - 100 + 19
38 - 100 + 19
(38 - 100) + 19
-62 + 19 = -43
-43 is your answer.

A=automobile S=SUV
0.4A+A=98 (to change a percent to a decimal you move the decimal point two places to the right)
1.4A=98 (I combined like terms)
A=70 (divided each side by 1.4)
Answer:
C. When there is no gas in the tank, 0 miles can be driven.
