Mine was multiple choice and I got c
Step-by-step explanation:
<span>x^2y=xy^2
Differentiate implicitly.
x^2y' + y(2x) = x(2yy') + y^2
x^2y' + 2xy = 2xyy' + y^2
x^2y' - 2xyy' = y^2 - 2xy
y'(x^2 - 2xy) = y^2 - 2xy
y' = (y^2 - 2xy)/(x^2 - 2xy)</span><span />
Answer:2/3
Step-by-step explanation:
So you add 8 plus 2 And keep the denominator the same and then simplify with 5
Answer:
(x - 4)² - 11
Step-by-step explanation:
Given
x² - 8x + 5
Using the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² - 8x
= x² + 2(- 4)x + 16 - 16 + 5
= (x - 4)² - 11
Answer:
$2673
Step-by-step explanation:
Let x represent average cost of car 50 years ago.
We have been given that over the last 50 years, the average cost of a car has increased by a total of 1,094%. The average cost of a car today is $31,918. We are asked to find the average cost 50 years ago.
We can represent our given information in an equation as:
Therefore, the average cost of the car 50 years ago was $2673.
