if dy/dx = x(y-1), find the equation of the tangent line at x=-2 with f(-2)=3
Answer:
The equation of the tangent line passing through the point (-2,3) is
4 x + y +5 =0
Step-by-step explanation:
Step(i):-
Given that the slope of the tangent
[tex]m = \frac{dy}{dx} = x(y-1)[/tex]
m = -2( 3-1) = -4
Given point x = -2
y = f(-2) =3
∴The given point ( x₁ , y₁) = ( -2 ,3)
Step(ii):-
The equation of the tangent line passing through the point (-2,3)
[tex]y - y_{1} = m(x-x_{1} )[/tex]
[tex]y -3 = -4(x-(-2))[/tex]
y -3 = -4( x+2)
y-3 = -4x -8
4x + y -3+8=0
4x +y +5=0
Step(iii):-
The equation of the tangent line passing through the point (-2,3) is
4 x + y +5 =0

Answer:
1- a
2- b
3- c
4- d
Step-by-step explanation:
For any operation you have to separate the numbers from the unknown quantities (x, y) and then simplify them by solving them with quantities you are familiar with.
Example:
7x + 8 - 6 + 3x
7x + 3x + 8 - 6
you can only solve operations if they are both natural or algebraic numbers
10x + 2

A new car is purchased for $40,000 and over time its value depreciates by one half every 3 years. What is the value of the car 17 years after it was purchased, to the nearest hundred dollars?
Answer:
Value of the car after depreciation = $800.
Step-by-step explanation:
Formula to get the final value of the car after depreciation of the car price,
Final value = [tex]\text{Initial value}(1-\frac{r}{100})^{\frac{t}{n} }[/tex]
Here, t = Number of years after the purchase
n = Number of years for the depreciation of price by half
By substituting values in the formula,
Final value = [tex]40000(1-\frac{50}{100})^{\frac{17}{3}}[/tex]
= [tex]40000(0.5)^{\frac{17}{3}}[/tex]
= $787.451
≈ $800 [Nearest hundred dollars]
Therefore, after 17 years value of the new car will be $800.

x+3y=10 what is the slope of the line
Answer:
-1/3 is the slope of the line
Step-by-step explanation:
Answer:
[tex]-\frac{1}{3}[/tex]
Step-by-step explanation:
y = mx + b
m is the slope and b is the y-intercept.
Subtract x from both sides of the equation.
x - x + 3y = 10 - x
3y = 10 - x
Divide each term by 3.
[tex]\frac{3y}3y} = \frac{10}{3} + \frac{-x}{3}[/tex]
[tex]y = \frac{-x}{3} + \frac{10}{3}[/tex]
Rewrite in slope intercept form.
[tex]y = -\frac{1}{3}x + \frac{10}{3}[/tex]

Solve for x. 3x−4≤5 Drag and drop a symbol and number into the boxes to correctly complete the inequality.
Answer:
x≤3
Step-by-step explanation:
3x≤5+4
3x≤9
x≤3
x≤3 is the solution of the inequality 3x−4≤5
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
The given inequality is 3x−4≤5
Three times of x minus four lesser than or equal to five.
We have to solve for x
Add 4 on both sides of the inequality
3x≤5+4
3x≤9
Divide both sides by 3
x≤3
Hence, x≤3 is the solution of the inequality 3x−4≤5
