Here, we are missing the slope and the y intercept. 

Lets look for the y intercept first. 

Where does it cross the y axis?  At 3!!

3 is the y intercept. 

Now, find the slope by using the slope formula. 

m =  \frac{y2 - y1}{x2 - x1}
(0,3) and (2,1)

m = 1-3/2-0 = -2/2 = -2/2 = -1
m = -1

Okay, so we found our slope, now just write the equation. 

Answer: y = -1x + 3

(1 point) A chain 64 meters long whose mass is 24 kilograms is hanging over the edge of a tall building and does not touch the g
miss Akunina [59]

Answer:

W = 2747,1 [J]

Step-by-step explanation:

Chain is 64 meters long with mass 24 Kg

Then weight of the chain is p = 24 * 9.8

p = 235.2 [N]         N = kg*m/s²

And by meter is 235,2 / 64    = 3.675

Total work has two component

- work to lift the 13 top meters of chain  W₁

W₁ = ∫₀ᵇ F(y) dy

- work to lift last ( 64 - 13 ) meters  51   W₂

W₂ = 3.675 * 51 * 13      Kg m² /s²   [J]

W₂ =  2436,53 [J]

We need to calculate  W₁

W₁  = ∫¹³₀ mgy dy    ⇒     W₁  = ∫¹³₀ 3,675 ydy

W₁  = 3,675* ∫¹³₀ ydy     W₁  = 3,675* y²/2  |₀¹³

W₁  = 3,675* 84,5 [J]

W₁  = 310,54 [J]

And total work W

W = W₁ + W₂

W = 310,54  + 2436,53 [J]

W = 2747,1 [J]

Find the difference quotient and simplify your answer. f(x) = 7x − x2, f(7 + h) − f(7) h , h ≠ 0
uranmaximum [27]
Whatever is inside of the ( ), simply plug that digit into the x-values for f(x)
So: f(x) = 7x - x^2, and f(7+h) - f(7)
= [7(7+h) - (7+h)^2] - [7(7) - (7)^2]
= [49+7h - 49+14h+h^2] - [49-49]
= 49-49 + 7h+14h + h^2 = h^2 + 21h =
h (h+21), h (h+21) = 0
h=0... But it stated h cannot = 0
So h+21 = 0, h = -21
