I have a slope of -4 (m=-4), would that be negative four over positive one or would that be negative 4 over negative one?

katrin [286]

If you have a slope of -4 then it would be -4/1 because rise/run. If it were -4/-1 then the slope would be 4.

your gym membership cost $33 per month after an initial membership fee. you paid a total of $228 after 6 months. writer an equat

grin007 [14]

Answer:

what i did was multiply 33*6 and got 198 and then 228-198 to find out that the initial fee was 30 dollars. then multiply 33*9+30 to get a 9-month total cost of $327

Step-by-step explanation:

cost = $33 per month + fee

1. c(m) = 33m + f

33(6) + f = 228

198 + f = 228

f = $30 membership fee

c(m) = 33m + 30

2. at 9 months: 33(9) + 30 = $327

hopefully this helps :)

have a nice day !!

Derive Sinxy = x² + 2xy

bogdanovich [222]

Answer:

$\frac{dy}{dx} = \frac{2x +2 y- ycosxy}{x(cosxy-2)}$

Step-by-step explanation:

Step(i):-

Given

sin xy = x² + 2xy ...(i)

Apply

$\frac{d}{dx} UV = U^{l} V + U V^{l}$

$\frac{d}{dx} x^{n} = nx^{n-1}$

Differentiating equation (i) with respective to 'x', we get

$cosxy \frac{d}{dx} (xy) = 2x + 2( x\frac{dy}{dx} + y(1))$

$cosxy (x\frac{dy}{dx} +y(1)) = 2x + 2( x\frac{dy}{dx} + y(1))$

$cosxy (x\frac{dy}{dx}) + ycosxy = 2x + 2( x\frac{dy}{dx}) +2 y)$

$cosxy (x\frac{dy}{dx}) - 2( x\frac{dy}{dx}) = 2x +2 y- ycosxy$

$(cosxy-2) (x\frac{dy}{dx}) = 2x +2 y- ycosxy$

$\frac{dy}{dx} = \frac{2x +2 y- ycosxy}{x(cosxy-2)}$
