Answer:

2 and 3

1 also has a y-intercept of 3, but it is negative, so I don't know if that one will count

Step-by-step explanation:

Substitute X for 0 and solve from there.

3(0) - 2y = -6

0 - 2y = -6

y = 3

y - 3 = -2(0)

y - 3 = 0

y = 3

Can you help me solve for x? 1/3(3x-1)=-1/5-2/5

Deffense [45]

1/3 ( 3x - 1) = -1/5 - 2/5

1/3 (3x - 1) = -3/5

3x - 1 = -3/5 (3)

3x - 1 = -9/5

3x = -9/5 + 1

3x = -9/5 + 5/5

3x = -4/5

x = -4/15

Find the total surface area of this cone

fenix001 [56]

Answer:

S.A. = 1,017.36

Step-by-step explanation:

S.A. = $\pi r^{2} + \pi rl$

12 x 12 x 3.14 = 452.16

3.14 x 12 x 15 = 565.2

565.2 + 452.16 = 1,017.36

"Find the value of the derivative (if it exists) at each indicated extremum. (If an answer does not exist, enter DNE.) f (x) = c

Oliga [24]

$\bf f(x)=cos\left( \frac{\pi x}{2} \right)\implies \cfrac{df}{dx}=\stackrel{chain~rule}{-sin\left( \frac{\pi x}{2} \right)\cdot \frac{\pi }{2}}$

now, what is the value of the derivative at any extrema on the original function? well, by definition, if the original function has an extrema anywhere, the derivative will be the derivative of a horizontal tangent line to it, and by definition it'll be 0.
