Answer:

y = 2e^[2(1 - t)]

Step-by-step explanation:

1/y . dy = -2. dt

ln(y) = -2t + c

ln(2) = -2(1) + c

c = 2 + ln(2)

ln(y) = -2t + ln(2) + 2

ln(y) - ln(2) = 2 - 2t

ln(y/2) = 2 - 2t

y/2 = e^(2 - 2t)

y = 2e^[2(1 - t)]

10. Solve for x akoajssbsbqn
natka813 [3]

Answer:

x = 5

Step-by-step explanation:

10 * 7 = x * 14

10 * 7 = 70

14 * x = 14x

14x = 70

divide each side by 14

14x / 14 = x

70 / 14 = 5

we're left with x = 5

Y=(x-1)^2+2 find the y-intercept
dybincka [34]

Answer:

(0,3)

Step-by-step explanation:

So we have the equation:

y=(x-1)^2+2

Recall what the y-intercept is. The y-intercept is when the graph crosses the y-axis. Therefore, at that point, the x-value is 0. So, to find the y-intercept, substitute 0 for x. Thus:

y=(0-1)^2+2

Subtract:

y=(-1)^2+2

Square:

y=1+2

Add:

y=3

So, the y-intercept is at (0,3).

And we're done!
