Solve the equation for t. (t-7)^2+18=9

Anika [276]

Answer:

t = 7 + 3i

Step-by-step explanation:

(t-7)^2 + 18 = 9

(t-7)^2 = 9 - 18

(t-7)^2 = -9

(t-7) = sqrt(-9) = |3| sqrt(-1)

t = 7 + 3i

PLZ HELP THANKS! Find the equation of the line passing through the pair points (-8,6) (-9,-9). The equation of the line in the f

timurjin [86]

Answer:

The answer is

Step-by-step explanation:

To find the equation of the line we must first find the slope (m)

$m = \frac{y2 - y1 }{x2 - x1}$

So the slope of the line using points

(-8,6) (-9,-9) is

$m = \frac{ - 9 - 6}{ - 9 + 8} = \frac{ - 15}{ - 1} = 15$

So the equation of the line using point (-8,6) and slope 15 is

y - 6 = 15( x + 8)

y - 6 = 15x + 120

Writing the equation in the form

Ax+By=C

We have

15x - y = -120-6

The final answer is

Hope this helps you
