Answer:

-81t^2 +16

Step-by-step explanation:

(9t-4)(-9t-4)

FOIL

first: -9t*9t = -81t^2

outer : -4*9t = -36t

inner : -4 *-9t = 46t

last = -4*-4 = 16

Add them together

-81t^2 -36t+36t+16

-81t^2 +16

Write an equation of the line that passes through the given point P and

dexar [7]

Answer (assuming it can be in point-slope form):

$y-4 = 3(x+2)$

Step-by-step explanation:

Use the point-slope formula $y-y_1 = m (x-x_1)$ , to write the equation of the line in point-slope form. Substitute x and y values for $m$ , $x_1$ , and $y_1$ in the formula.

Since $m$ represents the slope, substitute 3 for it. Since $x_1$ and $y_1$ represent the x and y values of a point the line intersects, take the x and y values of point P and substitute them into the equation as well. Substitute -2 for $x_1$ and 4 for $y_1$ . This gives the following answer:

$y-4 = 3(x+2)$
