NEED HELP ASAP!! <br><br> Use the function below to find F(3)
kvv77 [185]
It’s gonna be 1/125.

Since it’s F(3), you need to plug the 3 into the x. Then expand it into 1/5 times 1/5 times 1/5, which gets you 1/125

Write an equation for the line perpendicular to 2x−3y = 5 and containing (−2, 1).
Nostrana [21]

 

Hello:<span>
the equation is : y = ax+b
the slope is a : a×(2/3) = -1......( perpendicular to a line : 2x-3y =7 with a slope of 2/3 because : y = (2/3)x-7/3)
a = -3/2         y=(-3/2)x+b
the line that passes through (-2, 1) : 1 = (-3/2)(-2)+b
b = -2
<span> the equation is :  y  = (-3/2)x-2</span></span>
