I believe this is correct:
13 x^3-78x^2-234x
pleasa vote my answer brainliest. thanks!
True it is possible to built a triangle with 3.3 and 9. Two long we sides would be 9 and the bottom side would be 3
28=(2+x)+x
-2 -2
_________
26=x+x
26=2x
Divide both by 2
13=x
length=15 width=13
Subtract 3x from both sides:
-6y = -3x + 6
divide both sides by -6 to get y by itself:
y = 1/2x - 1
function notation is rewriting y as a function:
f(x) = 1/2x -1
