Answer:

Step-by-step explanation:
4x^2+ 12x = 135
D=b²−4ac=122−4(4)(−135)=144+2160=2304=48²

Answer:
y + 1 = 3(x - 5) Answer
Step-by-step explanation:
<u><em>Find the slope of the perpendicular line.</em></u>
m1 * m2 = - 1
m1 = - 1/3
m2 is the slope of the perpendicular
(-1/3) * m2 = - 1 Multiply both sides by -3
-(3)(-1/3) * m2 = -1 * -3
m2 = 3
The slope of the perpendicular line is 3
<em><u>Find the equation of the line.</u></em>
m = (y - y1)/(x -x1)
y - y1 = m(x - x1) is the equation of the line.
y1 =5
x1 = - 1
(y - - 1) = 3(x - 5)
y + 1 = 3(x - 5) Answer

-4.5 rose 9.7 then fell 4.8
-4.5 + 9.7 = 5.2
5.2 - 4.8 = 0.4
