Step-by-step explanation:
gradient = slope or several other words.
it describes how strongly a line (or tangent to a bent curve) is going up or down or ... if it is changing at all.
it is represented by the ratio
(y coordinate change / x coordinate change)
when going from one point on the line to another.
in our case, when going from A to B we have
x changes by -2k (from 3k to k).
y changes by -11 (from 8 to -3).
so, the gradient or slope is
-11/-2k = 3
11/2k = 3
11 = 3×2k = 6k
k = 11/6
A = (33/6, 8) = (11/2, 8)
B = (11/6, -3)
Answer: If the x2-9 is x^2-9, then this is the answer. If not and it's supposed to be 2x then the answer is x=2 or x=−7 or x=9/2
Step-by-step explanation:
3(x−2)(x2−9)(x+7)=0
3x4+15x3−69x2−135x+378=0
Step 1: Factor left side of equation.
3(x−2)(x+3)(x−3)(x+7)=0
Step 2: Set factors equal to 0.
x−2=0 or x+3=0 or x−3=0 or x+7=0
x=2 or x=−3 or x=3 or x=−7
