Answer:
Explanation:
The statement is expressed as
y
∝
1
x
inverse means
1
variable
To convert to an equation introduce k, the constant of variation.
y
=
k
×
1
x
⇒
y
=
k
x
To find k use the given condition that y = 8 when x = 4
8
=
k
4
⇒
k
=
4

8
=

Answer: y=-3/4x
Step by step explanation:
y-y_0=m(x-x_0)
y+3=-3/4(x-4)
y=-3/4x+3-3
y=-3/4x
m=rise/run
m=-3/4
6x²-5x-4=0
x=(-b+/√b²-4ac)/2a
D=b²-4ac=25+4*6*4=121, √D=√121=11
x=(5+/-11)/12
x1=-6/12=-1/2
x2=16/12=4/3
