The complete question is
<span>-2 2/3, -5 1/3, -10 2/3, -21 1/3, -42 2/3, ... Which formula can be used to describe the sequence?
a. f(x + 1) = –2f(x)
b. f(x + 1) = f(x)
c. f(x + 1) = -f(x)
d. f(x + 1) = 2f(x)
case a) </span>f(x + 1) = –2f(x)
for f(x)=-2 2/3
f(x+1)=-2*[-2 2/3]=5 1/3
5 1/3 is not -5 1/3
therefore
this is not the formula
case b) f(x + 1) = f(x)
for f(x)=-2 2/3
f(x+1)=-2 2/3
-2 2/3 is not -5 1/3
therefore
this is not the formula
case c) f(x + 1) = -f(x)
for f(x)=-2 2/3
f(x+1)=2 2/3
2 2/3 is not -5 1/3
therefore
this is not the formula
case d) f(x + 1) =2f(x)
for f(x)=-2 2/3
f(x+1)=2*[-2 2/3]=-5 1/3
for f(x)=-5 1/3
f(x+1)=2*[-5 1/3]=-10 2/3
for f(x)=-10 2/3
f(x+1)=2*[-10 2/3]=-21 1/3
for f(x)=-21 1/3
f(x+1)=2*[-21 1/3]=-42 2/3
therefore
the answer is the option
d. f(x + 1) = 2f(x)
Answer:
y = (1/2)x is proportional; (1/2)
Step-by-step explanation:
1. y= 1/2x Proportional; constant of proportionality is 1/2.
2. y=2x + 7 Not proportional because of the non-zero y-intercept.
3. x= y + 2 Not proportional (same a reason as for #2)
I believe B or C but that’s a straight guess. i would say B just because if you live like outside of town then ur screwed
A division problem is unsolved, so it is an unknown factor until ithe problem is solved.
Answer:
Segment BC = 36 mm or 3.6 cm
Step by Step Explanation:
There are 10 mm in 1 cm
meaning that segment AC is 40 mm long
if AB is 4 mm and it is one part of the two, then we need to subtract that from the total to find out what is left.
40 - 4 = 36
Segment BC = 36 mm or 3.6 cm
