We know that
<span>Keisha’s reasoning
</span><span>to create the sequence we are going to need the first two terms, so if we only have the first term, we can not calculate the sequence

Personal conjecture
let
a1=2
a2=4
a3=8
a4=?
a2/a1=4/2------> 2--------> a2=a1*2
a3/a2=8/4------> 4--------> a3=a2=2
so
this is a geometric sequence with a common ratio of 2
a4=2*a3-------> a4=2*8------> a4=16
Answer:
x = -1
y = 1
Step-by-step explanation:
y = 3x+4
y = -2x-1
-2x-1 = 3x+4
-5x - 1 = 4
-5x = 5
x = -1
Substitute this x value into 1 of the equations given in the problem:
y = 3(-1)+4
y = -3+4
y = 1
Answer:
1mm = 0.04in;
56mm = 0.04x56in = 2.24in;
Step-by-step explanation:
Answer:
-4
Step-by-step explanation:
-1.5 (4-r) = -12 Distribute the -1.5.
-6 - 1.5r = -12 Add 6 to both sides.
-1.5r = 6 Divide both sides by -1.5.
r = -4
