Answer:
graph b because its a parabola
Step-by-step explanation:
Answer:
An explicit rule for the nth term of the sequence will be:
Thus, option (A) is true.
Step-by-step explanation:
Given the sequence

A geometric sequence has a constant ratio r and is defined by

Computing the ratios of all the adjacent terms

As the ratio 'r' is the same.
so

as

Hence, the nth term of the sequence will be:

substituting the values
and 
Therefore, an explicit rule for the nth term of the sequence will be:
Thus, option (A) is true.
Answer:
x=3, y=-1
Step-by-step explanation:

Double the first equation, then add the second
6x+2y=16
+ 2x-2y=8
The y's cancel each other out.
8x=24
x=3
Solve for y
6-2y=8
2y=-2
y=-1
Double check:
6(3)+2(-1)=16
18-2=16
Yay!
Answer:
Step-by-step explanation:
3/4 inch to 1 mile = 1 3/4(or 7/4 in) to x miles
make a proportion
(3/4) (7/4)
-------- = ------- cross multiply
1 x
(3/4)(x) = (7/4)(1)
3/4x = 7/4
x = (7/4) / (3/4)
x = 7/4 * 4/3
x = 7/3 or 2 1/3 miles <===
I'm no sure sorry but try adding them together then if it doesn't work then i'm sorry
