How would you model the function rule Y=-2x-3 with a table of values. can you pretty please show your work i just need help i've
been on this problem for like 20 mins
1 answer:
Y = -2x - 3
First make a table, then start inserting the x's you choose and figure out the y's.
x y
----------------------
-2 -2(-2) -3
4 - 3
1
-----------------------
-1 -2(-1) - 3
2 - 3
-1
------------------------
0 -2(0) - 3
0 - 3
-3
-------------------------
1 -2(1) - 3
-2 - 3
-5
--------------------------
2 -2(2) - 3
-4 - 3
-7
--------------------------
Now you can plot the points into a graph.
(-2, 1), (-1, -1), (0, -3), (1, -5), (2, -7)

Answer:
The money of Greg after five years is $80
The money of Sabrena after five years is $160,000
So,The money of Sabrena is more than Greg after five years .
Step-by-step explanation:
Given as :
Greg invested $20 and quadrupled his money in five years
Let the quadrupled money after five years = $x
∵ quadrupled means the money becomes 4 times of previous
So, x = $20 × 4
i.e x = $80
So, The money of Greg after five years is $80
Again
Sabrena invested $20 and after five years money becomes 20 to the fourth power
Let the money after 20 to the fourth power = $y
So, y =
i.e y = 160,000
So, The money of Sabrena after five years is $160,000
∵ Sabrena money is more than Greg money
Hence, The money of Sabrena is more after five years . Answer
