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
Answer:
see attached diagram
Step-by-step explanation:
First, draw the dashed line 50x+150y=1500 (dashed because the inequality is without notion "or equal to"). You can do it finding x and y intercepts.
When x=0, then 150y=1500, y=10.
When y=0, then 50x=1500, x=30.
Connect points (0,10) and (30,0) to get needed dashed line.
Then determine which region (semiplane) you have to choose. Note that origin's coordinates (0,0) do not satisfy the inequality 50x + 150y>1500, because
This means that origin lies outside the needed region, so you have to choose the semiplane that do not contain origin (see attached diagram).
