Concept:
First eliminate the t from x=3t and then put it in y=t² and then graph it. As, limit of t is not restricted so t ∈ R(all real numbers)
As it is difficult to make graph here so I have solved it by hand and add all detail regarding it.
Answer:
27 < 5*n +7
n<4
Step-by-step explanation:
Twenty-seven is smaller than five times a number increased by seven
Increase means add
27 < 5*n +7
Subtract 7 from each side
27-7 <5n+7-7
20 < 5n
Divide by 5
20/5 < 5n/5
4 <n
To answer this item, we let x be the distance that Jimmy drove from his origin and back. Given the speeds, the time it takes for him to travel to and fro are,
t1 = x / 46
t2 = x / 52
respectively.
The equation that would best represent the scenario is,
x/46 - x/52 = 0.6
The value of x from the equation is 239.2.
The trip there takes x/46 which is equal to 239.2/46 which is also equal to 5.2 hours. The travel from the cabin back took 4.6 hours.
Answer:
10 units and 2 units is our answer
