I think that when you asked this question, no one answered because there is not enough information. I also got this problem and there is in fact, a table and a graph.
Step-by-step explanation:
for Hector, it only shows a y and x graph and for Geri it shows a table. let´s call the graph the ¨h¨ graph (for Hector) and the table is going to be called the ¨g¨ graph (for Geri)
on the h graph, it shows that y/x = dollars/time for Hector,
on the g table, it shows that Geri is getting paid $25.50 for each 3 hours and it keeps increasing within each input and output.
your y = your dollars
your x = your time
we are looking for slope and we need $15 over hours
15/x
the answer is that Hector earns $6.50 more than Geri

Answer:
Hence, Grasshopper will land on the ground after 1.5 sec.
Step-by-step explanation:
It s given that:
The height, in feet, of the grasshopper above the ground after t seconds is modeled by the function:
Now we are asked to find:
In how many seconds will the grasshopper land on the ground?
i.e. we have to find the value of t such that h(t)=0
i.e.
i.e. we need to find the roots of the given quadratic equation.
On solving the quadratic equation or plotting it's graph we could observe that the point where h(t)=0 are:
As time can't be negative hence we will consider:
Hence, grasshopper will land on the ground after 1.5 sec.
Total number of $1 bills=7
Total number of $5 bills=8
Further explanation:
Given
Let x be the number of $1 bills
and
y be the number of $5 bills
Then according to the given statements
x+y=15
x+5y=47
From first equation:
Putting x=15-y in second equation
Putting y=8 in first equation
Hence,
Total number of $1 bills=7
Total number of $5 bills=8
