Answer:
The y-intercept represents the initial money that Jana has in his account.
Step-by-step explanation:
Given the equation of line is 
.
Also, Jana earns $
per week.
And 
is the number of weeks she has been working.
If we plug week 
in the equation . It will give us the y-intercept.
That means the amount of money in Jana's account before she began mowing lawns.
The y-intercept represents the initial money that Jana has in his account.

Rounded Total: $22
Exact Total: $21.77
B) The total on the register is reasonable because even with the rounded price at the end, it is only 23 cents off, which is good.
Answer:
1.14 products per hour of labor
Step-by-step explanation:
To calculate the daily productivity would be the amount of products per hour of labor.
That is: 400 products / 350 hours of labor, and that is approximately 1.14 products per hour of labor.
Which means that for every hour of labor, 1.14 products are produced in one day, which would be a factor of productivity.
Answer: Sample Response :Use the linear combination method.
Multiply the first equation by –2 to create opposite terms for x.
Multiply the first equation by –4 to create opposite terms for y.
Add the system of equations to eliminate a variable.
Step-by-step explanation:
The correct question is
<span>Rui is a professional deep water free diver. His altitude (in meters relative to sea level), xxx seconds after diving, is modeled by: d(x)=1/2x^2 -10x What is the lowest altitude Rui will reach?
we have that
</span>d(x)=(1/2)x² -10x
we know that
the function is quadratic (a parabola)
so
<span>the lowest altitude (depth) is the vertex
</span>
using a graph tool
see the attached figure
the vertex is the point (10,-50)
that means
His altitude (in meters relative to sea level), 10 seconds after diving is 50 meters under the sea level
therefore
the answer is<span>
the lowest altitude is 50 meters under the sea level</span>
