Answer:
(5.33 + 2h) ≥ 7
h ≥ 0.835
Step-by-step explanation:
Let in the last two days Julian has to practice the drum for h hours each.
Then in two days, he has to practice 2h hours,
He has already practiced 
hours before those last two days.
Therefore, he has practiced this week by (5.33 + 2h) hours.
Now, given that Julian needs to spend at least 7 hours each week practicing the drums.
Hence, we can write the inequality
(5.33 + 2h) ≥ 7
⇒ 2h ≥ 1.67
⇒ h ≥ 0.835 hours
Therefore, Julian has to practice for 0.835 hours for the last two days of the week. (Answer)
Answer:
The answer is 40 sq. units
That is: 1/2×b×h (formula for area of triangle)
1/2×10×8
= 40
Answer:
The equation not represent a proportional relationship because the line don't passes through the origin
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>
so
In this problem we have
This is the equation of the line in slope intercept form
where
the slope is m=5
the y-intercept is b=5
Remember that in a proportional relationship the value of b must be equal to zero (because the line passes through the origin)
therefore
The equation not represent a proportional relationship because the line don't passes through the origin
If I am understanding this right, since the <em>c </em>is a variable, you'd have to solve the equation and have the variable in the and result.
the sqrt525^7 = 3359983566.19
So you'd have to simplify this and add the <em>c</em> to the end of it. Unless your work is fractions.
(I take Algebra II I should be more confident on this topic, this is just what makes the most sense)
