Since x and y are directly related, the equation for their comparison will look like
kx = y
where k is your constant. They give you an instance in the problem where x = 27 and y = 81. Plug this into the above equation and solve for k.
kx = y
k (27) = 81
k = 3
Thus, the constant of variation is 3.
Answer:
See the graph of the given inequality in the attachment as shown below:
Step-by-step explanation:
Given the inequality: 
To graph this inequality on the number line.
Remember:
- If the symbol is
then you fill in the dot
- If the symbol is
then you do not fill in the dot.
Since, in the given inequality the symbol is '>'
Now, sketch a number line and draw an open circle around the number 2.8.
You can see the number line as shown below in the attachment.
Answer:
Your answer would be 4, but correct me if I'm wrong.
Step-by-step explanation:
w(a)=3a to the power of 2+2; Find w(a-3) = 4
18/5 ÷2=18/5x1/2 =9/5
reciprocal=5/9
Answer: At least $91.91
Step-by-step explanation:
From the question, we are informed that to avoid a service fee, the checking account balance must be at least $500 at the end of each month.
Since the current balance is $525.17 and $117.08 has been spent, the balance will now be:
= $525.17 - $117.08
= $408.09
Since the checking account balance must be at least $500 at the end of each month and we currently have $408.09, this means that there will still be a need to add $91.91.
= $500 - $408.09
= $91.91
At least $91.91 must be added to avoid the fee.
