Step-by-step explanation:
The scientific notation:
<em>1 ≤ a < 10</em> and <em>k -</em><em> any integer number</em>

Answer:
0.8
Step-by-step explanation:
3(5x+2)+10=4
=15x+6+10=4
After this step you subtract 6 from each side and then subtract 10 from each side and then after that you divide 15x on each side which will give you 0.8.
Answer:
0
Step-by-step explanation:
-14 is also equal to 0
cause it does not have any value
5% of 210000=
(210000/100)5= $10500 anually
so 4 years will be $42000
he'll pay 42000 + 210000
$252000
answer is B
Answer:
B. y= -x^2+50x-300
Step-by-step explanation:
A. y^2=4x^2-100
B. y= -x^2+50x-300
C. x=-y^2-400
D. x^2=-6y^2+200
we are to find profits (y) when the company sells x items
Option A can be used to calculate the profit (y) squared
Option B can be used to calculate profits (y)
Option C can be used to calculate items sold(x)
Option D can be used to calculate items sold squared(x^2)
We are asked to find the weekly profit (y) function which eliminate options A, C and D leaving us with option B
Therefore, the weekly profits (y) function in thousands of dollars when the company sells x items is
B. y= -x^2+50x-300
