Answer:
<em>
</em>
Step-by-step explanation:
Functions have independet variables(the value of the variable could be any number, we have no restrictions) and dependent variaariables(the values of this variables depends of idependent variables)
the problem says that <em>x</em> is the independent variable, so we say that <em>y</em> is a dependent variable. Dependent need to be replaced by funcion notation, in this case we use <em>y=f(x)</em>
So we raplace it in the equation and we have:
<em>
</em>
we solve for <em>f(x)</em> passing <em>-6x</em> and <em>-9</em> to the right side and changing the signs, and we get:
<em></em>
Answer:
I am pretty sure it is 9
Step-by-step explanation:
Since a cube has the same with and length on every side is the same so I just do 3x3=9
To find the mean you add all the numbers then divide the sum by how many numbers there are :
1)Ford School
21+19+20=60
there are 3 numbers in the equation so you divide 60 by 3 :
60÷3=20
the mean for Ford School is 20
2)Carter School
41+36+37=114
there are 3 numbers in the equation so you divide 114 by 3 :
114÷3=38
the mean for Carter School is 38
hope this helps
Multiply amount sold by commission rate:
4500 x 0.13 = 585
She made $585 last week.
Multiply amount made in 1 week by 52 weeks ( 1 year = 52 weeks)
585 x 52 = 30,420
She made $30,420 in 2011
