To find the inverse, switch the x and y, and then solve for y (f(x) is the same as y)
So we get:
x=1.50y-30 (add 30 to both sides)
x+30=1.50y (divide both sides by 1.5)
x/1.5+30/1.5=y
y=x/1.5+20
Hope this helps
84= 7(6+a)
84= 42 +7a
84-42= 42-42 +7a
42= 7a
42/7= 7a/7
6= a
-84= -6( p+6)
-84= -6p -36
-84+36= -6p -36+36
-48= -6p
-48/-6= -6p/-6
8 =p
We know that
<span>Each pie was cut into six slices
</span><span>there are a total of 48 pieces-----> divide by six to find the number of pies
48/6----> 8 pies
</span><span>Two of the pies will be served to members of the department as courtesy
</span>so
subtract 2 to the total of pies to find the pies available for sale
<span>whole pies available for sale=8-2-----> 6 pies
the answer is
6 pies</span>
