Answer:
Step-by-step explanation:
y-x=0.7
y=x+0.7, so lets plug in that into the expressions instead of y
1)
(y-x)=
x+0.7-x=
x+0.7+(-x)=
x+(-x)+0.7=
x-x+0.7=
0.7
2)
(x-(x+0.7))/((x+0.7)-x)=
(x-x+0.7)/(x+0.7-x)=
(x-x+0.7)/(x+0.7+(-x))=
(x-x+0.7)/(x+0.7+(-x))=
(x-x+0.7)/(x+(-x)+0.7)=
(x-x+0.7)/(x-x+0.7)=
0.7/0.7=
1

Step-by-step explanation:
F(x)=8(1.25)^x----F(x)= 1000--Plug in known variables----1000=8(1.25)^x--Divide by 8--------125=1.25^x----1.25^21.6377~=125-- Reformat--- 8*1.25^21.6377 close to 1000 could round it to any decimal place you want. Hope this helps
The cost of a visit is 50 + 100n where n is the number of cavities found. Since 2 cavities were found, simply plug in 2 for n.
50 + 100(2) = 50 + 200 = $250 (assuming the currency is US Dollars)
