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=

Reverse the table and observe
- For 1 month cost is 50
- For 2 months the cost is 100
See the pairs are (1,50) and (2,100) and so on
We know domain is set of x values and range is set of y values.
As there is no extra cost and the cost is 50$ per month cost depends upon the month means months are independent and cost is dependent , months are x and cost will be y then
The equation is
So here domain is all months
- {1,2,3,4,5,6,7,8,9,10,11,12}
If one angle is 80 degrees we can assume that each other angle must be 80, 100, and 100 degrees.
