A- The circumference of the tire is about 7.85 feet
B- The tire will rotate about 672 times to travel 1 mile
Step-by-step explanation:
- The formula of the circumference of a circle is C = π d, where d is the diameter of the circle
- If a circle rotates for n turns and make a distance S, then n =

∵ The diameter of a tire is 2.5 ft
∴ d = 2.5 ft
∵ C = π d, where C is the circumference of tire
∴ C = π(2.5) = 7.85398 ft
∴ C ≅ 7.85 feet
A- The circumference of the tire is about 7.85 feet
∵ The tire have to travel 1 mile
∵ 1 mile = 5280 feet
∴ S = 5280 feet
- To find the number of rotation of the tire divide S by C
∵ n =
∴ n =
≅ 672 revolution
B- The tire will rotate about 672 times to travel 1 mile

If you want to write the equation of a line in the slope/intercept form, you have to write it as 
In other words, you have to solve for y. So, you simply have to subtract 3x from both sides:

Answer
x = 3, y = -1
Step-by-step explanation:
i used substitution because i find that easier most times so here goes:
x + 6y = -3
- 6y
x = -6y -3
now we have an "x=" to plug into the "y=" we will get ina second
2x + 3y = 3
-2x
3y = -2x + 3
divide the whole thing by 3 to get y by itself. you get:
y = -2/3x + 1
now plug in what you got for x, which was (-6y-3), into the x. so:
y = -2/3(-6y - 3) + 1
now you multiply the -2/3 by the -6y and the -3. when you distribute that you get
y = 4y + 2 + 1
then combine like terms by adding 2 + 1 to get 3 and subtracting the y on the right from the 4y on the left to get
= 3y + 3
since you cant have an empty side of the equal sign, move the 3y over to the left side by subtracting it. you get
-3y = 3 now divide everything by -3 to get y = -1
now you have your y variable so now just plug that into the original equation to get x + 3
HOPE THIS HELPS!!!
if you have more questions or didnt understand something, please let me know!! ill explain it!!
F(2) is the same as saying if x is 2 then what is y
