f(x) = 10 + 20x
so if you rent the bike for a few hours that is
1 hr.............................10 + 20(1)
2 hrs..........................10 + 20(2)
3 hrs..........................10 + 20(3)
so the cost is really some fixed 10 + 20 bucks per hour, usually the 10 bucks is for some paperwork fee, so you go to the bike shop, and they'd say, ok is 10 bucks to set up a membership and 20 bucks per hour for using it, thereabouts.
f(100) = 10 + 20(100) => f(100) = 2010.
f(100), the cost of renting the bike for 100 hours.
Similar triangles are triangles in which its corresponding
interior angles are congruent. Since the triangle n and triangle m are similar
so the triangle n has also the same interior angles with triangle m. triangle n
interior angles are alos two 32 degrees angle and one 93 degrees angle
Perimeter is 2L + 2W
Now plugging in for values we know
42=2L + 2(7)
Move the 14 to the other side to isolate the variable L
28=2L
Divide by 2
L= 14 feet
L is length
Number is x
3 times of x is increased by 22, that euals 14 less than 7 times x
3x+22=-14+7x
minus 3x both sides
22=-14+4x
add 14 to both sides
36=4x
divide both sides by 4
9=x
the number is 9
