Answer:2,2
Step-by-step explanation:
I remember doing this last year
Given:
The cost y (in dollars) of renting a segway for x hours is

To find:
The initial fee and the cost per hour.
Solution:
We have,
...(i)
The slope intercept form of a linear equation is
...(ii)
where, m is slope is b is y-intercept or initial value.
From (i) and (ii), we get

The value of m is 30, so the slope is 30. It means cost per hour is $30.
The value of b is 25, so y-intercept is 25. It means the initial fee is $25.
Answer:
x=0.25 or -1/4
Step-by-step explanation:
120x + 21 = -9
120x = -30 (-21 from both sides of equation)
x = -0.25 or -1/4 (divide 120 from both sides of equation)
Answer:
h = b(√3)/2
Step-by-step explanation:
The ratio of base to height of an equilateral triangle is ...
... b/h = 2/√3
Multiplying both sides of the equation by (√3)h/2, we get
.. h = b(√3)/2 . . . . . . your equation with h as the subject
