Answer:
y = - x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 1 ← is in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
= - = - , thus
y = - x + c ← is the partial equation
To find c substitute (8, - 2) into the partial equation
- 2 = - 4 + c ⇒ c = - 2 + 4 = 2
y = - x + 2 ← equation of perpendicular line
0.00337837837 I think this because I got it off a calculator
I'm not entirely sure, but I believe its $7.95
This is how I got it:
8.00/100=0.08
(1.30+1.80+0.08)2 1/2 (or 2.5)
=(3.18)2 1/2
=7.95 ==========> $7.95
Again, I'm not 100% sure if this is correct...
If one adult ticket costs , then three adult tickets cost
Similarly, if one child ticket costs , then nine child tickets cost
So, in total, the price will be
