i read in class 4 but I don't explain the answer
Domain= [0,18], Range = [0,31.50]
If Charlie will only go to a single ride one time the possible rides he could go on would be 0 rides to all 18 rides for a domain of [0,18]. The output of the maximum and minimum x values would give us 0 dollars for riding 0 rides and 31.50 for riding all 18 (1.75 *0 = 0) and (1.75*18 = 31.50) so the range is [0, 31.50]
The sum of all angles in a triangle is always <em>180°</em>. Our triangle has <em>2</em> equal angles and one <em>40°</em> angle. That means that the size of those two angles is <em>(180° - 40° ) / 2 = 70°</em>. Then from <em>180°</em> or half circle subtract <em>70°</em> and you will end up with <em>110°</em> which the value of <em>x</em>.
Hope this helps.
