A² + b² = c²
a² = c² - b²
a² = 9² - 6²
a² = 81 - 36
a² = 45
a = √45
a ≈ 6.7082
a = 6.7
You want to get the total amount Henri has which is $14 then subtract the flat fee.
14-1.25=12.75, He has $12.75 left to pay for miles, Since the taxi charges .75 a mile, you get $12.75/.75= 17
Henri has enough to pay to ride 17 miles.
Hope this helps
Y = (2/3)x + 4
The slope of the line is 2/3 and the y-intercept is 4
You do 6.394-3.200 which =
3.194
