Answer:
Step-by-step explanation:
A taxi costs $2.50 for the first mile and $1.75 for each additional mile.
Let x be the miles traveled
Taxi cost 2.50 for first mile , so we find the cost of x-1 miles
total cost for x miles traveled is
Giselle has $16.25 in her wallet
total cost is less than 16.25

Answer:
27y
Step-by-step explanation:
3×9=27×y = 27y
all is shown
2 and 3/5 boxes because 1/5 + 2/5 = 3/5, and 2 + 3/5 = 2 and 3/5
A. Yes you are correct that the gradient at any point is 3/(3x-1). However at point P it would be 3/(3*2-1)=2/5
b. The gradient of the normal would therefore be -5/2
We can use the general formula of an equation to get y-ln(5)=-5/2 (x-2)
Now multiply both sides by 2 to get:
2y-2ln(5)=-5x+10
Now when it crosses the x axis we know that y=0 therefore:
5x=10+2ln(5)
Therefore:
x=2+2/5 ln(5) when y=0
You could find an estimate of this number to be 2.64 (3sf) but this might not be sufficient
