Step-by-step explanation:
Equ of line -
y=mx+c
Using point (3,-1)
3 as x, - 1 as y
M=2/3
Substitute the values of these coordinates
3=2/3(-1) +c - - - - now find for c
c= 3- (-2/3)
c= 3.67
Now with the value of c, put the values back into the equation form .. Assuming we don't have a point to work with
y=2/3x + 3.67
Answer: with 11 miles, it can travel 220 miles
Answer:Then correct option is A
Step-by-step explanation:
The correct option is A
because 3^2+4^2=5^2 based on Pythagoras principle
As a property of equations, you can add or subtract the same quantity to/from both sides, and the truth value of the equality will remain the same: if you start with something true, e.g. 7=7 and add the same quantity to both sides, e.g. 7+4=7+4, you will still have something true, i.e. 11=11.
On the other hand, if you start with something false, e.g. 3=7 and add the same quantity to both sides, e.g. 3+6=7+6, you will still have something false, i.e. 9=13.
So, you can subtract 
from both sides to transform the equality into
as required.
Sales tax = 7.5%
7.5% of 12.50 = (7.5/100) * 12.5 = 0.075* 12.5 = 0.9375
tax = 0.9
Total pay = price + tax = 12.5 + 0.9375 = 13.4375
Total pay ≈ 13.44
Hope this solves it.
