You need to solve for each value x and y. These two equations provide the intersection of both whereby
y=2x-4 and y=x-1
this gives us, by replacing y in the first equation with x-1 = 2x-4
subtract the left side x from the right side gives us -1 = x - 4
subtracting known values x = 3
verfy the results gives us 2(3) - 4 = y
2 = y
also 3 - 1 = y
2 = y
so you wind up with x = 3 and y = 2
1 mile = 1.61 kilometers
4 miles = 6.44 kilometers
The answer is: The product
is a radical multiplied by an integer and the result is ![10.58](https://tex.z-dn.net/?f=10.58)
By definition, the set of integers has: negative numbers, positive numbers and zero.
Radicals are also known as roots and can be written with the symbol:
![\sqrt[n]{} ](https://tex.z-dn.net/?f=%20%5Csqrt%5Bn%5D%7B%7D%20%0A%20)
, where "n" is the index.
Normally, when a radical is multiplied by an integer, you must simplify it, but in this case you can calculate the result by using your calculator.
