Answer:
7900 and 500
Step-by-step explanation: While rounding if the number by the digit next to the place value we are rounding to (the 10's place value while rounding to the nearest hundred for example) is greater than 5, then you round up, if not, round down
7892 = 7900
472 = 500
Step-by-step explanation:
ANSWER
(2,2)
EXPLANATION
Since f(x) and its inverse function are symmetric about the line y=x, if (a,b) lies on the graph of f, then (b,a) must lie on f inverse.
The point (2,2) lies on f and the same time on f inverse.
The solution is a point that satisfies both equations.
Hence the correct choice is:
3:5
60:100
90:150
120:200
15:25
150:250
180:300
210:350
the answer is:
x=6
y=7
it's easy..here have a look at it.
