We can use using graphing technology to solve the system of equations here.
So draw sketch of graphs and
on graphing calculator. you will get sketch as shown
Take pointer to point of intersection as shown. It displays (x,y) coordinate of points of intersection as (9.597, 3.459) as show in figure.
Now round off these values to nearest tenth thats one digit after decimal dot.
so to round 9.597 to one decimal place we will see 2nd decimal digit(next to place where you have to round off) which is 9 here and as 9 is greater than 5 so we will increase 1st decimal place digit by 1, so round to one decimal place will be 9.6.
Similarly to round off 3.459 to one decimal place we will see 2nd decimal digit which is 5. Again as its equals 5 we will increase the 1st decimal digit by 1 for round off. So final round off to one decimal place will be 3.5
So final answer for solution set will be choice C (9.6, 3.5)
