28.3 / 9 = 3.14444444......
3.14 round to 3
Inequation:
90x-150y>=700
x<=40
y<=62
x is the days she works and y is the days she travels.
equation:
90x-150y=700 (although the equation will be less accurate than the inequation)
The graph represents a parabola which opens towards right . ANd for such parabola, the equation of the parabola is

Here the vetex, (h,k) is (1,2).And it passes through point (2,5) . So on substituting these values, we will get

So the required equation is

Step-by-step explanation:
6x = 64
so, x = 64 / 6
_____
x = 10.6
