487 rounded to the nearest ten is 490......because 487 is closer to 490 then it is to 480.
Part A:
<span>a system of inequalities that only contain points D and E in the overlapping shaded regions is
5y + 2x > 12
2y - x < 12
Part B:
To verify that points D and E are solutions to the system of inequalities, we plug in the coordinate points of points D and E into the system of ineaqualities.
Part C:
</span>To <span>identify the schools that Timothy is allowed to attend we plug in the coordinate values of the points to see which satisfies the inequality y < 3x - 3. Thus Timothy is allowed to attend schools C and F.</span>
180= 56+2u+2u
180=56+4u
u= 31
First we see there are two extremes, two limits
-2 and 5
x is between them
BUT theres a difference , the point at left is black
the point at right is white rounded
this means x is equal or less than -2
and x is ONLY less than 5 , not equal
so this means the answer is the d option
