Answer : option D
we need to find out the graph shows a mixed-degree system with exactly one solution
The solution of two graphs will be the intersection of two graphs
In the first graph,
There is no intersection of both circles, So no solution
second graph,
The circle intersects the parabola at two point, so two solution for this graph
Third graph,
The circle and line does not intersects, so no solution
Fourth graph,
Both parabola intersects at one point, so one solution for this graph
So option D has exactly one solution
<span>Find the place value you want (the "rounding digit") and look to the digit just to the right of it.<span>If
that digit is less than 5, do not change the "rounding digit" but
change all digits to the right of the "rounding digit" to zero. hope this helps</span></span>
2 out of 50 are defective.
Divide 2 by 50: 2/50 = 0.04
Now multiply the total quantity by that:
2000 x 0.04 = 80
80 are likely to be defective.
1 yard = 3 feet
300 yards = (3 ft) x (300) = 900 feet
<em>1,000 feet</em> is larger than 900 feet. It's also longer and farther.
