Which graph shows a mixed-degree system with exactly one solution? its d the last one.

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

step-by-step explanation:

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
