Answer:

Exactly one solution.

Step-by-step explanation:

2x-4y=8

x+2y=4 /*2

2x-4y=8

2x+4y=8 (+)

4x=16

x=4

4+2y=4

y=0

(x;y)={(4; 0)}

Exactly one solution.

Using the graph as your guide, complete the following statement.

ollegr [7]

Answer:

positive

Step-by-step explanation:

the discriminant of the function is postive.

because from the graph we notice that it has 2 intercepts on x-axis, which means the function has 2 real solution when y=0

that implies the discriminant is positive.

$\Delta = \sqrt{b^2-4ac}$

if $\Delta > 0$ we have 2 distinct real solution

if $\Delta$ we have no real solution but 2 complex solutions

if $\Delta = 0$ we have 2 identical real solution
