2 answers:
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
2y > x-2
The solution of this inequality is the shaded area above the dotted line 2y=x-2
The graph in the attached figure
<u>Answer:</u>
Third graph
<u>Step-by-step explanation:</u>
We are determine whether which of the given graphs is that of the linear inequality .
We know that, on the graph the greater than sign () represents the shaded part above the line and less than sign (
) represents the shaded region below the line.
While the signs or
is denoted by a solid line on the graph.
Therefore, the third graph represents the given inequality.

Answer:
No, the following expression is not a difference of squares. Binomial can not be factored as the difference of two perfect squares. 3 is not a square.
Step-by-step explanation:
Factor
15x^2 - 25
(15x)^2(-5)^5
Divide by 3 and factor
5(3x^2-5)
"Theory:
A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression."
