7x + 1 = 2(2x - 1) + 3(x + 1)
7x + 1 = 4x - 2 + 3x + 3
7x + 1 = 7x + 1

x=4
Answer:
<em>-5, -3 = Quadrant |||</em>
Step-by-step explanation:
-3, 5 = Quadrant ||
4, 2 = Quadrant |
2, -4 = Quadrant |||| (Quadrant |||| is also known as Quadrant IV)

4x - 2y ≤ 6 <em>subtract 4x from both sides</em>
-2y ≤ -4x + 6 <em>change the signs</em>
2y ≥ 4x - 6 <em>divide both sides by 2</em>
<h3>y ≥ 2x - 3</h3>
y = 2x - 3 - it's a linear function. We need only two points to plot the graph.
Choose any two values of x and calculate the values of y:
for x = 0 → y = 2(0) - 3 = 0 - 3 = -3 → (0, -3)
for x = 2 → y = 2(2) - 3 = 4 - 3 = 1 → (2, 1)

Yes, f(x)=0 is a single-term polynomial.
However, its degree is undefined because of the 0.
