Step-by-step explanation:
<u>Step 1: Define</u>
x³ + 3x² = x + 3
x = -1
<u>Step 2: Check</u>
- Substitute in <em>x</em>: (-1)³ + 3(-1)² = -1 + 3
- Evaluate exponents: -1 + 3(1) = -1 + 3
- Multiply: -1 + 3 = -1 + 3
- Add: 2 = 2
Answer:

Step-by-step explanation:
line segment AB is a chord.
Answer:
D
Step-by-step explanation:
In a triangle, the sum of three angles is 180.
Since 50+65+80= 195 does not equal to 180.
Therefore, we choose D.

Answer:
-1/2
Step-by-step explanation:
The constant in the equation is the value that y has when x=0, because the x-term evaluates to zero when x=0. The constant term in this equation is -1/2, so that is the y-value when x=0.
(x, y) = (0, -1/2) . . . . where the graph crosses the y-axis
