Answer:
Graph A: two distinct roots. Graph B: one repeated real root. Graph C: two complex roots. Graph D: two distinct real roots.
Step-by-step explanation:
Explanation:
Each graph represents a quadratic function. So by the fundamental theorem of algebra, we know that each graph will have two roots.
Graph A crosses the x-axis twice. So, graph A has two distinct real roots.
Graph B touches the x-axis once. A quadratic cannot have one real root and one complex root. So it must have one repeated real root.
Graph C doesn’t cross the x-axis. This means it must have two complex roots.
Graph D crosses the x-axis twice. So, graph D has two distinct real roots.
Answer:
x=12
Step-by-step explanation:
63+8x-17+3x+2=180
48+11x=180
11x=132
132/11=12
