The given expressions are 
and 
We have to find the sum of the given expressions,
Combining the like terms of both the expressions, we get
=
.
A there are no real zeros
using the discriminant b² - 4ac to determine the nature of the zeros
for y = x² + 4x + 5 ( with a = 1, b = 4 and c = 5 )
• If b² - 4ac > 0 there are 2 real and distinct zeros
• If b² - 4ac = 0 there is a real and equal zero
• If b² - 4ac < 0 there are no real zeros
b² - 4ac = 16 - 20 = - 4
Since discriminant < 0 there are no real zeros
14n+ 4 = 2( 7n + 2 ) ; the factors are 2 and ( 7n + 2 ) ;
Answer:
D) y greater than equal to -1
Step-by-step explanation:
As in the graph, the line passes through y = -1 and the shaded art is above the line so all the values greater than y = -1 match the graph.
Mathematically:
y ≥ -1
