X²+14x+49+17=-96+49
(x+7)²=-64, x+7=±8i, x=-7±8i, so x=-7+8i or -7-8i.
Answer:
25/4 75/8
25/4= 6.25
and 75/8= 9.375
and 9.375/6.25 = 1.5
Step-by-step explanation:
We are to select 2 people to sit in first row from 6.
This is a problem of Combinations. We are find permutation of 6 people taken 2 at a time. This can be represented as 6C2.
So, the answer is option B
The Piecewise -Defined function and how it is graphed is given below..
<h3>What is the explanation of how the
Piecewise -Defined function is graphed?</h3>
Given the function in the attached image,
- The Graph of f(x) = -x + 3 is drawn for x less than 2 because x is bounded.
- The Graph of f(x) = 3 is draw for x greater than and equal to 2 and less than 4 because x is bounded.
- The Graph of f(x) = 4 - 2x is draw for x greater than equal to 4 because x is bounded.
See the attached Graph for better understanding.
- f(x) = -x + 3 is coded purple.
- f(x) = 3 is coded orange.
- f(x) = 4 - 2x is coded green.
