Step-by-step explanation:
Using Descartes' rule of signs, you can determine there are zero negative real roots. The above answer choice is the only one with no negative zeros listed.
_____
The count of negative real roots is based on the number of sign changes when the signs of odd-degree terms are reversed. Doing that gives the signs of the terms as - - - -, so there are no changes. That means there are no negative real roots.
A graphing calculator confirms this choice.
Answer:
First row: 5(1)-4; 1; (1,1)
Second row: 5(2)-4; 6; (2,6)
Third row: 5(3)-4; 11; (3,11)
Step-by-step explanation:
Plug in the value of x to get the value for u then write the coordinates. So first value of x is 1 so put a 1 where the x is in this equation 5x -4. 5(1) - 4 =1 so the value of y is 1. So when x is 1 y is equal to 1 (1,1). Do the same for 2 and 3.
