kakasveta [241]

Answer:

Slope is -11/6

Step-by-step explanation:

Given \:   points \:   are \:    (10,4) \:  \: and \: (4,15) \\ slope \:  =  \frac{y2 - y1}{x2 - x1}  \\ here \: x1 = 10 \:  \:  \: y1 = 4 \\ and \:  \: x2 = 4 \:  \:  \: and \:  \: y2 = 15 \\ on \: substituting \: the \: values \: in \: formula \\ slope =  \frac{15 - 4}{4 - 10}  \\  =  \frac{11}{ - 6}

Which equation has exactly two real and two non real solutions?
tatiyna

Answer:

The first option x^4-21x^2-100=0.

Step-by-step explanation:

To have exactly 2 real and two non real solutions, the degree of the polynomial must be a degree 4. Degree is the highest exponent value in the polynomial and is also the number of solutions to the polynomial. This polynomial ha 2 real+2 non real= 4 solutions and must be x^4. This eliminates the bottom two solutions.

In order to have two real and two non real solutions, the polynomial must factor. If it factors all the way like

x^4-100x^2=0\\x^2(x^2-100)=0\\x^2(x-10)(x+10)=0\\\\x^2=0\\x-10=0\\x+10=0

This means x=0, 10, -10 are real solutions to the polynomial. It has no non real solutions. This eliminates this answer choice.

Only answer choice 1 meets the requirement.
