Answer:

(b) reduce the variability of the poll result.

Step-by-step explanation:

Which of the following equations has the same solutions as x^2+8x+2=0
denis23 [38]

Answer:

See below

Step-by-step explanation:

Need the choices.....

     essentially,  you can multiply this equation  by any constant to get an equivalent equation with the same solutions.

x^2 + 8x + 2 = 0      multiply both sides by '3' to get

3x^2 + 24 x + 6 = 0     <===== this will have the same solutions

    or this one:

x^2 + 8x + 2  = 0            Multiply both sides by   '6' to get

6x^2 + 48x + 12 = 0      <===== this will have the same solutions also

etc....

Slope is -2 and y-intercept is -6 how do I write the linear equation in slope intercept form
PtichkaEL [24]
You need to write it in the form y = mx +b 
since slope is m and b is the y-intercept, it would be written as y = -2x + -6

I hope this helped :)
