Use the zero product property to find the solutions to the equation 2x2 + x – 1 = 2.

FromTheMoon [43]

$2 {x}^{2} + x - 1 = 2$

Subtract sides -2

$2 {x}^{2} + x - 1 - 2 = 2 - 2$

$2 {x}^{2} + x - 3 = 0$

$(x - 1)(2x + 3) = 0$

_________________________________

$x - 1 = 0$

$x = 1$

##############################

$2x + 3 = 0$

$x = - \frac{3}{2} \\$

What does the number 2 represent in this function

romanna [79]

Your answer is C) The ant is crawling at 2 feet per minute.

This is because in the function y = 2t + 5, the 2 represents the slope of the line, which means that for every 1 unit that you go across, you need to go 2 units up. Therefore, for every 1 minute, the ant gains 2 feet so it is crawling at 2 feet per minute.

I hope this helps! Let me know if you have any questions :)
