equation?

OpenStudy (anonymous):

nopee

OpenStudy (anonymous):

u need a question

OpenStudy (anonymous):

graph

OpenStudy (anonymous):

sing graphing technology, approximate where the graph of y = 2x2 − 8x − 5 crosses the x-axis. (4.55, 0) and (−0.55, 0) (4.23, 0) and (−0.46, 0) (4.32, 0) and (−0.49, 0) (4.48, 0) and (−0.51, 0)

OpenStudy (anonymous):

solve the equaton 2x^2-8x-5=0 you'll get certainly two solutions ! choose your answer like (solution1,0) and (solution2,0)

OpenStudy (anonymous):

why is thre more then one quesiton asked

OpenStudy (anonymous):

x=4.54,-0.54

OpenStudy (anonymous):

nope

OpenStudy (anonymous):

huh?

OpenStudy (anonymous):

so ; If the soltutions are 4.54 , -0.54 so I guess the first one is the good one !

OpenStudy (gabylovesyou):

The first one :) (let me double check)

OpenStudy (gabylovesyou):

the gpah crosses x-axis only when y=0 so we need to solve 2x^2-8x-5=0

OpenStudy (gabylovesyou):

yea its A :)
