Solve by using tables. give each answer to at most two decimal places. –2x2 – 4 = –8x (1 point) 0.59, 3.41 –3.41, –0.59 1.17, 6.83 –1.41, 1.41

The solution to the quadratic equation x² - 4x - 2 =0 is 0.59 and 3.41

Step-by-step explanation:

Given the equation -2x² - 4 = -8x

rearrange the equation we now have -2x² +8x - 4 = 0

divide each term in the equation by -2, we have

x² - 4x - 2 =0

To get the table, we substitute the given values of x in the equation to get the corresponding values for y

x values     y values

0.59            -0.0119

3.41              -0.0119

-3.41              27.2681

-0.59            4.7081

1.17                -1.3111

6.83             21.3289

-1.41              9.6281

1.41               -1.6519

The two points of x where y =0 are 0.59 and 3.41

Therefore the solution to the quadratic equation x² - 4x - 2 =0 is 0.59 and 3.41

i got 86 for this

hope this !

if you need an explanation just ask

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
