Answer:

x = 3/8 +/- i(√5)/8.

Step-by-step explanation:

I can't see any list by this is the solution of the equation:

x^2 - 3/4x = -1/4

x^2 - 3/4 x + 1/4 = 0

Multiply by 4 to remove the fractions:

4x^2 - 3x + 1 = 0

x = [-(-3) +/- sqrt(3)^2 - 4*4*1)] / 8

x = 3/8 +/-√ (-5) / 8

x = 3/8 +/-  √5 i / 8

On which number line do the points represent negative 4 and 1 over 2 and +3?
IceJOKER [234]

Answer:

Number line from negative 10 to positive 10 in increments of 1 is shown. Only the whole numbers are labeled. A point labeled R is placed between the 4th and 5th tick marks to the left of 0. A point labeled T is placed on the 3rd tick mark to the right of 0.

Step-by-step explanation:

The points given are (-4.5,0) and (3,0), which means the points are on the x-axis. Point R (-4.5,0) will be located to the left of 0, the negative side of the number line between the 4th and 5th marks. Point T (3,0) will be located to the right of 0, the positive side of the number line at the 3rd mark.

The second answer is incorrect because point (-4.5,0) is not on the right side of 0 but on the left side.

The third answer is incorrect because point T(3,0) is place between 2 and first mark instead of the third mark.

The fourth answer is incorrect because R (-4.5,0) is placed on the first mark instead of between 4th and 5th mark.
