Answer:

a. Parallel

b. Not parallel

Step-by-step explanation:

Systems which have no solutions are parallel lines. These lines do not intersect and therefore have no solution. Remember, parallel lines have the same slope. Compare the slope in each equation when in y=mx+b format to see if they are parallel.

a. y= 2x + 3                                                  y-2x=-3 becomes y = 2x - 3

m = 2                                                            m= 2

The slopes are the same so these are parallel lines.

b. 3x + y = 2 becomes y= -3x + 2               y = 1/3 x + 1/2

m = -3                                                          m= 1/3

The slopes are different so this is not parallel.

Since -3 and 1/3 are the negative reciprocals of each other. These lines are actually perpendicular.

Use the quadratic formula to determine the exact solutions to the equation. 6x2+4x−3=0 Enter your answers in the boxes. x = or x
Black_prince [1.1K]
The quadratic formula is x= -b +/- √b²-4ac / 2a

In this problem,

a=6
b=4
c=-3

Now, we can plug this into the formula:

x= -4 +/- √4²-(4)(6)(-3) / (2)(6)
x= -4 +/- √16+72 / 12
x= -4 +/- √88 /12
x= -4 +/- 2√22 /12
x= -2 +/- √22 / 6

So,

x= -2 + √22 / 6
x= -2 - √22 / 6
