What is the discriminant of the quadratic equation 4x^2-7x-6=04x 2 −7x−6=0?

  145

Step-by-step explanation:

The discriminant of quadratic ...

  ax^2 +bx +c = 0

is ...

  d = b^2 -4ac

For your quadratic, you have a=4, b=-7, c=-6, so the discriminant is ...

  d = (-7)^2 -4(4)(-6) = 49 +96 = 145

The discriminant is 145.

50-38=12

step-by-step explanation:

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
