Answer:

6x ≥ 3 + 8x - 4

01 ≥ 2x

0.5

Step-by-step explanation:

6x ≥ 3 + 4(2x - 1)

6x ≥ 3 + 8x - 4

6x ≥ 8x - 1

01 ≥ 2x

Answer:

6x <u>></u><u> </u> 3+4(2x -1)

6x <u>></u> 3+ 8x - 4

6x <u>></u> (-1) + 8x

6x - 6x <u>></u><u> </u> (-1) + 8x - 6x

subtracting 6x from both sides

0 <u>></u> 2x - 1

adding +1 on both sides

1 <u>></u> 2x

1/2 <u>></u> x

x <u><</u> 1/2

Which statement describes the effect on the parabola f(x)=2x•x-5x+3 when changed to f (x)= 2x•2-5x+1
o-na [289]

Answer:

The parabola is translated down 2 units.

Step-by-step explanation:

You have the parabola f(x) = 2x² – 5x + 3

To change this parabola to f(x) = 2x² - 5x + 1, you must have performed the following calculation:

f(x) = 2x² – 5x + 3 -2= 2x² - 5x + 1  <u><em>Expresion A</em></u>

The algebraic expression of the parabola that results from translating the parabola f (x) = ax² horizontally and vertically is g (x) = a(x - p)² + q, translating in the same way as the function.

  • If p> 0 and q> 0, the parabola shifts p units to the right and q units up.
  • If p> 0 and q <0, the parabola shifts p units to the right and q units down.
  • If p <0 and q> 0, the parabola shifts p units to the left and q units up.
  • If p <0 and q <0, the parabola shifts p units to the left and q units down.

In the expression A it can be observed then that q = -2 and is less than 0. So the displacement is down 2 units.

This can also be seen graphically, in the attached image, where the red parabola corresponds to the function f(x) = 2x² – 5x + 3 and the blue one to the parabola f(x) = 2x² – 5x + 1.

In conclusion, <u><em>the parabola is translated down 2 units.</em></u>
