ich sequence of transformations would result in a figure that is similar, but not congruent, to the original figure? Select all

that apply. a dilation with a scale factor of 0.6 followed by a translation of 2 units up a reflection across the y-axis followed by a rotation about the origin of 10 a translation 2 units up followed by a translation of 2 units to the left a rotation about the origin of 50° followed by a dilation with a scale factor of 8

Translations, reflections, and rotations always result in a figure that is congruent. Only dilations with a scale factor other than 1 will give a similar, but not congruent, figure.

The 1st and 4th selections apply.

What is the root of the polynomial equation x(x-2)(x+3) = 18? Use a graphing calculator and a system of equations.
Trava [24]

9514 1404 393

Answer:

  x = 3

Step-by-step explanation:

The equation can be rewritten to make use of the graphing calculator's ability to identify function zeros:

  x(x -2)(x +3) -18 = 0

The attached shows x = 3 is the only real solution.

_____

We're not sure what "system of equations" is intended. Perhaps it is ...

  y = 18

  y = x(x -2)(x +3)

To create the expression we graphed, we effectively subtracted the first equation from the second.

Convert from Standard Form to Slope Intercept Form<br> 3x + 2y = 6
Ilia_Sergeevich [38]

Answer:

y = -3/2x + 3

General Formulas and Concepts:

<u>Algebra I</u>

Equality Properties

Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

Standard Form:   3x + 2y = 6

<u>Step 2: Find slope-intercept form</u>

  1. Subtract 3x on both sides:          2y = 6 - 3x
  2. Divide both sides by 2:                y = 3 - 3/2x
  3. Rewrite:                                         y = -3/2x + 3

And we have our final answer!

Helpppppppp? please thank you
Snezhnost [94]

The x values are the same for both green dots, so you are looking at a simplified version of the distance formula.

d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )

Since x1 = x2 = 5, the first set of brackets = (5 - 5) = 0

d = sqrt( y2 - y1)^2 )

d = y2 - y1

y2 = 5

y1 = - 1

d = 5 - - 1

d = 6    Answer
