 x: number of hats
 y: number of scarves
 We have the following equations:
 x / y = 4/3
 x-25 / y = 7/9
 Solving the system of equations we have
 x = 60
 y = 45

Triangle ABC has vertices at (3,1) and (6,4).Rotate this triangle 180 degrees about the origin then reflect it over the Y-Axis.
Tems11 [23]

Answer:

3, -1

6,-4

IDK about the third vertices, you didn't give the original coordinates!

Step-by-step explanation:

180 degree rotation= (x,y) to (-x,-y)

3,1 goes to -3,-1

6,4 goes to -6, -4

IDK about the third vertice, you didn't mention it.

Reflection over y-axis= (x,y) to (-x,y)

-3, -1 goes to 3, -1

-6,-4 goes to 6,-4

hope this helps!

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra I</u>

  • Terms/Coefficients
  • Factoring
  • Standard Form: ax² + bx + c = 0
  • Solving quadratics

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

4x² + 3 = 4x + 2

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. [Equality Property] Rewrite in standard form:                                                 4x² - 4x + 1 = 0
  2. Factor:                                                                                                               (2x - 1)² = 0

lesya [120]

Answer: 7 clients

Step-by-step explanation:

Of the last 10 clients that cut their hair at the salon, 5 had blond hair.

That is a proportion of:

= 5 / 10

= 1/2

Assuming this same proportion applies to the next clients Sue gets, the expected number of blonde people will be:

= Number of clients * 1/2

= 14 * 1/2

= 7 clients
