Kiera is in her last year of college at the University of Houston. She has a scholarship that pays 75% of her costs. Her classes
sergiy2304 [10]
If the scholarship pays 75% of her classes cost, that means that she has to pay the 25% remaining of the classes cost so if we calculate it as follow:

0.25 * $14,000 = $3,500 
 =================================================================
Another method to understand:
if the scolarship pays 75% of her classes that will be 
0.75* $14,000 = $10,500

now she has to pay the remaining of the total cost and that will be 
$14,000 - $10,500 = $3,500.

What is the rule used to reflect the triangle ABC to its image?
Debora [2.8K]

Answer:

The rule used to reflect Δ ABC to its image is Reflect over y = x ⇒ B

Step-by-step explanation:

  • If the point (x, y) reflected across the x-axis , then its image is (x, -y)
  • If the point (x, y) reflected across the y-axis , then its image is (-x, y)
  • If the point (x, y) reflected across the line y = x , then its image is (y, x)
  • If the point (x, y) reflected across the line y = -x , then its image is (-y, -x)

From the given figure

∵ The coordinates of point A are (-4.5, 6)

∵ The coordinates of point A' are (6, -4.5)

→ The coordinates are switched ⇒ 3rd rule

∴ Point A is reflected over the line y = x

∴ Δ ABC is reflected over the line y = x

∴ The rule used to reflect Δ ABC to its image is Reflect over y = x

<em>Note: Point B' on the graph should be C' and point C' should be B' (correct it)</em>
