This is basically asking if each transformation is an isometry, which maps a triangle to a congruent triangle.

(x,y)⇒(-y,x)  That's an isometry, not scaling x or y.  I think it's a 90 degree rotation.  CONGRUENT

(x,y)⇒(x-2,y-1/2)  No scaling, pure translation. CONGRUENT

(x,y)⇒(2x,2y)  That's a double scaling so NOT CONGRUENT

(x,y)⇒(-x,y)  That's a reflection.  CONGRUENT

(x,y)⇒(1/2 x, 1/2 y) Scaling again, NOT CONGRUENT

Ill mark brainliest!!
Anastasy [175]

Answer:

$60

Step-by-step explanation:

So from the question, we need to find the fixed amount for the tv's. So we have to make an equation, and don't forget to add the extended warranties:

11(x + 25) = 935

x will represent a tv, and the 25 is the extended warranty for a tv, since the questions states 11 tv's with warranties is 935, the equation will look like that. Now lets slove:

11(x + 25) = 935

multiply

11x + 275 = 935

subtract 275 from both sides

11x = 660

divide both sides by 11

x = 60, each tv is $60

What is the cost of each item? What is the subtotal? What is the tax? What is the total paid? Shoes: $49.99 (normally) they are
prisoha [69]

Answer:

Cost of shoes = $37.4925

Cost of jacket = $92.4533

Tax = $9.81

Total paid = $144.2458

Step-by-step explanation:

Normal price of shoes = $49.99

Discount = 25%

Discounted price:

\$49.99 - \$49.99\times \dfrac{25}{100} = \$37.4925

Normal price of jacket = $137.99

Discount = 33%

Discounted price:

\$137.99 - \$137.99\times \dfrac{33}{100} = \$92.4533

Price of pack of cookies = $4.49

No discount on cookies as per question statement.

Total amount without tax = $37.4925 + $92.4533 + $4.49 = $134.4358

Sales Tax = 7.3% of total amount without tax = 7.3% \times $134.4358 = $9.81

Total paid = $134.4358 + $9.81 = <em>$144.2458</em>
