Square ABCD was translated using the rule (x, y) → (x – 4, y + 15) to form A'B'C'D'. What are the coordinates of point D in the

Vitek1552 [10]

Answer:

D = (13, - 23 )

Step-by-step explanation:

Given the translation rule

(x, y ) → (x - 4, y + 15 )

To go in the reverse direction, that is image to original, then, reverse the operations in the translation rule.

(x , y ) → (x + 4, y - 15 ) , thus

D'(9, - 8 ) → D(9 + 4, - 8 - 15 ) → D(13, - 23 )

X²-x-6 What is hcf of the polynomial

Eva8 [605]

Answer:

the highest common factor of the polynomial is (x + 2) (x - 3)

Step-by-step explanation:

The computation of the highest common factor of the polynomial is as follows:

According to the question, the following equation is given

' $x^2 - x - 6$

Now do the factorization

$x^2 -3x + 2x - 6$

x(x - 3) +2 (x - 3)

(x + 2) (x - 3)

hence, the highest common factor of the polynomial is (x + 2) (x - 3)

The same is to be considered

Find the rate if the principal is $900, the time is 3 years, and the interest is $135. A) 5% B) 7.5% C) 15% D) 20%

Rus_ich [418]

The answer would be A) 5%. You can solve this by dividing 135$ by three years to get 45. then divide 45 by 900 to get 0.05 which is 5% in decimal form.
