Solve for a.
√a-r +m=y

Step-by-step explanation:

√(a - r) + m = y

√(a - r) = y - m

(a - r) = (y - m)²

a = (y - m)² + r

a = y² - 2my + m² + r.

The answer is the 2nd option.

$119.20

step-by-step explanation:

$372.50 - 60% off is $149. $149-20% off is $119.20

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
