What is the domain and range of f(x)=9−x2−−−−−√+4? HELPPP A)The domain is [0,3], and the range is [4,∞). B)The domain is (0,3), and the range is (4,∞). C)The domain is [−3,3], and the range is [4,7]. D)The domain is (−3,3), and the range is (4,7).

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

idk

step-by-step explanation:

use that smart brain

answer: my brother can figure it out, imma go get him so i can answer : ) edit: my brother is sleeping, sorry man

step-by-step explanation:

y-3=-3/2(x+4)

ur very much welcome
