The graph of g(x) is the graph of f(x)=x−2 reflected across the y-axis. which equation describes function g? g(x)=−2x+2 g(x)=x+2 g(x)=−x+2 g(x)=−x−2

The correct answer is g(x)=−x−2

Have fun studying!

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.
