The value of almost everything you own (assets), such as a car, computer, or house, depreciates (goes down) over time. when an asset’s value decreases by a fixed amount each year, the depreciation is called straight-line depreciation. suppose your truck has an initial value of $12,400 and depreciates $820 per year. what two variables are involved in this problem? which variable can best be designated as the dependent variable? as the independent variable?

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.

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
