5x + 34 = -2(1 - 7x)
5x + 34 = -2 + 14x
36 = 9x
x = 4
NO = -2(1 - 7*4)
NO = -2(1 - 28)
NO = -2 + 56
NO = 54
There is no rate of change of Function 1. It's slope(rate of change) is zero.
Function 2 has a slope of 2.
You can give random values such as <span> (1,2.5) (2,9) (-1,2.5) (-2,9) and it is a parabola. You'll see that the range is (-infinte, 0] and the domain is (-infinit, infinite). </span>I hope that this is the answer that you were looking for and it has helped you.
15.49x = 13.99x + 6
15.49x - 13.99x = 6
1.50x = 6
x = 6 / 1.50
x = 4 <=== u can buy 4 DVD's for the same amount
15.49 * 4 = 61.96
13.99(4) + 6 = 61.96
