(15-6)-3 = 15 - (6 -3) dose this make sense or nonsense?

solmaris [256]

No it does not make sense. You misused the parenthesis and the "-" multiplied the variables within the parenthesis and as a result one of them subtracted (15 - 6) by 3 and the other added, which is why the final values are 6 apart. This is not how you use properties in math.
(15 - 6) - 3 = 9 - 3 = 6
15 - (6 - 3) = 15 - 3 = 12

Make ratios.

12/16: 15/x

cross multiply

12(x) = 12x
16(15) = 240

12x = 240

isolate the x, divide 12 from both sides

12x/12 = 240/12

x = 20

D) 20 km is your answer

What is the average rate of change of the function over the interval x = 0 to x = 8?

notsponge [240]

To find the average rate of change, use the following formula:

$\frac{f(b) - f(a)}{b-a}$

a and b represent the values of the interval:

$a = 0, b = 8$

Simplify the original equation by combining like terms:

$2x - 13x = -11x$
$f(x) = -11x + 5$

Plug the interval values into the f(x) equation:

$f(0) = -11(0) + 5 = 0 + 5 = 5$
$f(8) = -11(8) + 5 = -88 + 5 = -83$

Plug in these values into the average rate of change formula:

$\frac{-83 - 5}{8 - 0} = \frac{-88}{8} = -11$

The average rate of change over this interval is -11.
