What is the average rate of change of the function over the interval x = 0 to x = 6? f(x) = (2x - 1) / (3x + 5)
Sedaia [141]

Answer:

The average rate of change of the function over the interval x = 0 to x = 6 is \frac{34}{195}.

Step-by-step explanation:

Geometrically speaking, the average rate of change (r) of the function over a given interval is determined by equation of secant line, that is:

r = \frac{f(b)-f(a)}{b-a} (1)

Where:

a, b - Lower and upper bounds.

f(a), f(b) - Function evaluated at lower and upper bounds.

If we know that f(x) = \frac{2\cdot x -1 }{3\cdot x + 5}, a = 0 and b = 6, then the average rate of change of the function over the interval is:

f(a) = \frac{2\cdot (0)-1}{3\cdot (0) +5}

f(a) = -\frac{1}{5}

f(b) = \frac{2\cdot (6)-1}{3\cdot (6)+5}

f(b) = \frac{11}{13}

r = \frac{\frac{11}{13}-\left(-\frac{1}{5} \right) }{6-0}

r = \frac{34}{195}

The average rate of change of the function over the interval x = 0 to x = 6 is \frac{34}{195}.

Which transformation shows a relfection of DEF?
AfilCa [17]

Answer:

The middle option.

Step-by-step explanation:

This is because the points on each triangle are equidistant from the imaginary line in between the two triangles.  It isn't the first option because that is a rotation, and it isn't the third right option because that is a translation.

Express x in terms of y! Find the value of x when y =5<br>2(x - 3)/y =5​
m_a_m_a [10]

Hey there!

2(x - 3) / y = 5

2(x - 3) / 5 = 5

2(x) + 2(-3) / 5 = 5

(2x - 6) 5 = 5

MULTPLY 5 to BOTH SIDES

(2x - 6)/5 * 5 = 5 * 5

SIMPLIFY IT!
2x - 6 = 5 * 5

2x - 6 = 25

ADD 6 to BOTH SIDES

2x - 6 + 6 = 25 + 6

SIMPLIFY IT!
2x = 25 + 6

2x = 31

DIVIDE 2 to BOTH SIDES

2x/2 = 31/2

SIMPLIFY IT!

x = 31/2

x = 15 1/2


Therefore, the answer should be:

x = 15 1/2


Good luck on your assignment & enjoy your day!
