h = 2

$7 + 2h = 3 + 4h$

You must isolate the variable to solve using the order of operations, or PEMDAS.

$4 = 2h$

Subtract 3 from both sides of the equation, and subtract 2h from both sides of the equation.

$\frac{4}{2} = h$

Divide both sides of the equation by 2.

$h = 2$

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

serious [3.7K]

Answer:

The average rate of change is:

$\frac{13}{161}$

Step-by-step explanation:

The rational function given to us is;

$f(x)=\frac{3x+4}{2x+7}$

$f(0)=\frac{3(0)+4}{2(0)+7}$

$f(0)=\frac{4}{7}$

$f(8)=\frac{3(8)+4}{2(8)+7}$

$f(0)=\frac{28}{23}=1$

The average rate of change of this function from x=0 to x=8 is the slope of the secant line connecting:

(0,f(0)) and (8,f(8))

Average rate of change = $=\frac{f(8)-f(0)}{8-0}$

$=\frac{\frac{28}{23}-\frac{4}{7} }{8}$

$=\frac{13}{161}$

Analyze the diagram below and complete the instructions that follow. (7x - 3) (12x -7) Solve for x.

yarga [219]

Answer:

Step-by-step explanation:

(7x-3)(12x-7)

we are solving for x and we are multiplying.

we start with the x's 7x*12x= 84x

-3*-7=21

so now we have

84x+21=0

the 0 is a placer for answering the question

we minus 21 to both sides

84x=-21

now we divide

84/-21= -4

x=-4
