Reika [66]

Answer:

The answer is 2

Step-by-step explanation:

Rate of change of function is given by :

\frac{(f(x_{2})-f(x_{1}))}{x_{2}-x_{1}}

For function y = 6,

rate of change =  

=\frac{(f(x_{2})-f(x_{1}))}{x_{2}-x_{1}}\\=\frac{6-6}{x_{2}-x_{1}}\\=0

because the function is independent of x.

For function y = 2·x + 7,

rate of change =

=\frac{(f(x_{2})-f(x_{1}))}{x_{2}-x_{1}}\\=\frac{2\cdot x_{2}+7-2\cdot x_{1}-7}{x_{2}-x_{1}}\\=\frac{2\cdot x_{2}-2\cdot x_{1}}{x_{2}-x_{1}}\\=\frac{2\cdot (x_{2}-x_{1})}{x_{2}-x_{1}}\\=2

So, the rate of change of 2 is greater than rate of change of function 1 by 2 - 0 = 2.

A Number is divided by 3. Then ,5 is added to the quotient snd the results is 8 what is the number
zheka24 [161]
Answer:

n=9

Explanation:

First, let's give a name to the number we are looking for and call it n.

So we can then write "A number is divided by 3" as n3

To add 5 to the quotient would then give us the expression n3+5

If this results in 8 we can finally write the equation we are trying to solve and solve the equation for n while keeping the equation balanced:

n3+5=8

n3+5−5=8−5

n3+0=3

n3=3

3⋅n3=3⋅3

1n=9

n=9
