8 0

Answer:

The equation has infinity solutions

Step-by-step explanation:

we have

2(x+4)-1=2x+7

Applying distributive property left side

2x+8-1=2x+7

Combine like terms

2x+7=2x+7

The linear equation of the left side is equal to the linear equation of the right side

Both lines are identical

therefore

Is a consistent dependent system

The equation has infinity solutions

The rate of change in the function Y = 2X +5 is the rate of change of the function represented in the table
Alex17521 [72]

Answer:

The rate of change in the function Y = 2X +5 is <u>greater than</u> the rate of change of the function represented in the table

Step-by-step explanation:

The given function is

y = 2x + 5

For a linear function in the form y=mx +c, the rate of change is <em>m</em>.

The rate of change of this function is 2

We now determine the rate of change of the function represented in the table.

This is given by

\frac{change \: in \: y}{ change \: in \: x}

Using the corresponding values from the table, the rate of change is

\frac{6 - 4}{5 - 3}  =  \frac{2}{2}  = 1

Therefore the rate of change in the function Y = 2X +5 is greater than the rate of change of the function represented in the table
