Which equation corresponds to the statement, to more than a number equivalent to Y

Mariana [72]

Answer:

English statement 'two more than a number equivalent to Y' can be algebraically represented as:

y = x + 2

Step-by-step explanation:

Two more than a number means we need to add 2 to a number.

Let suppose the number be = x

Two more than the number 'x' = x+2

As it is stated that two more than a number equivalent to Y.

Equivalent means something is equal to the given expression.

Mathematically, the 'equivalent' is represented by the symbol '='.

Thus, the English statement 'two more than a number equivalent to Y' can be algebraically represented as:

y = x + 2

Enter the difference between the rates of change for these two functions.

Alchen [17]

Answer:

.

Step-by-step explanation:

Graph :

Choose any two points. (0 , 2) and (-1 , -2)

Rate of change = Change in y ÷ Change in x

$= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\= \frac{-2 - 2}{-1 - 0}\\\\= \frac{-4}{-1}\\\\= 4$

Table:

Rate of change = $\frac{-2-[-6]}{2-0}$

$= \frac{-2+6}{2}\\\\= \frac{4}{2}\\\\= 2$
