Erin writes the expression “ $6$ less than double a number.”

Write an algebraic expression that is equivalent to Erin’s expression.
Write a second algebraic expression that is different from, but equivalent to, your first expression.
Respond in the space provided.

For this case we must algebraically rewrite the given expression. So:

x: It is the variable that represents an unknown number

"double a number" is represented as:

"6 less than double a number" is represented as:

So, the final expression is:

If we want to rewrite the expression in an equivalent way, we take common factor 2:

Asnwer:

Equivalent expression:

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
