Which algebraic expression represent the phrase “ seven more than half of a number”?

The given expression “ seven more than half of a number” can be written mathematically as

Step-by-step explanation:

Given phrase “ seven more than half of a number”

We have to write the algebraic expression for the given phase.

Algebraic expression is the  way of writing an expression in mathematical form using mathematical operations and variables.

Consider the given phrase “ seven more than half of a number”

Let the number be N,

Then half of number is

and seven more means seven is added to this, the expresion becomes

Thus, the given expression “ seven more than half of a number” can be written mathematically as

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
