The sum of a number and five is seven. find the number.

the number is

x = 2

Step-by-step explanation:

5 + x = 7

5 + x - 5 = 7 - 5

x = 7 - 5

x = 2

f(x) has no x-term.

Option 2.

Explanation:

Linear function are those whose graph is a straight line. A straight capacity has the accompanying structure. y = f(x) = a + bx. A direct capacity has one autonomous variable and one ward variable. The autonomous variable is x and the reliant variable is y.

A linear function is an arithmetical condition wherein each term is either a consistent or the result of a steady and (the principal intensity of) a solitary variable. A capacity is a connection with the property that each info is identified with precisely one yield. A connection is a lot of requested sets.
