The sum of theee consecutive numbers is 90. what is the smallest of the three numbers?

29

Note that consecutive numbers have a difference of 1 between them.

let n be the smallest integer then the three integers can be expressed as

n, n + 1 , n + 2

the sum is then

n + n + 1 + n + 2 = 90

3n + 3 = 90

subtract 3 from both sides of the equation

3n = 90 - 3 = 87

divide both sides by 3

n = = 29

the three integers are 29, 30, 31 → the smallest is 29

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
