Let n be the middle number of three consecutive even integers. write an expression for the sum of these integers.

The expression for the sum of these integers is 3n

Let the first number be n-2

Let the middle number be n

Let the third number be n+2

The expression for the sum of these integers will be:

=(n - 2) + n + (n + 2)

= n - 2 + n + n + 2

Collect like terms

= 3n

The expression for the sum of these integers is 3n

step-by-step explanation:

shell's the art director at her local community center. she paid $10 and for each child that attends she earns $4.

for each child she ears $4 that is the slope m = 4

she paid $10, that is the initial amount paid. so 10 is the y intercept b

m =4   and b = 10

y intercept is 10 so the point is (0,10)

we start graph from y intercept (0,10)

slope = 4 . we know slope = rise / run

slope = 4   or 4/1   are same

rise = 4   and run = 1

for rise we move 4 units up and for run we move 1 unit to the right

the graph is attached below

x axis is the number of child she attends

y axis is the amount   she earns
