How many whole numbers less than 100000 contain all digits 0, 2, 4, 6, 8?

(100,000 - 10,000) + 1 count for ( from 10,000 means 10,000 is included in it ) + 1 count for ( to 100,000 means 100,000 is also included in it )

= 90,000 + 1 + 1

= 90,002

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
