If: y = 5x and y = 3 -x Then: 5x = 3 -x => 5x +x = 3 => 6x = 3 => x = 1/2 By substitution point of contact is at: (1/2, 5/2)

A division ladder is a method of finding the prime factors of a number. The number is divided by a prime number. That result is divided by another prime number. This continues until the result itself is a prime number. This result and the divisor from each step are the prime factors of the number. Here are the steps, but not quite the appearance of the division ladder. 108 ÷ 2 = 54 ÷ 2 = 27 ÷ 3 = 9 ÷ 3 = 3 The prime factors of 108 are 2, 2, 3, 3, and 3. Here is an example that better replicates the appearance of a division ladder that goes downward. 2 | 168 ...----- ..2 | 84 .....---- ..2 | 42 .....---- ..3 | 21 .....---- .........7 The prime factors of 168 are 2, 2, 2, 3, and 7.

The ladder is 7 foot up the wall if the ladder if the ladder is 3 ft away from wall.
A ladder should extend at least 3 feet beyond the surface it is accessing to ensure stability and prevent the ladder from slipping. This distance provides a secure anchor point for climbing up and down safely.

Before use, perform a thorough inspection and look for damage, bent rungs, grease on tread, defective feet, etc. Follow the labels on the ladder and the owner's manual. If you don't have the manual you can download a copy from the manufacturer's website. When you set the ladder, keep clear of electrical lines, Lean the ladder against the structure at a 4:1 (with your toes at the base of the ladder, your fingertips should touch the ladder with your arms extended). Check that the surface is firm and level. If the ground is soft, you can lay down a plywood square so the ladder won't sink. Check that the ladder won't kick out. If you are on hard pavement, ensure that the feet have the rubber tread down. Some ladders have "claws" on the feet that can be flipped to bite into the dirt. Extend the ladder so that it is between 3 and 4 feet above the top of the structure if you need to step off the ladder onto a roof. Secure the top of the ladder to the structure with a rope, strap or chain so the top won't slide. Maintain 3 points of contact while you climb. Always climb facing the ladder. Don't overload the ladder. Add your weight and what you are carrying up the ladder. Never put 2 people on the ladder at the same time.
