﻿Immediate and Inverse Variations

Slide 2

When we discuss an immediate variety, we are discussing a relationship where as x expands, y increments or reductions at a CONSTANT RATE . Coordinate Variation

Slide 3

Direct Variation Direct variety utilizes the accompanying equation:

Slide 4

illustration: if y fluctuates straightforwardly as x and y = 10 as x = 2.4, discover x when y =15. what x and y go together? Coordinate Variation

Slide 5

If y differs specifically as x and y = 10 discover x when y =15. y = 10, x = 2.4 make these y 1 and x 1 y = 15, and x = ? make these y 2 and x 2 Direct Variation

Slide 6

if y fluctuates straightforwardly as x and y = 10 as x = 2.4, discover x when y =15 Direct Variation

Slide 7

How would we understand this? Cross duplicate and set equivalent. Coordinate Variation

Slide 8

We get: 10x = 36 Solve for x by plunging both sides by 10. We get x = 3.6 Direct Variation

Slide 9

Let\'s do another. On the off chance that y shifts straightforwardly with x and y = 12 when x = 2, discover y when x = 8. Set up your condition. Coordinate Variation

Slide 10

If y differs specifically with x and y = 12 when x = 2, discover y when x = 8. Coordinate Variation

Slide 11

Cross duplicate: 96 = 2y Solve for y. 48 = y. Coordinate Variation

Slide 12

Inverse is fundamentally the same as immediate, yet in a converse relationship as one esteem goes up , alternate goes down . There is not really a steady rate. Reverse Variation

Slide 13

With Direct variety we Divide our x\'s and y\'s. In Inverse variety we will Multiply them. x 1 y 1 = x 2 y 2 Inverse Variation

Slide 14

If y changes conversely with x and y = 12 when x = 2, discover y when x = 8. x 1 y 1 = x 2 y 2 2(12) = 8y 24 = 8y y = 3 Inverse Variation

Slide 15

If y differs contrarily as x and x = 18 when y = 6, discover y when x = 8. 18(6) = 8y 108 = 8y y = 13.5 Inverse Variation
