If m = (3x-1) and n = (3x+1),sjow that x² = mn+1 by 9​

See proof below

Step-by-step explanation:

Given that m = (3x-1) and n = (3x+1)

Taking the product

mn = (3x-1)(3x+1)

mn = 9x^2+3x-3x-1

mn = 9x^2 - 1

mn+1 = (9x^2-1+1)

mn+1 = 9x^2

Dividing both sides by 9

(mn+1)/9 = (9x^2)/9

(mn+1)/9 = x^2

Swap

x^2 = (mn+1)/9

This shows the required proof

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
