When you solve the equation x + 1 = 2x for x, the solution is 1. 1) Square both sides of the equation, and verify that your solu

tion satisfies the new equation. 2) Show that −13 satisfies the new equation but not the original equation.

Answer:

(x + 1)² = (2x)²

(1 + 1)² = (2(1))²

2² = 2²

4 = 4

(-1 + 1)² = (2(-13))²

(-12)² = (-26)²

Not true

x = -13 satisfies neither

Situation 1: In Lakeville, Melinda’s television cable bill is a flat rate of $50 per month, plus $1.50 for every movie she rents
olchik [2.2K]

Answer:

situation 1 : flat rate of 50....1.50 per movie.....after 1 month her bill is 66.25

66.25 = 1.50x + 50

situation 2 : flat rate of 60....1.25 for every movie...

y = 1.25x + 60

both situations have a flat rate fee plus a charge for every movie. In situation 1, u can solve for x (the number of movies rented) because u know how much she was charged. However, in situation 2, without more information, u cannot solve this equation...what u would need to solve it would either be the number of movies rented or the total bill showing what she was charged. So basically, in situation 1, u are given more information then in situation 2.....enough information to be able to solve for the variable x...whereas, in situation 2, u are not given enough info to solve for a variable and get a numerical answer

Question : What is the constant of proportionality in the equation? ------------------------------------------------------------
valkas [14]

Answer:

1 1/2

Step-by-step explanation:

y = 1 1/2x​

The standard equation of direct variation is

y = kx,

where k = constant of proportionality.

Here you have

y = 1 1/2x​,

so 1 1/2 is k, the constant of proportionality.

Answer: 1 1/2

   Hopes this help please do me as brainlist and hit that thanks.
