Lila's office had already recycled 3 kilograms this year before starting the new recycling plan, and the new plan will have the office recycling 2 kilograms of paper each week. Write an equation that shows the relationship between the weeks x and the paper recycled y. Write your answer as an equation with y first, followed by an equals sign.

y = 2x + 3

Step-by-step explanation:

Based on the information provided we can use the values to write a proper algebraic equation like the following one ...

y = 2x + 3

The equation above states that the total number of paper that is recycled is equal to the 2 kilograms that are being recycled on a weekly basis plus the 3 kilograms that have already been recycled. This means that the value of y depends on the input given for the value of x which is the number of weeks that have passed.

step-by-step explanation:

equation

you are asked to write the equation

  expression = 0

using the given expression. when you do that, you have

  2x^2-2x-12 = 0

factoring

you can see that each of the coefficients is even, so a factor of 2 can be removed immediately.

  2(x^2 -x -6) = 0

if you multiply the binomials (x+a)(x+b), you get

  (x +a)(x +b) = x^2 +(a+b)x +ab

this tells you the coefficient of x is the sum of two factors of the constant term. here, that means -1 is the sum of two factors of -6. we want to know those factors so we can factor the trinomial.

  -6 = -1×6 = -2×3 = -3×2 = -6×1

the factor pair that sums to -1 is {-3, 2}, so our factorization is

  2(x -3)(x +2) = 0

solutions

the solutions to this equation are the values of x that make the product zero. a product is zero only when only of the factors of the product is zero. here, that means

  x - 3 = 0

  x = 3 . . . add 3 to both sides of the equation

or

  x +2 = 0

  x = -2 . . . add -2 to both sides of the equation

the solutions to the equation are x=3 or x=-2. both of these values of x satisfy the equation—they make it be true.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
