Sally's goal is to collect between 900 and 1,000 seashells. Write and solve a compound inequality to determine the range of weeks during which Sally can

meet her goal. Show your work.

900 ≤ x ≤ 1000

Step-by-step explanation:

Given

Minimum = 900

Maximum = 1000

Required

Write and solve a compound inequality

Represent the number of seashells with x.

To solve this, we first consider the minimum.

The relationship between x and the minimum is:

x ≥ minimum

This gives

x ≥ 900

Then, we consider the maximum.

This is represented as:

x ≤ maximum

x ≤ 1000

The two inequalities are:

x ≥ 900 and x ≤ 1000

This can be rewritten as:

900 ≤ x and x ≤ 1000

Combine both:

900 ≤ x ≤ 1000

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.

answer: 140

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people
