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

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
