D
Step-by-step explanation:
If we isolate the variable in each given compound inequality, we can quickly realize that D is correct.

x is less than or equal to four (solid point on 4 with line going left), but greater than -1 (open point going right).
Signs with 'or equal to' have solid points, and signs without are not solid.
I hope this helps!
Janine = J = 15
Leah = L = ?
L = J + 6
L = 15 + 6
L = 21
So Leah spent $21
Answer: FIRST OPTION
Step-by-step explanation:
To solve this problem you must apply the Intersecting Secant-Tangent Theorem. By definition, when a secant line and a tangent lline and a secant segment are drawn to a circle from an exterior point:

The total measure of the secant shown is:

If the radius is 7, then the diameter is:

Therefore:

You also know that:

Keeping the above on mind, you can substitute values and solve for x:
