Answer:

x = 4\sqrt{3} in

Step-by-step explanation:

Given a tangent and a secant to the circle from an external point, then

The square of the tangent is equal to the product of the secant's external part and the entire secant, that is

x² = 4(4 + 8) = 4 × 12 = 48 ( take the square root of both sides )

x = \sqrt{48} = \sqrt{16(3)} = \sqrt{16} × \sqrt{3} = 4\sqrt{3} ← exact value

Melanie saves $20 every month in her savings account. She
OLga [1]

Let x represent the amount of months she has been saving for.

20x - 60 = 280

Solve for x.

20x - 60 = 280

~Add 60 to both sides

20x - 60 + 60 = 280 + 60

~Simplify

20x = 340

~Divide 20 to both sides

20x/20 = 340/20

~Simplify

x = 17

Therefore, Melanie has saved for 17 months.

Best of Luck!

Help? I'm not exactly sure how to do this :/
uranmaximum [27]
What you do is plug the z value (first column) into the formula (second column), and solve for y. For instance, the first one would be y = -1-2, or -3. The x would be the x in the ordered pair, and the final ordered pair would be (-1,-3). Make sense?
