Answer: y + 5 = -3(x-3)
Step-by-step explanation:
Answer:

Step-by-step explanation:

Subtract the x terms:

Add 5 to both sides:


Multiply both sides by -1 and flip the inequality symbol:

Divide both sides by 5:


Answer:
Step-by-step explanation:
7+7x
That's a question about the Pythagorean Theorem.
We use the Pythagorean Theorem to find the value of one side in a right triangle.
This theorem says that:

- <em>a</em> is the hypotenuse (It's the opposite side the right angle).
- <em>b</em> and <em>c </em>are cathetus (They're the adjacent sides the right angle).
Okay, now, let's go to solve this problem! In our figure, we have two cathetus. Their values are 10 and 7 and we have to find the value of <em>x </em>(the hypotenuse). Let's change this information in that formula.

Therefore, the value of <em>x </em>is
.
I hope I've helped. :D

It is helpful to become familiar with the rules for secants of a circle.
The product of the numbers on the same chord is the same.
.. 2*x = 5*8
.. x = 20
