Use the Pythagorean Theorem to find the length of the side marked "x."
x^2 + (10 mi)^2 = (13 mi)^2. Thus, x^2 + 100 mi^2 = 169 mi^2.
Next, x^2= (169-100) mi^2, or x^2 = 69 mi^2. Find the positive square root of both sides of this equation. What is it?
Answer: see below
<u>Step-by-step explanation:</u>
The "point" on the inequality symbol points to the smaller number
- < is the "less than" inequality symbol
- > is the "greater than" inequality symbol
- = is the "equal" symbol

Answer:
y=5x-11
Step-by-step explanation:
parallel lines have the same slope 5
y-4=5(x-3)
y-4=5x-15
y=5x-15+4
y=5x-11
The answer is x=4 hope it helps
