Answer:
13
Step-by-step explanation:
We need to use the Pythagorean Theorem to solve this problem:
, where a and b are the legs of the right triangle and c is the hypotenuse
In this case, we already know b (b = 84) and c (c = 85), so we need to solve for a:
Thus, a = y = 13.
Answer:
A.
Step-by-step explanation:
We have been given an equation of a line in point-slope form. We are asked to write our given equation in standard form.
Since we know that standard form of equation is: , where, a, b and c are constants.
Let us multiply both sides of our given equation by 2.
Let us add 6 to both sides of our equation.
Let us subtract x from both sides of our equation.
Multiply both sides of our equation by -1.
Rearranging our equation we will get,
Therefore, the standard form of our given equation is and option A is the correct choice.
