Answer:
A. Y = 2/3x
Step-by-step explanation:
Each Y is 1/3 less than X
Answer: (D) 9
<u>Step-by-step explanation:</u>
This is an isosceles triangle. Since the legs are congruent, then the base angles are congruent.
9x + 3 = 84
<u> - 3 </u> <u> -3 </u>
9x = 81
<u>÷9 </u> <u>÷9 </u>
x = 9
The ordered pair is not a solution to the equation

Answer:
14.14
Step-by-step explanation:
The diagonal of a square is √2 times the side length.
AC = AB×√2
AC = 10√2 ≈ 14.14
_____
The diagonal of a square is the hypotenuse of an isosceles right triangle. If the sides of that are s and the diagonal is d, the Pythagorean theorem tells us ...
d² = s² + s²
d² = 2s²
d = (√2)(√s²) = s√2
This relation holds for <em>any isosceles right triangle</em>, not just for the diagonal of this square. It is useful to remember.
