30% Is the answer ........
Answer:
<em>x = 12</em>
Solve for x:
<em>Using Pythagorean Theorem </em>
a^2 + b^2 = c^2
a = 9
c = 15
b = x
9^2 + x^2 = 15^2
81 + x^2 = 225
x^2 = 144 | sqrt
x = 12
-4x^2-5(x+3)+x^2 :
-4x^2-5x-15+x^2
-3x^2- 5x -15
Table C represents a function
This is because each x value has only one y value. For the other tables, the x values of 4, 9, and 8 have 2 different y values.
Are there choices?
