Y=1\2x.
hopes this helps you
Answer:
the first one
Step-by-step explanation:
i did the test and got it right
=> The answer is <u>2</u><u>.</u>
F(X) = x^4 +64x^2
x^4 +64x^2 = x^2(x^2 +64)

<span>the sum of the first and three times the second is 54.
x + 3y = 54
3y = 54 - x
y= 54 /3 - x / 3 = 18 -x /3
</span>xy = x (18 -x /3) = 18x - x^2 / 3 = - 1/3 x ^ 2 + 18 x
<span>
</span><span>since a<0, it is concave downward, and the vertex is the maximum value. That vertex occurs at x= - b /2a = (-18) / (-2/3) = 12
</span>
<span>The first number is x=12.
The second is y = </span><span>18 -x /3 = 18- 12/ 3 = 18 - 4 = 14 </span>
