Answer:

<u>y = 1</u>

Step-by-step explanation:

<u>Given</u>

y ∝ x⁴

⇒ y = kx⁴

<u>Finding the proportionality constant, k</u>

y = 16 and x = 3
16 = k (6)⁴
16 = 1296k
k = 16/1296
k = 1/81

<u>Finding y</u>

y = 1/81 x (3)⁴
y = 1/81 x (81)
<u>y = 1</u>

Evan said that the difference between two negative numbers must be negative. Was he right? Use examples to illustrate your answe

vladimir1956 [14]

Yes he is right because if u have

-6 -(-4) u would multiply the 2 signs the - and the -4 and u would get +4

then ur equation becomes -6+4 = -2
