I THINK it’s x = ±1/27 or ±8, again I’m not sure if I did the math correct but this is what I got
<span>x2 + 9x = 0
x(x+9) = 0
x=0
x+9 = 0; x = -9
answer is </span><span>a 0, -9</span>
Answer:
y = 12
Step-by-step explanation:
set up equation for 'y varies inversely with x': y = k/x
where 'k' is the constant of variation
8 = k/6
therefore, k = 48
value of y when x = 4: y = 48/4; therefore, y = 12
Answer:
x = 7
Step-by-step explanation:
3x - 17 = 25 - 3x
Get the x's on one side and the integers on the other
3x + 3x = 25 + 17
6x = 42
x = 7
The correct answer is d- one half x 2,175
Explanation: one half is 0.5 and 0.5 x 2,175 = 1087.5
