7x+12+6x-2=-4
7x-6x=-4-12+2
13x=-14
x=-14 divide 13
x=-14 over 13 put 14 over 13 in a fraction
After I read the equation, I remembered that anything to the power of 1 is itself. so f(x)=2-9
2-9= -7
therefore, f(x)= -7
if x=1, then the f(x) must be Y
<u><em>therefore, your answer should be y= -7</em></u>
Answer:
36 years old (jim)
Step-by-step explanation:
looks like a good ol' word problem!
first, if you don't know what to do, always assign variables
Jim's age: x+9
June's age: x
Alex's age: x-8
we know the sum of their ages which is 82
so, x+9+x+x-8=82
simplify
3x+1=82
3x=81
x=27, but we're not done yet
Now we know x
jim: 36
june: 27
Alex: 21
so the oldest is jim at 36
