Answer:
n = all real numbers
Step-by-step explanation:
7n+12=1/2(14n+24)
multiply each side by 2
2(7n+12)=2*1/2(14n+24)
distribute
14n+24 = 14n + 24
subtract 14n from each side
14n-14n+24 = 14n-14n + 24
24=24
this is always true
n = all real numbers
4,550 is the answer when you multiply the two numbers together.
Absolute value means the total distance from zero. So you get rid of any negative signs and then look at which number has the lowest value (which is the smallest number without any negative signs).
Wherever you see an x, replace it with -2,
So f(-2) = 2(-2^2) -15
= (2x4)-15
= -7
