If f(x) = x2 -3, then what is f(-5)?
1 answer:
Answer:
22
Step-by-step explanation:
So if you have f(x) = x^2 - 3, then all you have to do is plug in x = -5 into the equation. This would be (-5)^2 - 3 = 25 - 3 = 22.
I hope that makes sense!

Your answer would be 13.2.
2500+150x=3000+125x. ---> 25x=500---> x=20. 20 months
I also worked it out but I got -5/3
2(6p-5) ≥ 3(p-8) -1
12p-10 ≥ 3p-24-1
12p-10 ≥ 3p-25
12p-3p ≥ -25+10
9p ≥ -15
-15/9
P ≥ -5/3
