Answer:
f(-2) = -4
Step-by-step explanation:
f(x) = x^3-2x,
Let x = -2
f(-2) = (-2)^3 - 2(-2)
= -8 +4
= -4
Answer:
if you're still looking at it is not the problem for you have the time of me and the other day that we will not for sure if I
Let’s do 3x - 8 ≤ 23 first.
You need to rearrange this so that x is on its own.
+8 to both sides
3x ≤ 31
/3 on both sides
x ≤ 31/3
Then the second, -4x + 26 ≥ 6
-26 from both sides
-4x ≥ -20
/-4 on both sides
x ≥ 5
So x is greater than or equal to 5, which can also be written as 5 ≤ x
And for the first one, x is less than or equal to 31/3, which can still be written as x ≤ 31/3, so your final answer is:
5 ≤ x ≤ 31/3
Chris' still water speed is 3mph, and the current's is 1.5mph... well, when Chris is going upstream, he's really not going at 3mph, since is not still water, the water is actually running, so, he's going " 3 - 1.5 " mph.
now, recall you d = rt, distance = rate * time
