Answer: f(x) = ∛(x+4)^2=8 + 3 = 11
4x5=20-9=11
Step-by-step explanation:
When adding/subtracting fractions you need a common denominator, but you already have one, which is x-3. So in general:
a/c-b/c=(a-b)/c so you just have:
(2x-6)/(x-3) now if you factor 2 from the numerator
2(x-3)/(x-3) the (x-3)s cancel out leaving
2
However! Note that division by zero is undefined, so x cannot equal 3. (because both original fractions had denominators of x-3)
What this all means is that that expression will equal 2 for all real values of x other than 3.
To how many sig figs or decimal places? Could use 1735 if rounded to 2 significant figures (2sf)
Answer:
3 1/5 ft
Step-by-step explanation:
We can set up a proportion:
, where x is how long the pants are in real life
Cross multiply:
x = (2 2/7) * (1 2/5)
It's easier if we have improper fractions, so convert the mixed numbers into improper fractions:
2 2/7 = 16/7
1 2/5 = 7/5
Now, put these back in:
x = (16/7) * (7/5) = 16/5 = 3 1/5
Thus, in real life, the pants would be 3 1/5 ft long.
Hope this helps!
I would say D) Infinitely many.
The question is slightly confusing but what I can tell is there are at least 3 points on the graph that are touched so it can't be asking about that since we have answers like 0, 1 and 2.
So next, we can look at the slopes aka how far the lines reach and cross. They seem to keep going on and on without stopping at any visible point on the graph. So you can say there are infinitely many solutions with any real number.
