4x + 3
Hope this helped :)
Answer:
greater than 2
less than 28
Step-by-step explanation:
The sum of the lengths of the two shortest sides must be more than the length of the longest side. If x is the shortest side, ...
... x + 13 > 15
... x > 2
If x is the longest side, ...
... 13 +15 > x
... x < 28
Then the allowed range for the third side is ...
... 2 < x < 28
Polygon with different measurements
Answer:
-3
Step-by-step explanation:
-15/5 is equivalent to -3, so wherever on your number line "-3" is, circle that
Find the inverse of f(x)=2x-3.
1) replace "f(x)" with "y." Then y=2x-3.
2) interchange x and y. Then x=2y-3. x+3
3) solve this result for y. Then 2y=x+3, or y=----------------
2
-1 -1 x+3
4) replace y with f (x): f (x) = ---------
2
This is the procedure, with the answer given.
