Ah been on dis here site for 2 years and never heard about no medals.
total is 460 at most
x+y≤460
y is at least 4 times of x
y≥4x
ok, so realisitcally, yu can't donate negative amounts
only use first quadrant (use only positive x and y axises)
graph the line y=4x
shade to the right of the line
now graph the line y=-x+460 (yint at y=460)
y≤-x+460, so shade below that
see attached graphh
where the 2 graphs intersect is where the solution is (remember use positive x and y axises)
see other garph for graphed thing
so the equations to graph are
x+y≤460 and
y≥4x
Answer:
22'
Step-by-step explanation:
25^2=15^2+x^2 where x=tree height less the 2' from the top
x=20'
Add the 2' from wire connection to top of tree.
22'
Hello there,
I hope you and your family are staying safe and healthy during this winter season.
We need to use the Quadratic Formula*
,
Thus, given the problem:
So now we just need to plug them in the Quadratic Formula*
,
As you can see, it is a mess right now. Therefore, we need to simplify it
,
Now that's get us to the final solution:
,
It is my pleasure to help students like you! If you have additional questions, please let me know.
Take care!
