Answer:
part a- y= x × 100
Step-by-step explanation:
x is the amount of bars there is and if 1 bar = 100 calories then you would times the amount of bars by 100.
haha i just saw someone with the exact same question.
Answer:
yes
Step-by-step explanation:
because of math,
First of all
x^2 +10x - 18
use
x = (-b plus or minus (<span>√<span></span></span>(b^2-4ac)))/2a
you will get
(x+5−(<span>√<span><span><span>43)</span></span><span></span></span></span>)(x+5+(<span>√<span><span><span>43</span></span><span>))</span></span></span>
Answer:
- 2 trees ($200 from either service)
- c=100+50t
- c=80+60t
Step-by-step explanation:
It can work well to solve problems like this by considering how many times the difference in per-tree costs it takes to make up the difference in one-time costs.
Here the difference of one-time costs is $20, and the difference in per-tree costs is $10, so it takes the pruning of 2 trees for the per-tree cost difference to equal the one-time cost difference (2×10 = 20).
___
The cost equations are ...
cost = (one-time cost) + (per tree cost) × (number of trees)
c = 100 + 50t . . . . . company A
c = 80 + 60t . . . . . . company B
_____
If you use these equations to solve the problem, you want to find t such that the two costs are equal:
100 +50t = 80 +60t
(100 -80) = t(60 -50) . . . . . . . subtract 80+50t, factor out t
(100 -80)/(60 -50) = t . . . . . . . looks a lot like the verbal description above
The difference in fixed price divided by the difference in per-tree cost) is the number of trees required to make costs equal.
