Let M = marker cost
Let P = pencil cost
3 markers and 2 pencils cost 1.80 ==> 3M + 2P = 1.80
4 markers and 6 pencils cost 2.90 ==> 4M + 6P = 2.90
Multiply the first equation by (-3) and add it to the second equation
-9M - 6P = -5.40
4M + 6P = 2.90
-5M = -2.50
M = 0.50
Plug this value for M into the 1st equation and solve for P
3*(0.50) + 2P = 1.80
1.50 + 2P = 1.80
2P = 0.30
P = 0.15
So a marker costs 50 cents and a pencil costs 15 cents
The correct answer for this question is this one:
<span>- The initial value of the function is.
- The function shows exponential decay.
- The function is a stretch of the function f(x) = .
- One point on the graph is (3, 0).</span>
Hope this helps answer your question and have a nice day ahead.
Answer:
Step-by-step explanation:
Use the formula for the volume of a cylinder 
so then you plug in the values to get
5p+2=4p-1
1p+2=-1
1p=-3
p=-3
Alright, so [-2.99] is -2.99, and [2.99] is 2.99, so -2.99+2.99=0
