L(t)=9-0.5t
t=time in hours,
L(t)=length of candle at time t
(A) substitute t=1,2,3,4,5,6 respectively to get
(1,8.5)
(2,8)
(3,7.5)
(4,7)
(5,6.5)
(6,6)
(B) it is a function because none of the x-values duplicate, (nor the y-values).
(C) If the rate changes to 0.45 "/hr, the relation is still linear.
All linear function with finite slope are functions.
Answer:
3t +2
Step-by-step explanation:
In order to combine the like terms, you look at the constants and the variables. A variable has a letter in it. When looking at this expression, you find that there are two variables, 4t and -t. You then simplify these variables, getting 3t because it is 4t - t. Now, there is a two left, and since that ISN'T a variable, and is a constant, we can't do anything with it because we cannot combine it with anything else in the expression. Your guess was partially right ;)
Hope this helped!
If the selling price is marked up by 25 percent, the new price will be $10.
8 * 1.25 = 10
If the selling price is marked up by 70 percent, the new price will be $13.60.
8 * 1.70 = 13.6
If the selling price is marked up by 75 percent, the new price will be $14.
8 * 1.75 = 14
Answer:
4b³c⁴ + 2b⁴c³
Step-by-step explanation:
5b⁴c³ and 3b⁴c³ have the same variables. Therefore, they are like terms.
4b³c⁴ + 5b⁴c³ - 3b⁴c³
4b³c⁴ + 2b⁴c³
