A linear function models the height of a burning candle. Candle A comes out of the mold at 211 mm and is expected to be at 187 mm after 8 hours of burning. The model for Candle B is h=240-8t , where h is the height in millimeters and t is the time in hours. What are the initial values for each candle? What do the initial values for each candle tell you?
Use a pencil and paper. If the candles begin burning at the same time, can they ever be the same height? Explain.
The initial value for candle A is...... mm
Answer:
Step-by-step explanation:
h=196 and t=4 hours
196=220-xt, so -24=-xt
24=xt
24=4x
x=6
h=220-6t. units in mm
-------------
For B, 290-5(4)=290-20=270 mm, initial value of height.
what is the answer to 3 x - {-4 x} +12?
Answer:
7x+12
Step-by-step explanation:
since its neg, it take out { and } it no use.
if its like that, you add it.
so the equation: 3x+4x
that is 7x
+12 is after
so you do 7x+12
you can't simp it. So that is the answer

Use the hundredths grid to answer the question. A 10 by 10 grid is shown with 9 columns shaded and 1 row shaded with squares that overlap. Describe the decimal multiplication equation and product shown by the model. Include details of where each part of the equation is found on the model.
Answer:
A 9%
Step-by-step explanation:
There are 100 boxes and only 9 are shaded so a fraction of that would be 9/100 so if you convert that to a percentage it would be 9% of the boxes
so therefor 9% is you answer

Answer:
C.950
Step-by-step explanation
yes you would round down to 950
Answer:
D
Step-by-step explanation:
using front end estimation it would be d 1000
Front end estimation is the first number that you are rounding , it would either be 900 or 1000. its not rounding to the nearest 10 it's to the nearest hundred.
If it was to the nearest 10 it would be c 960. its not so its 1000

Is the relation in this table a function. Explain
Input: 2,4,6,8,10
output: 1,2,3,4,3
Answer:
Yes.
Step-by-step explanation:
This relation is a function because each input has one and only one output, i.e. 2 yields 1, 4 yields 2, 6 yields 3, 8 yields 4 and 10 has an output of 3. Therefore, it is a function.

50 - 20
= 30
Answer:
20 children got tickets.
Step-by-step explanation:
20/50 = 2/5

Graph the line y=3/2x-1
The graph of the equation is attached
How to make the table of values for the graphTo create a table of values for the equation y = (3/2)x - 1, you can choose different values for x and calculate the corresponding values for y. Here's an example table with x-values ranging from -2 to 2:
x y
-2 -4
-1 -2.5
0 -1
1 0.5
2 2
To find the corresponding y-values, substitute each x-value into the equation y = (3/2)x - 1 and solve for y.
For example,
when x = -2, you get y = (3/2)(-2) - 1 = -4.
Similarly, when x = -1, y = (3/2)(-1) - 1 = -2.5, and so on.
