Answer:
m=1/2 b =6
Step-by-step explanation:
m is the the gradient ( as in how much that line slant), so just use the formula
y2 - y1
------------
X2 - x1
For b, that the y-intercept,
Once u found m
Just choose any one of the coordinate they gave u (4,8) or(-6,3)
It will give u the same answers
Let's say u chose (4,8)
Theredore x = 4, y =8
y=mx + b
8= 1/2 x 4 + b
b= 6
The other one would give u the same answer
Answer:
The minimum number of Vinyl peel and stick floor tiles needed is 216 Tiles
Step-by-step explanation:
Here we have area size of Vinyl peel and stick floor tiles = 1 ft²
Size of floor of rectangular room = 12 ft × 14 ft = 168 ft²
Size of floor on rectangular hallway = 12 ft × 4 ft = 48 ft²
Total area of floor in rectangular room and rectangular hallway
= 168 ft² + 48 ft² = 216 ft²
Therefore number of Vinyl peel and stick floor tiles needed =
(Total area of floor in rectangular room and rectangular hallway)÷( Area size of Vinyl peel and stick floor tiles) = 216 ft²/(1 ft²) = 216
Therefore the minimum number of Vinyl peel and stick floor tiles needed = 216 Tiles.

Answer:
64.5%
Step-by-step explanation:
Initial amount N° = ?
Remaining amount after decay = N = ?
k = decay constant = 0.00012 
t = time = 3650 year
fraction remaining will be N/N°
From the decay equation, N = N°
N/N° = 
N/N° = 
N/N° = 
N/N° = 0.645 = 64.5%
