There is a 1 in 11 chance of both marbles being blue
Answer:
Step-by-step explanation:
1)
y is 3 times more than x.
X=0 Y=0 3x0=0
X=1 Y=3
X=2 Y=6
X=3 Y=9
X=4 Y=12
Then just plot it as co-ordinates (x,y)
2)
Y is 1/4 of x. Divide by 4
X=0 Y=0
X=4 Y=1
X=8 Y=2
X=12 Y=3
X=16 Y=4
Then just plot it as co-ordinates (x,y)
The generic equation of the line is:

Where,
m: slope of the line
(T0, H0): ordered pair belonging to the line.
The slope of the line is:

Substituting values we have:

Rewriting:


Then, choosing an ordered pair we have:

Substituting values we have:

Rewriting the equation:

Then, for 8 hours we have:
Answer:
a linear equation to model the relationship between height H of the candle, and T time is:
the candle will be 12 inches after burning 8 hours
Answer:
b. x=2
Step-by-step explanation:
Step 1- Move the variable to one side.
12x-8= 3x+10
-3x -3x
9x-8= 10
Step 2- Add 8 to both sides.
9x-8= 10
+8 +8
9x= 18
Step 3- Divide to both sides.
<u>9x</u>= <u>18</u>
9 9
x= 2
