Answer:
a. The remaining length of the candle varies from <u>10 </u>inches to <u>5.5</u> inches
b. Remaining Length = 13 - b
Step-by-step explanation:
b.
The remaining (unburnt) length of the candle must be equal to the difference between total length of the candle and the burnt length of the candle. So, the expression for the remaining length can be written as:
Remaining Length = Total Length - Burnt Length
where,
Total length = 13 inch
Burnt Length = b
Therefore,
<u>Remaining Length = 13 - b</u>
<u></u>
b.
Now, we use the same expression for:
burned length = 3 inches
Therefore,
Remaining Length = 13 inches - 3 inches
Remaining Length = 10 inches
Now, for
burned length = 7.5 inches
Therefore,
Remaining Length = 13 inches - 7.5 inches
Remaining Length = 5.5 inches
Hence,
<u>The remaining length of the candle varies from 10 inches to 5.5 inches</u>
M= 6- -9 / 2- -1 = 6+9 / 2+1 = 15/3 = 5
y-6=5(x-2)
y-6=5x-10
y=5x-4
-9=5(-1)-4
-9=-5-4
-9=-9
6=5(2) -4
6=10-4
6=6
Step 1: find the slope using the formula m=y2-y1/x2-x1
Step 2: plug the slope and one point into the point-slope formula and solve to find the equation of the line in y=mx +b form.
Step 3: test both points to see if the equation works.
Answer:
11 years
Step-by-step explanation:
t=time
1700+50t=600+150t
The reason we have this equation is because they both have the same time and based on the initial numbers that they have equating the two will give you the exact year and number of students of both school.
For perpendicular lines, m1m2 = -1 or m2 = -1/m1.
Line y = 2x + 2 has a slope of 2, hence required slope is -1/2
Required equation is y - y1 = -1/2(x - x1)
y - 3 = -1/2(x - 6)
y - 3 = -1/2x + 3
y = -1/2 x + 3 + 3
y = -1/2 x + 6
Answer: 3/4 pound
Step-by-step explanation:
You do 12/16, which is simplified to 3/4.
