Answer:
h = -t+20
After 8 hours the candle will be 12 inches
Step-by-step explanation:
We have 2 points (time, inches)
(3,17) and (5,15)
We can find the slope
m = (y2-y1)/(x2-x1)
= (15-17)/(5-3)
= -2/2
= -1
We can use point slope form
y-y1 = m(x-x1)
Replace y with h and x with t
h-17 = -1 (t-3)
Distribute
h-17 = -t+3
Add 17 to each side
h-17+17 = -t+3+17
h = -t+20
After 8 hours
h = -t+20
h = -8+20
h= 12

Answer:
994
Step-by-step explanation:
PEMDAS
Parentheses: 8+2 = 10
Exponents: 10^3 = 1000
Subtraction = 1000-6
= 994
Answer:
x=5
Step-by-step explanation:
y= -x/2 + 5/2
substitute y=0
0= -x/2 + 5/2
solve the equation
x=5
Answer:
Step-by-step explanation:
hello :
the nth term of an arithmetic sequence is :
An =An+(n-p)d ....a common difference is : d
let : n=15 and p=1 d= 4 A15 =43
A15 = A1 + (15-1)(4)
43= A1 +56
A1= 43-56 = - 13
