Answer:
p70 is the point of the bottom lines
Answer: x = t, y = 2t/3 + 2
Step-by-step explanation:
You want to write both x and y in terms of t
so if you rearrange 4x - 6y = -12 you get
-6y = -4x - 12
6y = 4x + 12
y = 2x/3 + 2
set x = t
and y = 2t/3 + 2
and that's it!
another one you could do is
x = t/2
y = t/3 + 2
or even
x = 3t/2
y = t + 2
i like this one the most because it looks more elegant
Answer:
t = 5
Step-by-step explanation:
20t + 5 + 15t = 180
35t + 5 = 180
35t = 175
t = 5

Answer:
Table C
If the bacteria population triples every hour, it must multiply by three each time.
Table C fits this pattern
y | 1 | 3 | 9 | 27 | 81 | 243 | 729
1×3=3, 3×3=9, 9×3=27 etc.
Investing $1000, compounding the interest once in a year will yield a final Amount of $1,935.28.
Given data
Principal = $1000
Rate = 4.5%
Time = 15 years
Calculation Steps:
First, convert R as a percent to r as a decimal
r = R/100
r = 4.5/100
r = 0.045 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 1,000.00(1 + 0.045/1)^(1)(15)
A = 1,000.00(1 + 0.045)^(15)
A = $1,935.28
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $1,000.00 at a rate of 4.5% per year compounded 1 times per year over 15 years is $1,935.28.
