Answer:
Step-by-step explanation:
The slope is -3
You can now substitute (1,-5) for x and y
-5= -3+b
b=-2
So in slope intercept form the answer is y=-3x-2
In point slope form the answer is 3x+y=-2
Complete question :
Solve the compound interest problem. $3425 is invested at %7.5 compounded monthly for 2 years. a. Find the overall amount. b. Find the compound interest.
Answer:
$3977.425 ; $552.425
Step-by-step explanation:
Given that:
Principal (P) = $3425
Rate (r) = 7.5% = 0.075
Time(t) = 2 years
A = p(1 + r/n)^nt
r = rate
n = number of times compounded per year
t = time in years
A = final amount
A = 3425(1 + 0.075/12)^12*2
A = 3425(1 + 0.00625)^24
A = 3425(1.00625)^24
A = 3425(1.1612920)
A = $3977.4251
Hence, overall amount = $3977.425
Compound interest = $(3977.425 - 3425) = $552.425
Answer:
Noah
Step-by-step explanation:
For Andre you would divide 208 words by 4 minutes getting 52 words per minute. Then, for Noah divide 342 words by 6 minutes getting 57 words per minute. Noah types faster because he can type more words per minute.
Answer:
11
Step-by-step explanation:
It is given that:
r = 14 & s = 8
Plug in the corresponding numbers to the corresponding variables:
(3/7)(14) + (5/8)(8)
Solve. Remember to simplify. Do multiplication & division first, then add:
(3/7)(14) + (5/8)(8)
(3 * 14)/7 + (5 * 8)/8
(3 * 2) + 5
(6) + 5
11
11 is your answer.
