Answer:
D
Step-by-step explanation:
Replace R1 with 1 and R3 with 0 you have -2(1)+0 which equals 0 and that matches matrix II. Repeat the process with the other numbers in R1 and R3 and they all come out equal therefor the answer is D.
Answer:
t = 1.025c + 5.99
Step-by-step explanation:
Recall : general for of a linear equation is given by :
y = mx + c
Given the following :
Item cost = c
Shipping charge = $5.99
Tax on purchases = 2.5%
Total cost, t
t = c + tax + shipping cost
Tax on purchase : 2.5% * item cost ; 0.025c
Shipping = $5.99
Hence,
Total cost, t = c + 0.025c + 5.99
t = 1.025c + 5.99

Answer:
16
Step-by-step explanation:
ascending order:11,12,13,15,15,16,16,20,21,23,29,30,30
number of terms =13
median=[(n+1)/2] th term
=[(13+1)/2] th term
=[14/2] th tem
=7th term
=16
Hello! I would love to help!
Okay, we know that Raphel has to pay 3,000 dollars in a certain amount of months. Let's let "m" represent the amount of months it will take him.
Now, if we know that he saves 340 dollars a month, we can multiply the unknown amount of months, "m" by 340 to find how many will get 3000.
Here's our equation:
340m = 3000
Alright let's solve for m.
Divide both sides by 340.
340m/340= m
3000/340=8.824
So know we know m= 8.824, or exactly 8.824 months to save 3000 dollars.
However, it is really hard to count 8.824 parts of a month. Let's round it to the nearest whole, nine.
So, that means your answer is 9 months!
Hope this helped! Comment if you have questions!
