The systems will intersect at (1,-4), and i think the system has infinite solutions (not sure)
Answer:
<15,-21>
Step-by-step explanation:
u = <3, -1>
v = <-6, -6>
9u + 2v
9 <3, -1>+2 <-6, -6>
<27, -9> + <-12,-12>
<15,-21>
Answer:
-6
Step-by-step explanation:
2n can be the smallest integer, and 2n + 18 will be the largest integer.
The sum of this, divided by two, will result in the average/mean.
(2n + 2n + 18)/2 = 3
Multiply each side by 2:
(2n + 2n + 18)/2 ⋅ 2 = 3 ⋅ 2
2n + 2n + 18 = 6
Combine the like terms:
4n + 18 = 6
Subtract 18 from both sides:
4n + 18 - 18 = 6 - 18
4n = -12
Divide each side by 4:
4n/4 = -12/4
n = -3
Since we decided to go by 2n:
2n = 2(-3) = <u>-6</u>
Answer:
With compound interest, you earn interest on interest, thereby accumulating more money than if you were earning simple interest.
Step-by-step explanation:
40÷5= 8 You have to see how many time 5 can go into 40
1. see how many times 5 goes into 4 none so the first number is 0
2. then you see how many time 5 can go into 0 o times
3. so you have to see how many time you can count 5 into 40
(count by 5's) 5,10,15,20,25,30,35,40 that should be 8 times total!
