Answer:
x=-1, y=5. (-1, 5). The first number is -1 and the second number is 5.
Step-by-step explanation:
6x+2y=4
2x+4y=18
---------------
-2(6x+2y)=-2(4)
2x+4y=18
-------------------------
-12x-4y=-8
2x+4y=18
----------------
-10x=10
x=10/-10
x=-1
6(-1)+2y=4
-6+2y=4
2y=4-(-6)
2y=4+6
2y=10
y=10/2
y=5
Answer:
18.857
Step-by-step explanation:
Circumferenceof a circle = 2*22/7*r
C = 2* 22/7 * 3
C = 132/7
C = 18.857
Because of the "x-5" in the absolute value, the pieces will separate at x=5, because that's where x-5 = 0.
(This knocks out answer #1, 3, and 4)
To confirm option #2 is correct:
If you pick a number greater than 5, the absolute value doesn't do anything, so
if x > 5, a(x) = (x-5) + 1
If you pick a number less than 5, "x-5" is negative and the absolute value gives you the opposite of that value:
if x < 5, a(x) = - (x-5) +1
The answer is the second option.
Answer:
<u>Initial deposit = $ 60,241 (Rounding to the next whole dollar)</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Future Value = 100,000
Interest rate = 0.03
N = 22
2. Let's calculate the initial deposit for the sinking fund, this way:
Future Value = Initial deposit * (1 + i*N)
Replacing with the real values:
100,000 = Initial deposit * (1 + 0.03 * 22)
100,000 = 1.66 Initial deposit
Initial deposit = 100,000/1.66
<u>Initial deposit = $ 60,241 (Rounding to the next whole dollar)</u>
