Step-by-step explanation:
Here,
y= 2x
and x € (1,2,3)
now,
when x=1 , when x=2 , when x= 3
y=2x y= 2x y=2x
= 2×1 = 2×2 = 2×3
= 2 = 4 = 6
Therefore, y = (2,3,6)
Answer:
5,477.63
Step-by-step explanation:
First, convert R percent to r a decimal
r = R/100
r = 6%/100
r = 0.06 per year,
Then, solve our equation for P
P = A / (1 + r/n)nt
P = 5,500.00 / (1 + 0.06/4)(4)(0.068448)
P = 5,500.00 / (1 + 0.015)(0.273792)
P = $ 5,477.63
Summary:
The principal investment required to get
a total amount of $ 5,500.00
from compound interest at a rate of 6% per year
compounded 4 times per year
over 0.068448 years
is $ 5,477.63.

Step-by-step explanation:
Answer:
A(3,-1) and B( -2,1)
Step-by-step explanation:
2x+5y=1. , or. y=(1–2x)/5………….(1)
x^2+5xy-4y^2+10=0…………………..(2)
Putting y=(1–2x)/5 from eqn. (1)
x^2+5x.(1–2x)/5–4/25.(1–2x)^2 +10=0
or. 25x^2+25x.(1–2x)-4.(1+4x^2–4x)+250 = 0
or. 25x^2+25x-50x^2–4–16x^2+16x+250=0
or. 41x^2–41x-246=0
or x^2– x - 6=0
or. (x-3).(x+2)=0
=> x= 3 or -2
But y=(1–2x)/5
=> y= (1–6)/5 or. (1+4)/5
hence, y= -1. or. 1
