Answer:
Step-by-step explanation:
let x be one part of the money invested.
let y be the other part of the money invested.
x *(10/100) -- amount on 10% of interest per annum
y*(7/100)- amount invested on 7% of interest per annum
x *(10/100) + y*(7/100) =1400
on simplifying it
10x +7y =140000 --(1)
On interchanging the interest rate on x amount and y amount of the investor
x *(7/100) + y*(10/100) =1490
7x +10y =149000-(2)
on solving equation (1) and (2) we get
70x +49y =980000
70x + 100y =1490000
-51y= -510000
y=10000
and x=7000
So our total amount invested is 17000
Answer:
y = -2x/3 + 6
Step-by-step explanation:
y = mx+b
m = y2-y1/x2-x1
m = 2 - 6/6 - 0
m= -4/6 = -2/3
b = y-intercept = 6
