Answer:
12x +12y = 7
Step-by-step explanation:
The 2-point form of the equation for a line is useful.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (1/3 -1/4)/(1/4 -1/3)(x -1/3) +1/4
y = (1/12)/(-1/12)(x -1/3) +1/4)
y = -x +1/3 +1/4
Add x and multiply by 12.
x +y = 1/3 +1/4
12x +12y = 4 +3
12x +12y = 7
She invested part in an account earning at 5% annual interest = $36400
Explanation:
Given:
Mardi received an inheritance = $94,000.
She invested part in an account earning at 5% annual interest
deposited the remainder in tax-free bonds earning 3% annual interest.
Her total annual income from the investments was $3548
To Find:
The amount invested at 5% to the nearest dollar.
Solution:
Let the amount mardi invested in an account earning at 5% be x
Then the remaining amount she deposited in tax-free bonds earning at 3% annual interest is 94000 - x
So according to question
x=36400
