Answer:
B) perpendicular
Step-by-step explanation:
i graphed them
The annual interest that can be earned through investment of an amount at a simple interest can be calculated through the equation,
I = P x (i)
where I is interest, P is the principal amount, and i is the decimal equivalent of the interest.
Let x be the amount deposited with 3.5% interest. With this representation, the amount deposited with 5.5% is 5800 - x.
The linear equation that would represent the given scenario is,
x(0.035) + (5800 - x)(0.055) = 283
Simplifying the equation,
0.035x + 319 - 0.055x = 283
Combining like terms,
-0.02x = -36
Dividing by -0.02,
x = 1800
$5800 - x = $5800 - $1800 = y
y = $4000
Hence, the value that should be deposited to the 5.5% is $40000.
Answer:
5/9 & -10/3
Step-by-step explanation:
Set each to 0 and solve:
9x-5 = 0
9x=5
x=5/9
6x+20=0
6x=-20
x=-20/6
x= -10/3 or -3 1/3
