Answer:
Amelia will invest $2800 and $6200 in the two accounts.
Step-by-step explanation:
Let us assume that Amelia has invested $x and $y in the two accounts respectively.
So, x + y = 9000 ...... (1)
Again the total interest is $580 for investing $x in 3% annual interest and $y in 8% annual interest.
Hence,
⇒ 3x + 8y = 58000 ..... (2)
Now, solving equations (1) and (2) we get,
5y = 58000 - ( 9000 × 3 )
⇒ 5y = 31000
⇒ y = 6200
Hence, from equation (1) , x = 9000 - 6200 = 2800
Therefore, Amelia will invest $2800 and $6200 in the two accounts. (Answer)

Answer:
y= 34x- 2 +5 (C)
Step-by-step explanation:
The equation: y = 27x-54 +5
We are to determine an equivalent equation of the form y=avx -h+k from the options given.
From the above, av = two digit coefficient of x. Hence av is constant.
h and k are also constant.
Let's check out the option to find the equation that is in the form y=avx-h+k
a) y=-273x + 2+5
In this equation, the coefficient of x is a 3-digit number. The option is wrong.
b) y=-3x+2 +5
In this equation, the coefficient of x is a 1-digit number. The option is wrong.
c) y=34x -2 +5
In this equation, the coefficient of x is a 2-digit number.
av = 34, h= 2 and k = 5
This equation is in the form of y=avx -h+k
The option is correct.
d) y=273/x-2 +5
This equation is not in the form of y=avx -h+k
The option is wrong.
