Which of the following correctly isolates the constant for the polynomial: x2 – 12x + 27
Andru [333]

Answer:

x^2 - 12x = -27

Step-by-step explanation:

Here, we want to isolate the constant for the polynomial

To do this, we start by setting the expression to zero

Afterwards, we can bring the constant term over the equal to sign, giving a change in sign value

Mathematically, we have this as;

x^2 - 12x + 27 = 0

x^2 - 12x = -27

The price, e, of an entertainment system at extreme electronics is $220 less than twice the price, u, of the same system at ultr
MrMuchimi

Answer: The price of system at extreme electronics is $570 and the price of system at ultra electronics is $395.

Step-by-step explanation:

Let the price of the system at the ultra electronics be u

Let the price of the system at extreme electronics be e

According to question, we have

2u-e=220\\\\and\\\\e-u=175

Now, using the substitution method, we will solve the above system of equations.

e-u=175\\\\e=175+u

Now, put the value of u in the first equation :

2u-e=220\\\\2u-(175+u)=220\\\\2u-175-u=220\\\\u-175=220\\\\u=220+175\\\\u=\$395

Now, we put the value of u in the equation which is given by:

e=175+u\\\\e=175+395\\\\e=\$570

Hence, the price of system at extreme electronics is $570 and the price of system at ultra electronics is $395.
