Answer:

\left(x^4+3x^3-2x^2+5\right)+\left(2x^4-5x^3+4x-15\right)

= x^4+3x^3-2x^2+5+2x^4-5x^3+4x-15

=x^4+2x^4+3x^3-5x^3-2x^2+4x+5-15

=x^4+2x^4-2x^3-2x^2+4x+5-15

=3x^4-2x^3-2x^2+4x+5-15

=3x^4-2x^3-2x^2+4x-10

You accumulated a balance of $2,300 on your credit card that carries an interest rate of 17%. You can't afford to pay the $2,300
4vir4ik [10]

Answer:

$1,591.67

Step-by-step explanation:

The computation of the balance after 5 years is shown below:

Given that

Accumulated Balance on Credit Card = P = $2,300

r = Monthly interest amount = 17% ÷ 12 = 1.41666667%

M = Minimum payment = 2%

Now  

Balance on Credit Card after t year = P × (1+r) ×(1-M)

= $2,300 × (1+1.41666667%)^t × (1 - 2%)^t

= $2,300 × (0.993883337)^t

SO,

Balance on Credit Card after 5 years is

= $2,300 × (0.993883337)^60

= $2,300 × 0.692029437

= $1,591.66771

= $1,591.67

Which domain restrictions apply to this rational expression? x2 4x 4x2−4 select each correct answer.
rosijanka [135]

Because domain restrictions apply to this rational expression, x cannot be equal to {-2, 2}.

<h3>What is domain?</h3>

Domain restrictions are any points in the domain where the function will not have a value. This basically means that there is a point in the function where x will not work.

For the numerator, any value of x will suffice. We can have a value of 0 in the numerator, or a positive, negative, or decimal number.

However, the denominator cannot be equal to zero. This is due to the fact that a fraction bar represents division, and we cannot divide by zero.

Here,

x²-4=0

Add 4 to both sides:

x²-4+4 = 0+4

x² = 4

Take the square root of both sides:

√x² = √4

x = 2 or x = -2

The x cannot be equal to {-2, 2} as domain restrictions apply to this rational expression.
