Janine's example of the origin is correct; however, not all x-coordinates that are <em />0 lie on the x-axis. For example, the coordinate (0,5) describes a point of a plane that is on the Y-axis only, but the x-coordinate is 0. In fact, the only x-coordinate that is 0 and on the x-axis is the origin.

Hope I could help! If the answer isn't correct, or it isn't the answer you are looking for, please let me know! Have a good one.

C. x³-4x²-16x+24.

In order to solve this problem we have to use the product of the polynomials where  each monomial of the first polynomial is multiplied by all the monomials that form the second polynomial. Afterwards, the similar monomials are added or subtracted.

Multiply the polynomials (x-6)(x²+2x-4)

Multiply eac monomial of the first polynomial by all the monimials of the second polynomial:

(x)(x²)+x(2x)-(x)(4) - (6)(x²) - (6)(2x) - (6)(-4)

x³+2x²-4x -6x²-12x+24

Ordering the similar monomials:

x³+(2x²-6x²)+(-4x - 12x)+24

Getting as result:

x³-4x²-16x+24

Andy is buying a car.
Minchanka [31]

The amount payed each month by Andy is £ 504

<u>Solution:</u>

Given that, Andy is buying a car.  

He negotiated a 7 percent decrease on a 6500 car.

Then, amount to be paid = 6500 – 7% of 6500  

\begin{array}{l}{\text { Amount to be paid }=6500 \times\left(1-\frac{7}{100}\right)} \\\\ {=6500 \times \frac{100-7}{100}=6500 \times \frac{93}{100}} \\\\ {\text { Amount to be paid }=65 \times 93=6045}\end{array}

He will pay the full balance in 12 equal monthly payments.

We have to calculate the amount paid each month

\begin{array}{l}{\text { monthly payment }=\frac{\text {total amount to be paid}}{12 \text { months }}} \\\\ {=\frac{6045}{12}=503.75}\end{array}

Hence, Andy has to pay £ 504 approximately each month.

Which expression is equivalent to 1/2 x + (-7) -2 q/4 x - (-2) ?
Marrrta [24]

Answer:

−1 /2 qx+ 1 /2 x-5

Step-by-step explanation:

Let's simplify step-by-step.

1 /2 x−7− 2q/ 4 x−(−2)

= 1 /2 x+−7+ (−1/2) qx+2

Combine Like Terms:

= 1 /2 x+−7+ (−1 /2 qx+2

=( −1 /2 qx)+( 1 /2 x)+(−7+2)

= −1 /2 qx+ 1 2x+−5

Answer:

= −1 /2 qx+ 1 /2 x-5

HOPE THIS HELPS!!!!!! :)
