$269.15 discount 499.85 sales price

Step-by-step explanation:

If the price is $769 it's off 35% you turn the percent into a decimal which is .35 then you multiply it by the price of $769. You then get $269.15 for the discount price and then you subtract the regular price $769 from the discount price which is $269.15. So you get $499.85 as your answer

Given:

$m=0.56x-0.25$

$n=0.20x-0.03$

To find:

The sum of m and n.

Solution:

We have,

$m=0.56x-0.25$

$n=0.20x-0.03$

The sum of m and n is:

$m+n=(0.56x-0.25)+(0.20x-0.03)$

Combining the like terms, we get

$m+n=(0.56x+0.20x)+(-0.25-0.03)$

$m+n=(0.76x)+(-0.28)$

$m+n=0.76x-0.28$

Therefore, the sum of m and n is $m+n=0.76x-0.28$ .

Which function is a quadratic function? u(x) = –x 3x2 – 8 v(x) = 2x2 8x3 9x y(x) = x2 3x5 4 z(x) = 7x2 2x3 – 3.

Komok [63]

The function $u(x)=-x+3x^{2} -8$ is a quadratic function due to the highest exponent being 2.

Given functions are:

$u(x)=-x+3x^{2} -8$

$v(x)=2x^{2} +8x^3+9x$

$y(x)=x^{2} +3x^5+4$

$z(x) =7x^{2} +2x^3-3$

<h3>What is a quadratic function?</h3>

A function of the form $f(x)=ax^{2} +bx+c$ with $a\neq 0$ is called a quadratic function means the highest exponent of polynomial should be 2.
