Points R(2,-1) and S(-5,3) are in the standard (x,y) coordinate plane. What is the length of RS in coordinate units?
Lelechka [254]

\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ R(\stackrel{x_1}{2}~,~\stackrel{y_1}{-1})\qquad S(\stackrel{x_2}{-5}~,~\stackrel{y_2}{3})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ RS=\sqrt{[-5-2]^2+[3-(-1)]^2}\implies RS=\sqrt{(-5-2)^2+(3+1)^2} \\\\\\ RS=\sqrt{49+16}\implies RS=\sqrt{65}

One root of a third degree polynomial function f(x) is –5 + 2i. Which statement describes the number and nature of all roots for
zheka24 [161]
Given the root of -5+2i, we are asked to describe the best statement that describes the polynomial. The root  -5+2i cannot exist without its conjugate root, -5-2i. Complex roots are always accompanied by at least 1 real root. Since there are only 3 roots, there should be one root only, hence the answer is B.<span>

What is the answer for 1/4 ( 12x + 24 ) -9x
Gekata [30.6K]

The final expression is -6x+6

Step-by-step explanation:

The expression that we have is

\frac{1}{4}(12x+24)-9x

In order to solve the expression, we start by applying the  distributive property to the bracket. We get:

\frac{1}{4}\cdot 12x + \frac{1}{4}24 -9x

Simplifying,

3x+6-9x

Now we add the two terms in x, and we find:

(3x-9x)+6=\\-6x+6

Which is the final expression.
