What number must be added to the expression below to complete the square? x^2+x. a.1/4 b.1/2 c.2 d.1

torisob [31]

Option a. 1/4 is the right answer

Step-by-step explanation:

Given expression is:

$x^2+x$

Here

we know that

a = x

In order to find the number which should be added

comparing with the formula

$(a+b)^2 = a^2+2ab+b^2$

$2ab = x\\2.x.b = x\\b=\frac{x}{2x}\\b = \frac{1}{2}$

So, we will add the square of 1/2 which is 1/4

Hence,

Option a. 1/4 is the right answer

Find the x- and y-intercepts of 5x - 3y = 12 .

irga5000 [103]

X = (12/5,0)
y = (0,-4)

substitute 0 in for y & solve for x , to find the y-intercept substitute 0 in for x and then solve . ( I hope that makes sense)

(-2, 11) & (5,6) What is the slope of the equation between these two points?

ololo11 [35]

Answer:

$m =\dfrac{-5}{7}$

Step-by-step explanation:

Given :-

Two points (-2,11) and (5,6) .

And we need to find out the slope of the equation between the two points. The slope of the line passing through two points , is given by ,

$\implies Slope (m) =\dfrac{ y_2-y_1}{x_2-x_1}$

Here the two points are (-2,11) and (5,6) .So put on the respective values ,

$\implies Slope (m) =\dfrac{ 11 - 6}{-2-5}\\\\\implies Slope = \dfrac{5}{-7} \\\\\implies Slope = \dfrac{-5}{7}$

Hence the slope of the line is -5/7 .
