8 0
1. Use Difference of squares: a^2-b^2=(a+b)(a-b)
(x+k)(x-k)=0

2. Solve for x and k
x=+-k
k=+-x

strojnjashka [21]

Answer:

Rectilíneo generalmente indica una figura representativa de hacer una línea recta oa lo largo de una línea recta o en una línea recta. En términos matemáticos, es una figura plana delimitada por segmentos de línea. En otras palabras, una figura plana totalmente compuesta de segmentos de línea se conoce como figura rectilínea. Ahora bien, si te preguntas ¿qué es una figura plana? Entonces, sepa que cuando ponemos la punta de un lápiz en una hoja de papel y nos movemos de un punto a otro, sin levantar el lápiz, entonces las formas que se forman son lo que llamamos curvas planas.

Which equation best represents the relationship between x and y in the graph
iogann1982 [59]

The equation of the line is  y= 3 - 2x.

<h3>What is equation?</h3>

An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.

Given:

Coordinates (0, 3) and (2, -1)

So,

slope = -4/2=-2

and equation of line is

(y- y1) = m (x- x1)

y-3 = (-2)(x-0)

y-3 = -2x

y= 3 - 2x

Hence, the equation of line is y= 3 - 2x.

What is the equation of a line that contains point (4, –3) and is PARALLEL to –4x + y = 7?
Debora [2.8K]

Answer:

Step-by-step explanation:

First, put -4x+y=7 into y=mx+b format

move -4x to the other side (or add 4x on both sides)

y=4x+7

now, parallel lines have the same slopes, but not the same y intercepts.

So, you already know the slope of your new line

y=4x+b

now we need to find b (y intercept)

take the point (4,-3) and put it into the equation above

-3=4(4)+b

-3=16+b

move 16 to the other side (or subtract 16)

-19=b

therefore the new line will be y=4x-19

Hope this helps!

I need help pls!! 20 points I need it!!
dolphi86 [110]

Answer: About 6.71 units

Step-by-step explanation:

You use the distance formula: \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}  }.

Assign the the two points to the variables:

(x_{1}, y_{1}) =  (1, 3)\\(x_{2}, y_{2}) = (4, -3)

Substitute them in the formula:

\sqrt{(4-1)^{2}+(-3-3)^{2}}

And solve it:

\sqrt{(4-1)^{2}+(-3-3)^{2}}\\=\sqrt{(3)^{2}+(-6)^{2}}\\=\sqrt{9+36}\\=\sqrt{45}\\=6.71
