Find parametric equations and symmetric equations for the line of intersection of the given planes. x + y + z = 5, x + z = 0
oee [108]

The next set is the parametric equations of the same line .

x = t, y = 5 and z = -t .

What is the meaning of parametric and non parametric?

  • The assumptions behind parametric statistics relate to the population's distribution from which the sample was drawn.
  • Since no presumptions are made while using nonparametric statistics, data can be gathered from samples that do not fit any particular distribution.

x + y + z = 5, x + z = 0

the line satisfies

x + z = 0 , y = 5

thus

x = t, y = 5 and z = -t .

the first one is technically already the symmetric equations of the line.

thus:

x = -z ; y = 5

the next set is the parametric equations of the same line .

x = t, y = 5 and z = -t .

Write a rule describing the results when one multiplies three positive and negative decimals and changes the order of multiplica
anygoal [31]

Answer:

2 positive * 1 negative = negative

2 negative * 1 positive = positive

Step-by-step explanation:


one positive and 2 negative

(+ * -) * - =

positive times negative = negative * negative = positive

(+ * -) * -  = +

now if we change the order by putting parenthesis

+ *( - * -)

negative time negative = positive

+ * (+) = positive

the result is positive


The result does not change because of where we put the parentheses.


- * + * + =

negative  times positive = negative

negative * positive= negative

- * + * + =  negative

The order does not matter

What is the equation, in slope-intercept form, of the line
Roman55 [17]
Y= 1/8 x + 10

You do 8-11/-16-8= -3/-24= 1/8 that’s your slope

Then to get y intercept you plug in ur slope and coordinates of (8,11) into point slope form. And you get that the y intercept is 10.
