This is just simple. For example you have a plane of the form x=a, then you just substitute x with a, and you'll get an equation with y and z only, hence you have a 2-d trace of the intersection. It is just similar for y=b and z=c.

(1) At z=1.5, 2x^2 + 5y^2 + 1.5^2 = 4 
    2x^2 + 5y^2 = 1.75
    Now you have an ellipse in the z=1.5 plane as your trace.

(2) At x=1, 2(1)^2 + 5y^2 + z^2 = 4
    5y^2 + z^2 = 2
    Now you have an ellipse in the x=1 plane as your trace.


(3) At z=0, 2x^2 + 5y^2 + (0)^2 = 4
    2x^2 + 5y^2 = 4
    Now you have an ellipse in the z=0 plane as your trace.

(4) At y=0, 2x^2 + 5(0)^2 + z^2 = 4
    2x^2 + z^2 = 4
    Now you have an ellipse in the y=0 plane as your trace.

If y= x+3/6-x, what is the value of y when x =7i?
djverab [1.8K]

Answer:

Option (2)

Step-by-step explanation:

Given :  y = \frac{x+3}{6-x}

If x = 7i

y = \frac{7i+3}{6-7i}

By simplifying denominator of the given rational expression,

y = \frac{7i+3}{6-7i}\times \frac{6+7i}{6+7i}

y = \frac{(7i+3)(6+7i)}{6^2-(7i)^2}

y = \frac{7i(6+7i)+3(6+7i)}{36-49i^2}

y = \frac{42i+49i^2+18+21i}{36+49} [Since, i² = (-1)]

y = \frac{63i-49+18}{85}

y = \frac{63i-31}{85}

y = -\frac{31}{85}+\frac{63}{85}i

Therefore, Option (2) is the correct option.

Let the equation of a line be described by Equation A:
umka2103 [35]
10y - 5x = 40   Add 5x to both sides
       10y = 5x + 40   Divide both sides by 10
          y = \frac{1}{2}x + 4

The y-intercept is 4 and the slope of the line is \frac{1}{2}.

You can find these by comparing your equation to the equation y = mx + b, where m is the slope of the line and b is the y-intercept.

BrainiestI WILL GIVE BRAINLIEST look at the right angled triangle abc
marissa [1.9K]

Answer:

x = 90°

y = 40°

z = 40°

Explanation (Concepts) :

A straight line has total 180° angle. A square has 4 sides of each 90° angle. A triangle is build up of 180° interior angle.

Workouts:

z + 90° + 50° = 180°

z = 180° - 90° - 50°

z = 40°

=================

x + 90° = 180°

x = 180° - 90°

x = 90°

==================

50° + 90° + y = 180°

y = 180° - 90° - 50°

y = 40°
