<span>The y variable has the same coefficient so use elimination (subtract equations).

    -2x = 8 - 6y
-(-15x = 21 - 6y)
------------------------
    13x = -13 + 0

x = -1
Use this to find y in either equation. </span>
<span>-2(-1) = 8 - 6y
2 = 8 - 6y
2 - 8 = -6y
-6 = -6y
y = 1

(x,y) = (-1, 1)

An object travels along a circular path so that it completes one revolution in 8 seconds. If the linear velocity of the object i
natima [27]

Answer:

Using the concept of speed-distance-time, we find that the diameter of the circular path is 12 inches.

Step-by-step explanation:

Given that the object completes one revolution in 8 seconds. So, the circular speed of the object is 2πr/8 = πr/4 inches per seconds, where r is the radius of the circular path. The speed can be written as:

πr/4 inches per seconds = 60πr/4 inches per minute = 15πr inches per minute.

But, it is given that the circular speed of the object is 90π inches per minute. So,

90π = 15πr

r = 6 inches

Since, diameter is the double of radius, d = 2r = 12 inches.

What is the general form of the equation of a circle with its center at (-2,1) and passing though (-4,1) ?
julsineya [31]
Equation is :( x + 2 )² + ( y - 1 )² = r²( - 4 + 2 )² + ( 1 - 1 )² = r²4 = r², than we will plug in to a formula:( x + 2 )² + ( y - 1 )² = 4x² + 4 x + 4 + y² - 2 y +1 = 4x² + y² + 4 x - 2 y + 1 = 0
the answer is : <span>x2 + y2 + 4x − 2y + 1 = 0 </span>
