390, because 10% of 1300 is 130 so 130 times 3 = 390
Answer:
j = 2/19
Step-by-step explanation:
Step 1: Subtract 7 on both sides
-2/j = -19
Step 2: Multiply <em>j</em> on both sides
-2 = -19j
Step 3: Divide both sides by -19
2/19 = j
If the question is -2/(j + 7) = 12:
Step 1: Multiply both sides by j + 7
-2 = 12(j + 7)
Step 2: Distribute
-2 = 12j + 84
Step 3: Subtract 84 on both sides
-86 = 12j
Step 4: Divide 12 on both sides
j = -43/6 = -7.167
Answer:
Since there are no common prime factors,
the only common factor for 11
a^
3
b
^5 is 1

Step-by-step explanation:
The general equation of a given circle is
Given a plot of the circle in the X-Y plane, The center of circle has the coordinates ( -1, -1) and the circle is passing through (-1 ,-4) and (-1 ,-2) and (-1 ,-4) , (-1 ,-2) are coordinates of diametrically opposite ends of circle
If there are two points on a circle (x₁, y₁) and (x₂, y₂) that are at opposite ends of the same diameter, then the circle's equation can be written as
(x-x₁)(x-x₂)+(y-y₁)(y-y₂)=0
Given x₁= -1 , x₂ = -1 , y₁= -4 , y₂= -2
The circle's equation can be written as ( x+1)(x+1) + (y+4)(y+2)
⇒
⇒
Therefore, is the general equation of circle.
Hence,The general equation of a given circle is
