Answer:
Step-by-step explanation:
Given that:
The differential equation; 
The above equation can be better expressed as:

The pattern of the normalized differential equation can be represented as:
y'' + p(x)y' + q(x) y = 0
This implies that:



Also;


From p(x) and q(x); we will realize that the zeroes of (x+2)(x-2)² = ±2
When x = - 2






Hence, one (1) of them is non-analytical at x = 2.
Thus, x = 2 is an irregular singular point.
In the fist you have to know: a<span>ny angle opposite the head is equal in measurement.
so now we know o</span><span>ne angle in the triangle it is 82
</span><span>All corners of the triangle are equal 180
</span>so we have to do this 180-82=98
so we have to collection (4x+8)+(8x-6)=98
12x+2=98
12x=96
x=8
4(8)+8=40
the answer is 40

To solve an equation with a rational (fraction) coefficient you need to multiply both sides of the equation by the reciprocal (invert the fraction - flip it).

The reciprocal of 1/6 is 6/1 or 6

The product of reciprocals equals 1
1x = 24
x = 24
Answer:
Speed of the river =
km per hour
Step-by-step explanation:
Speed of the boat in still water = 4 km per hour
Let the speed of the river = v km per hour
Speed of the boat upstream = (4 - v) km per hour
Time taken to cover 6 km = 
=
hours
Speed of the boat downstream = (4 + v) km per hour
Time taken to cover 12 km =
hours
Since, time taken by the boat in both the cases is same,

6(4 + v) = 12(4 - v)
24 + 6v = 48 - 12v
12v + 6v = 48 - 24
18v = 24
v = 
v =
km per hour
Answer:
x=0
y=-21/7
Step-by-step explanation:
Let the two unknown be x and y
x+y=-7...(1)
x-y=14...(2)
From (1) make x the subject of formula
x=-7-y...(3)
Substitute (3) into (2)
-7-y-y=14
-7-2y=14
Add 7 to both sides
-2y=21
Add both sides by-2
y=-21/2
Substitute the value of y into (3)
x=-7-(-21/2)
x=-7+21/3
Lcm
x=-21+21/3
x=0/3
x=0
