For a system of equations to have no real solution, the lines of the equations must be parallel to each other. The solution of the system of equation y = 5x + 3 and y = 4x + 6 is (3,18).
Inconsistent System
For a system of equations to have no real solution, the lines of the equations must be parallel to each other.
Consistent System
1. Dependent Consistent System
For a system of the equation to be a Dependent Consistent System, the system must have multiple solutions for which the lines of the equation must be coinciding.
2. Independent Consistent System
For a system of the equation to be an Independent Consistent System, the system must have one unique solution for which the lines of the equation must intersect at a particular.
The solution of the system of equations can be done as shown below, therefore,
Equation 1: y = 5x + 3
Equation 2: y = 4x + 6
Substitute the value of y from the first equation in the second equation, therefore,
y = 4x + 6
5x + 3 = 4x + 6
5x - 4x = 6 - 3
x = 3
Substitute the value of x in any one of the equation,
y = 5(3) + 3
y = 15 + 3
y = 18
Hence, the solution of the system of equation y = 5x + 3 and y = 4x + 6 is (3,18).

y=5x+3
y= 4x+6
Let's solve y=5x+3 for y
Substitute 5x+3 for y in y=4x+6
y=4x+6
5x+3=4x+6
Add -4x
5x+3-4x=4x+6-4x
x+3=6
Add -3
x+3-3=6-3
x=3
Now substitute 3 for x in y=5x+3
y=5x+3
y= (5)(3)+3
y= 15+3
y= 18

The solution is, 0.08 which is 0.4% of 20.
A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
here, we have,
to find the number which is 0.4% of 20.
so, we get,
let, the number be x
now, 20* 0.4% = x
or, 20/100= x/0.4
then cross multiply 20/250=x
x = 0.08
which 0.08
Hence, the answer is 0.08

Answer:
Option C. (4x² -3x + 9)
Step-by-step explanation:
Arranging a polynomial in descending order means to arrange the powers of variables of each term in the descending order.
So in the given options only Option C. is in the descending order.
4x² - 3x + 9
This polynomial has the variable x² with maximum degree of 2 at the starting.
Then second variable 3x with degree of 1 and then constant term 9.
Option C. is the correct option.
