Answer:
The equations 3·x - 6·y = 9 and x - 2·y = 3 are the same
The possible solution are the points (infinite) on the line of the graph representing the equation 3·x - 6·y = 9 or x - 2·y = 3 which is the same line
Step-by-step explanation:
The given linear equations are;
3·x - 6·y = 9...(1)
x - 2·y = 3...(2)
The solution of a system of two linear equations with two unknowns can be found graphically by plotting the two equations and finding the coordinates of the point of intersection of the line graphs
Making 'y' the subject of both equations gives;
For equation (1);
3·x - 6·y = 9
3·x - 9 = 6·y
y = x/2 - 3/2
For equation (2);
x - 2·y = 3
x - 3 = 2·y
y = x/2 - 3/2
We observe that the two equations are the same and will have an infinite number of solutions
Answer:
$18.72
Step-by-step explanation:
15% of $49.50 is $7.42
$49.50 - $7.42 = $39.08
$39.08 + $37.60 = $76.68
6% of $76.68 is $4.60
$76.68 + $4.60 = $81.28
$100 - $81.28 = $18.72
Answer:
24
Step-by-step explanation:
If you use 2^5 = 32 and 2^3 = 8.
32 + 8 = 40
32 - 8 = 24 <--- Your difference
You need to use the distance formula to find the length and width of the rectangle.
length = sqrt ((-5-7)^2 + (2 - -4)^2) = sqrt 180
width = sqrt (-5--7)^2 + (2--2)^2 = sqrt 20
Area = sqrt180 * sqrt 20 = sqrt 3600 = 60 Answer
Answer:
√65 or 8.06225
Step-by-step explanation:
√(5 – 1)^2 + (5 – –2)^2
√(4)^2 + (7)^2
√16 + 49
√65
Cannot simplify √65
