The solutions to the given system of equations are x = 4 and y = -9
<h3>Simultaneous linear equations</h3>
From the question, we are to determine the solutions to the given system of equations
The given system of equations are
-8x-4y=4 --------- (1)
-5x-y=-11 --------- (2)
Multiply equation (2) by 4
4 ×[-5x-y=-11 ]
-20x -4y = -44 -------- (3)
Now, subtract equation (3) from equation (1)
-8x -4y = 4 --------- (1)
-(-20x -4y = -44) -------- (3)
12x = 48
x = 48/12
x = 4
Substitute the value of x into equation (2)
-5x -y = -11
-5(4) -y = -11
-20 -y = -11
-y = -11 + 20
-y = 9
∴ y = -9
Hence, the solutions to the given system of equations are x = 4 and y = -9

To find the answer of this problem, we need to distibute and multiply all of the numbers with each other.
2x * x + 2x * 1 + 9 * x + 9 * 1
= 2x^2 + 2x + 9x + 9
= 2x^2 + 11x + 9
The answer would be the first option.
Hope this helps!
Answer:
The answer to your question is Area = 6 u²
Step-by-step explanation:
Process
To find the area of the picture divide the figure between a square and a right triangle, determine the area of each figure and finally add them up.
1.- Calculate the area of the square
Area = side x side
= 2 x 2
= 4 u²
2.- Calculate the area of the triangle
Area = base x height / 2
base = 2 height = 2
Area = 2 x 2 /2
Area = 2 u₂
3.- Total area
Area = 4 + 2
= 6 u²
Answer:
1,000,000
Step-by-step explanation:
10 to the power of 3 is 1,000.
1,000 x 1,000 = 1,000,000
