Answer:
The solution of the system of equation in coordinate form is (2, 0)
Step-by-step explanation:
The given equation are;
2·x - y = 4....................(1)
5·x + 2·y = 10..............(2)
Multiplying equation (1) by 2 and subtract it from equation (2) gives;
5·x + 2·y - 2 × (2·x - y) = 10 - 2×4
5·x - 4·x + 2·y - 2·y = 2
x = 2
From equation (1), we have 2·x - y = 4, when x = 2, we get;
2×2 - y = 4
y = 2×2 -4 = 0
y = 0
Therefore;
The solution of the system of equation in coordinate form is (2, 0).
B. No, the rectangle cannot have x = 20 and y = 11 because x + y ≠ 32
Perimeter = 2(l + w)
Perimeter = 64
Assuming: P = 64; w = 11 ; l = ?
64 = 2(l + 11)
64/2 = l + 11
32 - 11 = l
length = 21.

Plot the graph of the function on the coordinate plane (see attached diagram). This graph has three points of intersection with x-axis. This means that the equation has three real solutions.
The given equation is the equation of 5th power, therefore, it has 5 roots. If it has three real roots, then the remaining two roots are complex.
Answer: 2 complex roots.
Answer:
2070 people.
Step-by-step explanation:
We can set up the following proportion:
Then, cross multiply, and you'll get your answer: 2070 people.
