Answer:
x = 4
y = -7
Step-by-step explanation:
y = -2x + 1
4x + y = 9
4x + y = 9
4x + (-2x + 1) = 9
4x - 2x + 1 = 9
2x + 1 = 9
2x = 9 - 1
2x = 8
x = 8/2
<u>x = 4</u>
4x + y = 9
4(4) + y = 9
16 + y = 9
y = 9 - 16
<u>y = -7</u>
Correct option would be B.
Explanation: A rational number is any integer, fraction, terminating decimal, or repeating decimal. Option B is a repeating decimal hence the .... at the end of the number.

The length and width of the rectangle is 2√5m and √5m respectively
<h3>Volume of a rectangle</h3>
The formula for calculating the volume of a rectangle is expressed as:
V = lw
where
l is the length
w is the width
h is the height
If base is twice its width, then l = 2w
Substitute
10 = w(2w)
10 = 2w²
5 = w²
w = √5 m
Since l = 2w
l = 2√5m
Hence the length and width of the rectangle is 2√5m and √5m respectively
