I just did one of these. I guessed that normal form is

Here' that's


Choice b
<u>Answer</u>
y = -x
y = (3/2)x - 5
<u>Explanation.</u>
the sum of 2 numbers is 0
That will be,
x + y = 0
Adding x both sides we get,
y = -x
The other statements is,
3x - 2y = 10
Adding 2y on both sides we get,
3x = 10 + 2y
Subtracting 10 both sides we get,
2y = 3x - 10
Dividing both sides by 2 we get,
y = (3/2)x -5
Answer:
<h2>x = 10√3 and y = 10</h2>
Step-by-step explanation:
We have the triangle 30° - 60° - 90°. The sides are in ratio 1 : √3 : 2.
<em>(look at the picture)</em>.
We have 2a = 20. Therefore a = y = 20 : 2 = 10 and a√3 = x = 10√3
