3 no. Answer is 33 in my gess
let's recall that in a Kite the diagonals meet each other at 90° angles, Check the picture below, so we're looking for the equation of a line that's perpendicular to BD and that passes through (-1 , 3).
keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of BD
so we're really looking for the equation of a line whose slope is -1/3 and passes through point A

Answer:
between 0 and 1: divide 1 by 2 = 0.5
between 1 and 1/2: divide 1/2 by 2 (0.25) and multiply that by 3 = 0.75
What you would do is combine the terms with variables, and combine the terms without.

I hope I got all of these right if not that’s embarrassing haha I did all of them in my head I’m pretty sure they’re right
I hope I helped
Answer:
x = -1, and y = -2, giving you the answer (-1, -2)
Step-by-step explanation:
In the second equation, we're told that y is equal to 2x. With that, we can replace "y" in the first one with "2x", giving us:
-4x - 2x = 6
-6x = 6
x = -1
Now that we know the value of x, we can simply plug it into the first equation to find y:
-4x - y = 6
-4(-1) - y = 6
4 - y = 6
-4 + y = -6
y = -6 + 4
y = -2
So x = -1, and y = -2
