Area of square/rectangle = length times width
<span>A) 2x - 7y = 13
B) 3x + y = 8
Multiplying equation B by 7
B) 21x + 7y = 56 then adding it to A
</span><span>A) 2x - 7y = 13
23x = 69
x = 3
y = -1
</span>
Only the first one works
y = 3(-1)-2 = -5
y = -(0) -6 = -6 not -2
This is a substitution problem...
Answer:
B. (2, -1)
Step-by-step explanation:
Take tracing paper and mark the origin and point m. Rotate 90 degrees clockwise around the origin. Point m will be at (2, -1).
