Answer:
"line of reflection."
Step-by-step explanation:
It appears as though the figure on the left is a reflection of the figure on the right across the line. Hence line P is the <em>line of reflection</em>.
Standard form (which I assume is what they want you to turn these into) is y=mx+b.
12x-5y=20 is y=2.4x-4.
Subtract 12x from both sides, -5y=-12x+20.
Multiply both sides by -1, 5y=12x-20.
Divide both sides by 5, y=2.4x-4.
y=x+4 is already in standard form- I'm not quite sure what to do.
3x+y=3 is y=-3x+3.
Subtract 3x from both sides, y=-3x+3.
x=-y+3 is y=-x+3
Ad y to both sides, y+x=3.
Subtract x from both sides, y=-x+3.
Answer:
EASY. x=-3
Step-by-step explanation:
You need to divide 21 by -7. You'll get the same answer as me
Hope this helped!!
