Answer:
(-2, 6)
Step-by-step explanation:
We can simply do this by plugging in all of the coordinates. (I did this in my head quickly, so I know what it is; I'm just going to plug in the correct answer.) The correct answer is (-2, 6), so we're just going to plug them into the simplest equation, which is probably y=-3x. So...
6=-3(-2)
6=6
This answer is correct. If you're unsure about the answer, you can always check in the other equation. So...
3(-2)+2(6)=6
-6+12=6
6=6
Hope this helps and have an amazing day ^^
Answer: (x+1)^2=12(y-2)
Step-by-step explanation:
Proportions have two fractions so the answer is ratios.
Hope it helps :)
Answer:
there is 16 oz in a pound
so if you divide 4.00 by 16 you get 0.25 a oz so if we do the inverse operation
0.25 x 16= 4.00
Step-by-step explanation:
Answer:
x =3, y =3
Step-by-step explanation:
From the second equation( y= -x+6) we can get x alone.
Subtracting 6 from both sides we get, y-6 = -x
And then dividing both sides by -1, -y+6 = x
Then we can substitute this value of x into the first equation.
y = 2(-y+6) +3
Simplifying,
y = -2y + 12+ 3
3y = 15
y = 3
Substituting this back into second equation we get 3 = -x + 6
and -x = -3
Dividing both sides by -1,
we get x =3
