The two numbers are 12 and 16. 12 + 6 = 18. 6 doubled is 12. 12 plus 6 equals 18.
Answer:
A = (0, -8)
Step-by-step explanation:
B = (A+C)/2 . . . . the midpoint is the average of the end points
A = 2B -C = 2(-3, -5) -(-6, -2) . . . solve for A, substitute point values
A = (0, -8)
Answer:
The answer is B
Step-by-step explanation: After solving this equation using y=mx+b
I got y=-4x+7
So they give us the slope which is negative 4
so you would throw in the x coordinate with the slope and multiply to get y=-12+7
then you would use the y coordinate to substitute the Y
-5=-12+7
i add twelve on both sides and end up with the y intercept being 7]
so I add them into the equation and got y=-4x+7
