All of these answers are wrong? The sum of 8 and twice a number would be 8 + 2n. If it was twice the sum of 8 and a number it would be D. None of them are correct but D is technicllay the closest?
Answer:
4 units.
Step-by-step explanation:
As its a tangent to the y axis the radius is 0 - (-4) = 4 units.
Answer:
(7,0)
Step-by-step explanation:
Find the slope first: 4=x 2=y 1=x2 -7=y2
-7-2/1-4=-9/-3
So the slope is -9/-3
so far we have y=-9/-3x-b
then we replace
2=-9/-3(4)-b
2=-9/-3*4-b
2=12-b
12-2=10
10=b
So y=3x-10
