Answer:
Austin is correct.
Step-by-step explanation:
19.5 has a tens, ones, and tenths place. 8.21 has a ones, tenths, and hundredths place.
To be a function, for any X value( input) you can only have one Y(output value).
In A) there are two x values of 2, but each one has a different Y value, so this cannot be a function.
In C, there are two x values of 1, each with a different Y value, so also cannot be a function.
D) has two X values of 0, and each has a different Y value so cannot be a function.
The correct answer would be B.
Answer:
D
Step-by-step explanation:
y=2x²+2x+1.... i
y=2x+3......... ii
Equating i and ii,
2x²+2x+1=2x+3
2x²+1-3=0
2x²-2=0
x²-1=0
x=1 or -1.
From ii, if x=1,y=5
If x=-1, y=1.
The points are (-1,1) and (1,5)
I would say d, the circumcenter. Because you're, of course, working with a triangular area, but also, the flower bed is to be circular. And the only way to fit it in the triangle only makes sense to choose d.
