Answer:
1. -4
2. 10
3. -19
4. 5
Step-by-step explanation:
1. 5 + -9= -4
2. -3 + 13 = 10
3. -8 + 11 = -19
4. 6 + -1 = 5
Answer:
For 6: A
For 7: B
Step-by-step explanation:
It requires graphing. For circumcenter, you draw a perpendicular line from each vertex to opposite side of that vertex and the intersection of those lines is the point of circumcenter.
Answer:2/pi
Step-by-step explanation:
First, name the points. Top Left will be A, Top Right will be B, Bottom Right will be C, and Bottom Left will be D. Now, the area of ABCD is 4. Then, we have to find the area of the circle. The center to the midpoint of AB is 1. The length of the midpoint of AB to B is 1. So, using the Pythagorean Theorem, it will be 1^2 + 1^2 = 2, then it will be sqrt2. Finding the area of the circle will be easy now that we have the radius. sqrt2*sqrt2*pi = 2pi. So, it will be 4/2pi, and simplified, it will be 2/pi.
Answer:
Neither
Step-by-step explanation:
equation 1 is a negative slope, equation 2 is a positive slope, but with a different slope.
