Answer:
7.A (5,1)
B(5,7)
8. D (0,6)
Step-by-step explanation:
7. One vertex is at (5,4)
Move 3 units either direction in x
(5-3,4) = (2,4)
(5+3,4) = (8,4)
Or move 3 units in the y direction
(5,4+3) = (5,7)
(5,4-3) = (5,1)
If x is less than 2 or greater than 8 it is too far from the one vertex we are given
If y is less than 1 or greater than 7 it is too far away from the one vertex we are given
C cannot be a vertex since y =9
D is not a vertex since the point is (2,6) and not (2,4) which we know is 3 units away
E is not a vertex since the point is (2,1) and not (2,4) which we know is 3 units away
8. The center is (0,0)
The points have to add to a radius of 6
r^2 = 36
The sum of the x^2 and y^2 = 36
3^2 +0^2 = 9
4^2 +2^2 = 16+4 = 20
5^2 +3^2 = 25+9 = 34
0^2+6^2 =36 yes for D
4^2 +4^2 =16+16 = 32
1^2+5^2 = 26
4 divide 4/9
4 times 9/4
= 9
Answer:
5
Step-by-step explanation:
Answer:
(x,y) maps to (-y,x).
Step-by-step explanation:
Use vertex I as an example.
Pre-image I is graphed at point (-3,2), while image I' is graphed at point (-2,-3) .
In order to change between these points, the x and y coordinates must be swapped, as well as multiplying the y coordinate by -1.
Answer:
x = 25
y = 6
Step-by-step explanation:
< B = < M
2x - 20 = 30
2x = 50
<u>x = 25</u>
AB = LM
7y - 8 = 2y + 22
5y = 30
<u>y = 6</u>
