the ratio of 8 books to 20 books is:
now we can divide by the same number so:
SO is option A)
Answer: a) reflected over x-axis and reflected over y-axis
<u>Step-by-step explanation:</u>
Reflection over the x-axis changes the sign of the y-coordinate
Z = (x, y) → Z'(x, -y)
Reflection over the y-axis changes the sign of the x-coordinate
Z' = (x, -y) → Z''(-x, -y)
A = (-4, 1) → A'' = (4, -1)
B = (-3, 2) → A'' = (3, -2)
C = (-1, 2) → A'' = (1, -2)
D = (-2, 1) → A'' = (2, -1)
Answer:
No solution
Infinitely many solutions
One solution
Step-by-step explanation:
The first expression:
-2(3x - 1) = -6x -1
Expand the parentheses;
-6x + 2 = -6x -1
-6x + (-6x) = -1 -2
0 = -3
This problem has no solutions
Second expression:
2(3x-1) = 6x -2
Expand the parentheses;
6x - 2 = 6x -2
6x -6x = -2 + 2
0 = 0
This problem has infinitely many solutions
Third expression:
2(3x - 1) = -6x -2
Expand the parentheses;
6x -2 = -6x - 2
6x + 6x = -2 + 2
12x = 0
x = 0
This equation has only one solution
