Rotating a figure 90° counterclockwise about the origin results in an ordered pair (x, y) mapping to its image (-y, x). Thus point C, which is at (3, 5), will map to (-5, 3).
Question: -0.5, -0.67, -2/3, -13/20, -17/25
Answer: = −19
/6
Answer:
AB = 5/4 y - 1 = 5/4 (12/13) -1 = 2/13
AC= 7/3 y - 2 = 7/3 (12/13) -2 = 2/13
Step-by-step explanation:
Because it is a equilateral triangle, it means all sides have the same length.
AB = AC
5/4 y - 1 = 7/3 y - 2
5/4 y - 7/3 y = -2 +1
-13/12 y = -1
y = 12/13
input y to the equation.
AB = 5/4 y - 1 = 5/4 (12/13) -1 = 2/13
AC= 7/3 y - 2 = 7/3 (12/13) -2 = 2/13

Answer:
X = 0.87
Step-by-step explanation:
BODMAS
B - Bracket, O - Of, D - Division, M - Multiplication, A - Addition, S - Subtraction
Multiplication comes before addition and subtraction in the order, so
75X - 62 + 9 = 12
75X - 53 = 12
Add 53 to both sides
75X -53 + 53 = 12 + 53
75X = 65
Divide both sides by 75
X = 0.87
