Answer:
C
Step-by-step explanation:
The rule tells you that (x,y) -> (x + 1, y - 3), so you take each vertice and add one to the x-values, and subract 3 from the y-values.
(-6, 4) -> (-6 + 1, 4 - 3) which simplifies to (-5, 1)
(-3, -2) -> (-3 + 1, -2 - 3) which simplifies to (-2, -5)
(2, 1) -> (2 + 1, 1 - 3) which simplifies to (3, -2)
Answer:
Step-by-step explanation:
<u>Given inequality:</u>
<u>Solve it:</u>
The graph includes the number line to the right of 5 and the 5 is included, so this point is represented by a full dot.
Correct choice is A
Let Sydney's age be x
Christine's age is 2x
Sum of their age is 54
x + 2x = 54
3x = 54
x = 18
Sydney is 18 years old.
