4 units, because a translation is a rigid motion, meaning it preserves segment length.
Answer: (x, y) —> (-x, y)
Step-by-step explanation:
This is because the translation rule for reflection across the y-axis is (x, y) —> (-x, y)
Answer:
(x + 1)² + (y - 3)² = 8
Step-by-step explanation:
radius (r): √(1 - (-1))² + (1 - 3)² = √8 = 2√2
Formula for circle with center (h,k): (x – h)² + (y – k)² = r²
(x + 1)² + (y - 3)² = 8
I'm pretty sure you just add all the numbers up so it would be 569.9 ft
Answer:
Plan A last 0.75 hours or 45 minutes.
Plan B last 1.5 hours or 90 minutes.
Step-by-step explanation:
Let
be the number of hours that the plan A last, an
the number of hours of plan B. Then for the Wednesday you have:

And for the Thursday is:

Multiply the equation of Wednesday by -3:

Using the method of addition using this last equation and the equation of Thursday

Replacing the value of
in one of the equations
