Answer:
D, or the last option.
Step-by-step explanation:
See how the rotation does not say whether it is Clockwise or Counterclockwise?
Now, what that means, is that it will, default, be CCW. I don't know why, but math teachers are like that.
Now, 80* and 10* add up to 90* (because they are both unmarked and going to the same direction).
So, 90* rotation CCW. Simple! Thus, the last option should be correct.
Hope this helps!
P.S. Stay Safe!
Answer:
60 minutes or 1 hour
Step-by-step explanation:
Set x as the amount of time she spends riding the bus
75 = time on bus + time on train
She spends 4 times as long on the train as on the bus so the time she spends on the train is 4x
75 = x + 4x
75 = 5x
x = 15 minutes on the bus
Since she spends 4 times as long on the train, we do 4 x 15 and we get 60 minutes which is 1 hour
Answer:
No solution
Explanation:
When simplified, the statement 7=17 is formed. That statement is false, so there is no solution to this equation.
Hello!
Since this is a reflection, then the new figure has to be congruent since we're not changing the size or the shape.
Now, (x, y) is located in the First Quadrant, whereas (x, -y) is located in the Fourth Quadrant. If we're going from the First Quadrant to the Fourth Quadrant, then this has to be a reflection across the x-axis.
The correct answer is "Yes, ΔP'Q'R is a reflection of ΔPQR over the x-axis." :)
Answer:
A). X = -3
Step-by-step explanation:
Step 1: Add 20 to both sides.
Step 2: Divide both sides by 7.
Step 3: Check if solution is correct.
