There are 220 pages in carly's novel. At 4 hours, there is 80 pages left, but monica has 120
Answer: (-2, -2)
Step-by-step explanation:
Reflection over the x-axis: (x, y) → (x, -y)
(-2, 2) → (-2, -2)
x would remain the same but the y would turn negative since we're reflecting over the x-axis. The x never changes in this situation but since we're flipping it over the x-axis, they y has to be negative.
Hope this helps!
Answer:
true
Step-by-step explanation:
1/2 (sin(x+y)+sin(x-y))
= 1/2 (sin x cos Y + cos x sin y + sin x cos y - cos x sin y)
= 1/2 * 2 sin x cos y
= sin x cos y
The expression is true.
Answer:
4 friends evenly divided up a n -slice pizza.
So, the number of slices each friend received = n/4
Now, Harrison ate 1 fewer slice than he received. As he received n/4 slices, so 1 fewer than n/4 means......
Harrison ate n/4-1 slices of pizza.
