Answer:
-11
Step-by-step explanation:
(a+b) +(c+d)
plug in
(-5+15)+(-9-12)
type in calculator
you will get your answer (-11)
I didn’t understand why she didn’t answer me because she was doing something like a teacher she was gonna
1.) True. Their scales are the same, they only vary in sizes.
2.) False. Similarities between circles can be proven by reflections(1), transformation(2), dilation(3), and rotations(4) when they map the figures.
3.) True. Refer to #2.
Each piece of this function is continuous on its respective domain (because all polynomials are continuous functions), meaning
• 2 - x exists for all x < -1
• x exists for all -1 ≤ x < 1
• (x - 1)² exists for all x ≥ 1
So this really just leaves the points where the pieces are split up, i.e. x = -1 and x = 1. At both of these points, the two-sided limit exists as long as the one-side limits from both sides exist and are equal to one another.
At x = -1, as I said in my comment, you have
while
But -1 ≠ 3, so the two-sided limit
does not exist. So a = -1 is one of the points you would list.
At x = 1, we have
while
and again the one-sided limits don't match, so this two-sided limit also does not exist, making a = 1 the other answer.
Answer:
Distributive and associative.
Step-by-step explanation:
The equation involves distributing, and rearranging the order, so the properties are distributive and associative.
