Answer:
s = 14
Step-by-step explanation:
Step 1: Combine like terms.
Step 2: Multiply both sides by 2/3.
Answer: The answer is (D) Reflection across the line y = -x.
Step-by-step explanation: In figure given in the question, we can see two triangles, ΔABC and ΔA'B'C' where the second triangle is the result of transformation from the first one.
(A) If we rotate ΔABC 180° counterclockwise about the origin, then the image will coincide with ΔA'B'C'. So, this transformation can take place here.
(B) If we reflect ΔABC across the origin, then also the image will coincide with ΔA'B'C' and so this transformation can also take place.
(C) If we rotate ΔABC through 180° clockwise about the origin, the we will see the image will be same as ΔA'B'C'. Hence, this transformation can also take place.
(D) Finally, if we reflect ΔABC across the line y = -x, the the image formed will be different from ΔA'B'C', in fact, it is ΔA'D'E', as shown in the attached figure. So, this transformation can not take place here.
Thus, the correct option is (D).
Answer:
Step-by-step explanation:
First, let's call "a number": n
Then. "eight less than a number" can be written as: n-8
This expression "is no more than 14" can be written as: n−8≤14
[13,22]
Answer:
Step-by-step explanation:
There are 2 cups in 1 pint.
Sara gets 2 * 7 = 14 cups
She pays 20 dollars.
Tatiana buys 15 1/2 cups for 20 dollars. In effect, Tatiana got 1.5 cups free, so she got the better deal.
