Answer:
Part 1) 
Part 2) 
Part 3) 
Step-by-step explanation:
we have
The parent function is 
This is a vertical parabola open upward with vertex at origin (0,0)
Part 1) Reflection over the x-axis
The rule of the reflection across the x=axis is equal to
(x,y) ------> (x,-y)
so
f(x) -----> g(x)
The function g(x) will be

Part 2) Horizontal shift left 3 units
The rule of the translation is
(x,y) ------> (x-3,-y)
so
f(x) -----> g(x)
The function g(x) will be

Part 3) Vertical shift up 7 units
The rule of the translation is
(x,y) ------> (x,y+7)
so
f(x) -----> g(x)
The function g(x) will be

Answer:
A. 3(y+2)
Step-by-step explanation:
B wouldn't work because it would be safe to assume that it represents the quintuple of the sum. C also wouldn't work because although the y is tripled, the 2 isn't. And D wouldn't work because it is only tripling 2.
A should be your answer since you are distributing the number 3 which is the same thing as a triple to get the sum of the answer which is 3y + 6.
Answer:
You would expect to get 50 heads
Step-by-step explanation:
Each time you flip a coin you will either get heads or tails. This means that you have a 1/2 probability of getting heads. If you use this then you need to multiply 1/2 and 100 to get the expected amount of heads. Multiplying by a half is just dividing by 2. Therefore, the answer is 100/2 = 50. The answer is 50 heads
