to vertically shrink a function by a factor of c, multiply the whole function by c
f(x) vertically shrunk by a factor of c would be cf(x)
so f(x)=-3|x-4| vertically shrunk by a factor of 1/2 would be
Answer:
See explanation below.
Step-by-step explanation:
Let's say,
x = number of tokens required to play one game of ping pong
y = number of token required play one game of pinball
Using the data given, the system of equations are:

Solving the system of equations using substitution method will give us:

So, one game of ping pong required 1 token, whereas one game of pinball required 4 tokens.
12 ÷ 75 = 0.16.
So she runs 0.16 miles per minute.
Hope it helps!
Answer: Probably A
Step-by-step explanation: You need to use a ruler for this, because without one its impossible to get it exact
Using the ruler though, you'd measure each side of the wall and either use a ratio of 0.5in:4ft or multiply every 0.5in by 4ft.
