<span>f(x+5/4) means that f(x) is translated 5/4 units left.
f(x-5/4) means that f(x) is translated 5/4 units right.
f(x)-5/4 means that f(x) is translated 5/4 units down.
f(x)+5/4 means that f(x) is translated 5/4 units up.
f(x*5/4) means that f(x) is compressed by a factor of 5/4.

answer
≈ 0.31 = 31 %
set up equation
the probability of someone from the first group having brown eyes is 
the probability of someone from the second group having brown eyes is 
so the probability of both students having brown eyes is*
values
students with brown eyes in first group = 27
total students in first group = 40
students with brown eyes in second group = 23
total students in second group = 50
plug in values and solve
*
= 
= 
=
≈ 0.31
= 31 %
Answer:
750 + 750=1500
Step-by-step explanation:
Solve each
5x+7>-8
minus 7 both sides
5x>-15
divide by 5
x>-3
3x+7≤19
minus 7 both sides
3x≤12
divide by 3
x≤4
so we got
x>-3 AND x≤4
and means that the solution set must satisfy both at once
so x is bigger than -3 and less than or equal to 4
so between -3 and 4 including 4
-3<x≤4
last one
