Answer:71
Step-by-step explanation:
range is the difference between the highest number and the smallest number in a group of data
Highest number=85
Smallest number=14
Range=highest number-smallest number
Range=85-14
Range=71
Answer:
y= -3x-40
Step-by-step explanation:
first distribute
y+10= -3x-30
than subtract 10
y= -3x-40
The anwser is one and two tenths
Fun fact
if f(a)=b then f⁻¹(b)=a
so
if f⁻¹(b)=a then f(a)=b
so we find f(x)=27 and the solve for x
f(x)=3x=27
3x=27
divide both sides by 3
x=9
so if f(9)=27 then f⁻¹(27)=9
problem solved
answer is 9
Answer:
a = 9
Step-by-step explanation:
you can simplify the proportion to:
use cross- multiplication
8a = 72
a = 9
