Answer:
Y=-3x+5
Step-by-step explanation:
The first one i dont know srry
C 3 1/2
The lines in between the number means absolute value. This means that’s when the number is simplified it would become positive. Since 3 1/2 isn’t negative it would just stay the same
Given,
The population of the county in 2000 is 844.
The population of the county in 2009 is 856.
The population of the county in 2015 is 810.
Here, the population of 2000 and 2009 is given.
As known, the value changes linearly between two points.
When the value changes linearly between two points, then value of point between given points can be obtained by interpolation.
Hence, to predict the population of county interpolation is used.
Answer:
6.18
Step-by-step explanation:
4 cups ............... 24.72
1 cup ......................... x
x = 1×24.72/4 = 6.18
Answer:
-30%
Step-by-step explanation:
currently, the perimeter is: 4 + 6 + 4 + 6 = 20 in.
when the width of 4 in is decreased by 3 in, the new width become (4-3) in = 1 in
therefore, the new perimeter is: 1 + 6 + 1 + 6 = 14 in
the change in perimeter is: 20 in - 14 in = 6 in
now, the percent of change in perimeter will be:
%
BUT because this change is a DECREASE, you have to put a NEGATIVE sign before the value to inducate that it's a decrease, so
change in perimeter = -30%
