Answer:
(2,-2)
Step-by-step explanation:
The first step is to substitute y in the first equation with the right side of the second equation because they both equal to y.
-3x+4 = 4x-10
-3x-4x+4-4 = 4x-4x-10-4
-7x = -14
-7x/-7 = -14/-7
x = 2
Plugin 2 for x for either equation to solve for y, I'll be using the second equation, but either one is fine.
y = 4(2)-10
y = 8-10
y = -2
Plugin x = 2 and y = -2 into (x,y), and you get (2,-2)

Answer:
33.3%
Step-by-step explanation:
Step one:
given data
Initial population (1980)= 12000
Final population(1990)= 16000
change in population= 16000-12000= 4000
Step two:
% increase= change in population/initail population *100
%increase= 4000/12000*100
%increase= 0.333*100
% increase= 33.3%
First find the LCD. That is 8.
1/2 = 4/8
7/8 + 4/8 = 11/8 or 1 3/8
7.0 thats your answer if its wrong pls dont hate me
