To find the mean add up each value and divide by the number of values
Planted society- 40+20+16+20+17+12+15=140
140/7=20
Bees park- 25+12+9+15+35+20+6+30=152
152/8=19
planted society’s mean was larger
Do 4x+7=11x-9 subtract 4x to 11x so you get 7x. Now your left with 7=7x-9 then you add 9 to the 7 which is 16 and your answer is x=16/7
Answer:
Since x = -2 produces y = 4 and y = 1
