Answer:
The first blank is 81
+9=x-1
The second blank is 9x+3=x^2-1
Step-by-step explanation:
For the first part, you must set up the equation (9x+3)^2 then you must multiply the exponent to the inside exponents 
+
next, simplify.
81+9=x-1
For part two, set up equation. 
Then simplify 9x+3= 
Absolute value of x minus 6 is less than y
one way is to jsut make all the x's positive, then subtract them from 6 and see if they are less
sorry for confusing, just read below

answer is (-5,1)
Answer:
Food web
Step-by-step explanation:
Food chain describes how each living organism feed.
Plants are producers because the use photosynthesis to grow and provide nutrients which animals later come to consume, because animals devour plants or animals because they cannot produce their own food like plants. The animals are known as consumers.
Fungi is also a consumer because it absorbs the nutrients available from other living organisms.
Consumers are classified into three types:
1. Carnivores are organisms that feed mainly on animals
2. Herbivores who feed on plants
3. Omnivores who feed on both plants and animals.
A food web describes the relationship between various food chains and how they interact with each other in the eco system.
Answer:
1) x≥6
--------------------------------------
--------------------------------------
2) h > 20
Mark worked more than 20 hours.
Step-by-step explanation:
1) -20x+18≥-102
-20x≥-102-18
-20x≥-120
Dividing -20 both side
≥
x≥6
--------------------------------------
--------------------------------------
2) 14h + 25 > 305
14h > 305-25
14h > 280
Dividing 14 both side
h > 20
Mark worked more than 20 hours.
