Answer:
x=3 and y= -1
Step-by-step explanation:
Step 1: Solve2x+y=5 for y:
2x+y=5
2x+y+−2x=5+−2x(Add -2x to both sides)
y=−2x+5
Step 2: Substitute−2x+5foryin5x+3y=12:
5x+3y=12
5x+3(−2x+5)=12
−x+15=12(Simplify both sides of the equation)
−x+15+−15=12+−15(Add -15 to both sides)
(Divide both sides by -1)
x=3
Step 3: Substitute3forxiny=−2x+5:
y=−2x+5
y=(−2)(3)+5
y=−1(Simplify both sides of the equation)
Answer:
x=3 and y=−1

Step-by-step explanation:
Answer;
-The populations of grasshoppers, mice, and snakes would decrease.
Explanation;
-The food web or a food chain describes the series of relationships that occur between predators and prey in an ecosystem.
-Several types of life forms form the food web. Green plants that can make their own food through photosynthesis are the web's producers. They form the bottom of the chain. Animals that get food from other animals and plants are consumers. Decomposers feed off dead plants and animals because decomposers cannot make their own food.
-If producers were removed in a food chain then, all the other animals in the food web would die too, because their food supplies would have died out. The populations of the consumers would fall as the population of the producer fell.
Answer:
Step-by-step explanation:
The slope of the line would be the constant of proportionality for the line
shown. The point (35, 49) is really close the line which would make the
constant of proportionality 49/35 = 7/5. The equation of the line would be y =
7/5x. The number of loaves of bread from 85 pounds of flour would be
7/5(85) = 119 loaves.
