Answer:
-5x - 7y
Step-by-step explanation:
Answer:
y = -2x -2
x + 2y = 2
2x + y = -2 } x1
x + 2y = 2 } x2
2x + y = -2 } we eliminate 2x
2x + 4y = 4 } same signs subtract and different add respectively
-3y = -6
-3 -3
y = 2 (x , 2) we reserve
2x + (2) = -2 we take on the first equation and replace 2 on a coordinate for y
2x = -2 - 2
2x = -4
2 2
x = -2 (-2,2)
x y
We just have to multiply 20 by 10mm, which is 200mm. 100mm is equal to one centimeter, so the body length of the insect under the microscope is two centimeters.
