Answer:
x = -1 and y = -1.
Step-by-step explanation:
The given system of equations are :
y = 4x + 3 ....(1)
y = -x - 2 ....(2)
From equation (1) and (2) :
4x + 3 = -x - 2
Taking like terms together,
4x + x = -3 -2
5x = -5
x = -1
Put the value of x in equation (1)
y = 4(-1) + 3
= -1
The solution is also shown in the attached figure. Hence, the solution is x = -1 and y = -1.
Answer:
326
Step-by-step explanation:
First you find the area of the triangles. Since squares have equal sides we know that the triangle has a side of 20 and 12. We plug this information into the formula A=20x12/2 which equal 120 but since we have 2 triangles we multiply by 2 and get 240. Then we find the area of the square which is 400 when you multiply 20x20. Then you find the area of the circle which is 3.14x10^2 which equals 314. You add 240 and 400 to get 640. You subtract 460 from 314 and get 326.
