Answer:
- 20 and 31
Step-by-step explanation:
Solve the given equations simultaneously to find x and y
2x + y = 23 → (1)
4x - y = 19 → (2)
Adding the 2 equations term by term will eliminate y
6x + 0 = 42
6x = 42 ( divide both sides by 6 )
x = 7
Substitute x = 7 into either of the 2 equations and solve for y
Substituting into (1)
2(7) + y = 23
14 + y = 23 ( subtract 14 from both sides )
y = 9
Then
x - 3y = 7 - 3(9) = 7 - 27 = - 20
5y - 2x = 5(9) - 2(7) = 45 - 14 = 31
Answer:
18
Step-by-step explanation:
Adding 6 and 3 gives you the full length of the long side of rectangle and since 3 is the radius of the circle, the short side if the rectangle would also be equal to 3.
So, the long sides equal 9 and the short sides are 3, making the perimeter 18

Answer:
2. (1.5, 1.5)
Step-by-step explanation:
midpoint = (x1+x2)/2 , (y1+y2)/2
A = (-3,-3) and B = (6,6)
midpoint = (-3+6)/2, (-3+6)/2
= 3/2 , 3/2
