Answer:
D
Step-by-step explanation:
Because its shifted right 3
because when its inside the sign changes. like if its +4 its going left/-4 going right if its inside only
Given :
Two equations :
-8x + 3y = -17 ....1)
3x - y = 7 ....2)
To Find :
The solution of the system.
Solution :
Multiplying equation 2) by 3 and adding with equation 1), we get :
(-8x + 3y) + 3(3x - y) = -17 + 21
x = 4
Putting above value of x equation 2) we get :
12 - y = 7
y = 5
Therefore, solution of system is ( 4,5 ).

Look at the picture.
We have three rectangles. The formula of an area of a rectangle:
l - length
w - width
Rectangle I:
Rectangle II:
Rectangle III:
The area of number 4:
Substitute:
Yards of the border is 22 yards.
Step-by-step explanation:
- Step 1: Find the perimeter of the room to find the yards of border to be used.
⇒ Perimeter = 2(length + breadth) = 2(6 + 5) = 22 yd
Answer:
(x + 5)² + (y - 4)² = 36
Step-by-step explanation:
The equation of a circle in standard form id
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (- 5, 4) and r = 12 ÷ 2 = 6 , thus
(x - (- 5))² + (y - 4)² = 6², that is
(x + 5)² + (y - 4)² = 36
