Answer:
(1 , 3)
Step-by-step explanation:
→ Make equations equal to each other
2x + 1 = 4x - 1
→ Solve
-2x = -2
→ Divide by 2 on both sides
x = 1
→ Substitute x = 1 into the y = 2x + 1
2 × 1 + 1 = 3
Answer:
Your answer should be option 2
Step-by-step explanation:
those || lines mean parallel and the lines DE and AC are parallel.
Answer:
4(2x-y) (2x+y)
Step-by-step explanation:
The area of the picture is 2y*2y = 4y^2
The area of the picture and the frame is 4x*4x = 16x^2
The area of the frame is The area of the picture and the frame minus The area of the picture
The area of the frame = 16x^2- 4y^2
Factor out a 4
4(4x^2 -y^2)
This is the difference of squares
a^2 – b^2 = (a + b)(a – b)
a^2 = 4x^2 so a=2x
b^2 = y^2 so b=y
4(4x^2 -y^2) = 4(2x-y) (2x+y)
j+47=55
Subtract 47 from both sides.
j= 8
