Answer:
7÷(x+1)
Step-by-step explanation:
7÷(x+1)
First you need the equation y=mx+b
you plug in x and y do find b the y intercept
-5 = -1/2*4 +b
-5 = -2 + b
b = -3
y = -1/2x-3
the answer is true. if you have square with 4 cm on all sides and double it, it will become 8 cm on all sides. the first square has a perimeter of 16 and the second square has a perimeter of 32. therefore the perimeter doubles.
