7. Two students used point-slope form to find an equation that describes the line with a slope of -3 and goes through the point (-5, 2). Who is incorrect? Explain the error.
A
y - y = m(x - x)
y - 2 = -3(x - 5)
B. y - y = m(x-x.)
y-2--3[x -(-5)
y - 2 = -3(x+5)

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

i believe the correct answer is b.
