Step-by-step explanation:
Janelle expanded the expression as shown below. -4(-3x + 2/7) = -12x - 3 5/7 What errors did she make?
We are given the expression:
-4(-3x + 2/7)
Solving this expression:
Expanding the brackets
-4 × -3x + -4 × 2/7
12x - 8/7
12x - 1 1/7
Double angle (or half angle, depending how you look at it) identities:
So we have
Note that when taking the square root, we should take into account that that could yield two possible solutions, but we know 
and 
, so it's also the case that 
.
Also, the reason we have equality in the last step can be explained like so:
(not unlike the process used to complete the square)

Answer:
y=-1x-6
Step-by-step explanation:
y-y1=m(x-x1)
y-(-5)=-1(x-(-1)
y+5=-1(x+1)
y+5=-1x-1
y=-1x-5-1
y=-1x-6
