Perpendicular lines, slope is opposite and reciprocal
so slope of new line = - 4
passes through (-2, -6) in point-slope form
y + 6 = -4(x + 2)
Answer is C. y + 6 = -4 (x + 2)
I think the answer is 2,612.48 because if you multiply the radius, 80 by itself you get 640. Then if you multiply 640 by 3.14 and then multiply the product by 1.3 you get 2,612.48.

Answer:
$1.16 per meter
Step-by-step explanation:
You need to divide the coat by the meters.
9.28/8
= 1.16
So one meter of ribbon would cost $1.16.
Answer:
They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 3 times the second equation of System A.
Step-by-step explanation:
System A
2x + y = 5 --> (1)
−4x + 6y = −2 --> (2)
(1) + 3×(2)
-10x + 19y = -1
System B
−10x + 19y = −1 --> (1)
-4x + 6y = −2 --> (2)
