Answer:
m = -6/7
b = -2
Step-by-step explanation:
m = (y2 - y1)/(x2 - x1) = (-2 - 4)/(0 - (-7)) = -6/7
y = mx + b
m = -6/7
y = -6/7 x + b
Use point (-7, 4).
4 = (-6/7)(-7) + b
4 = 6 + b
b = -2
y = -6/7 x - 2
m = -6/7
b = -2

Answer:
Step-by-step explanation:
You need to bring the -5 to the left side.
x^2-6x+5=0
Wat two numbers, when multiplied equal to +5? Also when added make the middle term or -6? -5 and -1.
(x-1)(x-5) The x^2 would factor to be x*x
So the answer is the (x-1)(x-5)
I think its (6.5+3.25)÷0.2=48.75
dont quote me on that, I tried and I'm not the best at math lol.
Answer:
139
Step-by-step explanation:
First we need to find diameter 132/3.14=42 rounded
Then we halve it to find radius 42/2=21
Formula for area is radius x radius x 3.14
21 x 21 = 441 x 3.14 = 138.74 round up is 139
