Step-by-step explanation:
y = x + 7
Using the substitution method,
-2x - 11 = y
-2x - 11 = (x + 7)
3x = -18
x = -6.
y = (-6) + 7 = 1.
The solution pair is (-6,1).
the answer should be 3 x 10⁵
180 degrees counterclockwise because 360 degrees is a full circle and 180 is half a circle because 6x2=12
C=2(3.14159...)R
You’re given the circumference, so all you need to do is plug that in and simplify.
36=2(3.14159...)R
36=6.28R
36/6.28=R
R is about 5.73
