Divide -3
-3/-3a = 15/-3
a = -5
Circumference of a circle = 2pir
2pi(5) = 10pi
I am pretty sure the value of ‘n’ is 2.5!
Answer: 1.3 is her interest rate hopefully I'm correct on this
y = −2x + 1
4x + 2y = −1
Replace Y in the second equation with the value of Y in the first one.
4x + 2(-2x +1) = -1
Distributive Property:
4x + -4x + 2 = -1
Combine like terms:
2 = -1 which is not true, so there are no solutions.
