Y = x + 5
y = -5x -1
so than you make y = y so x + 5 = -5x -1 result 6x = -6 so x = -6/6 so x = -1
and than you check it
y = - 1 +5 = 4
and
y = - 5 *(-1) -1 = 5 -1 = 4
so this mean that - 1 is the solution of the system sure
Answer:
C = 6.28
A = 3.14
Step-by-step explanation:
use the equations for area and circumference to solve
C = pi d
A = pi r^2
I like to remember these using the saying Cherry pie's delicious, Apple pie's are too so Cherry = pi's delicious, Apple = pi's r 2
so with the diameter of 2 plug in to get circumference
C = 3.14 (2)
C = 6.28
and the equation for area uses radius not diameter but we know that d/2=r so radius is 1, plug in to solve
A = 3.14 (1)^2
A = 3.14 (1)
A = 3.14
