Answer:
(-1,-2)
Step-by-step explanation:
I graphed the equation on the graph below so you can see that (-1,-2) is a solution.
5(z-4)-z=4z-20
5z-20-z=4z-20
4z=4z
z=z
The answer is C
Answer:
x is infinite
Step-by-step explanation:
x is a function so
if y=f:x
therefore

(m+2)(m+3)= (m+2)(m-2)
⇒ m^2+ 3m+ 2m+ 6= m^2 -4
⇒ 5m+ 6= -4 (m^2 on both sides cancels out)
⇒ 5m= -4-6
⇒ 5m= -10
⇒ m= -10/5
⇒ m= -2
The final answer is m=-2~
Answer:
That is the system.
y = x - 4
y = 4x - 10
If you are looking for the solution then use the method of substitution or the method of elimination.
