Answer:
Option A) 1
Step-by-step explanation:
we know that
The solution of the nonlinear system of equations is the intersection point both graphs
In this problem the intersection point is (-2,-1)
therefore
The system of equations has only one solution
Use Desmos helps with graphing Hope that helps.
Y=250+2x is the amount she spends
y=12x is the amount she makes
If the amount she spent = the amount she makes then she break even
250+2x=12x
250=12x-2x
250=10x
So x = 250/10=25 necklaces she needs to sell to break even
Answer is 25 necklaces
The simplest way to do this is to use multiplication. There is 3 bread * 4 meat= 12 sandwich combinations.
