Given the following system of equations, identify the type of system. y = -x + 4

2x + 2y = 8

equivalent
inconsistent
independent

sorry, the system is indeed dependant

when the two equations are equivalent, meaning representing the same line as this is the case.

Step-by-step explanation:

y = -x + 4

<=>

y + x = 4

<=>

2x + 2y = 2*4 = 8

so the two equations are equivalent

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.

step-by-step explanation:

copy and paste, put it in google

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
