Without graphing, is the system independent, dependent, inconsistent? {12x=3y=12 y=-4x+5

1 answer:

7 0

Okay so you out them into the form of y=mx+b. since equation 2 is already like that you need to do it to equation 1. which is y=-4x+4. graph both equations. if it has a solution (1 point where the two lines meet) it is consistantly and independent. if they are parallel lines and the solution is 0 the system is inconsistent and the lines are dependent. if it's the same line they are consistent and dependent. the line is not the same since the y intercept is different. the slope is the same though which tells us its parallel. so the system has a solution of 0 and is inconsistent and the lines are independent.

nordsb [41]

Answer:

4.It is continuous because the number of gallons can take on any value over a range of values.

Step-by-step explanation:

Discrete variables are ones that are disconnected. This means they take only specific values, with no values inbetween.

Continuous variables are ones that can take any value in a given range.

When measuring the gallons of gas, we can have partial gallons of gas; this means the variable can take any value in a given range, so it is continuous.
