No solutions.
Step-by-step explanation:
No solutions because these two lines are parallel.
You can tell by the slopes. Both slopes are equal -3.
The -2 and vertically shift the lines.

Fourteen of the 100 digital video recorders (DVRs) in an inventory are known to be defective. It means that the probability that a randomly selected item is defective is: .
Answer:
The answer is B
Step-by-step explanation:
Answers talk about rate of change meaning slope.
For function 1 we choose two points, they specify [1,2].
Use the slope formula for points (1,-3) & (2,3) = 6
For function 2, the equation is shown in y-intercept, basically the slope is (1/4)^x and if you replace x with [1,2] you get really low values.
For function 3 is easy since you can count the units with rise/run giving and slope of 2 or 2/1. <em>(2 and 2/1 is the same thing)</em>

Subtract cost of stationary from total in account
98 - 10.85 = 87.15
Subtract cost of skateboard from new total
87.15 - 64 = 23.15
Set up an algebraic expression
23.15 = 1.65x
Divide each side by 1.65 to isolate x
x = 14.0303 or 14
