A breathalyzer test is used by police in an area to determine whether a driver's blood alcohol content (BAC) is above the legal limit. The device is not totally reliable: 5.8% of drivers who have not consumed too much alcohol give a BAC reading from the breathalyzer as being above the legal limit, while 10.7% of drivers who have consumed too much alcohol will give a BAC reading below that level. Suppose that in fact, 6.9% of drivers are above the legal alcohol limit, and the police stop a driver at random.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

x=5

step-by-step explanation:

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

your answer is -9
