Answer:

perpendicular

Step-by-step explanation:

Let's find the slope of both lines

For line 3x-6y=-1

-6y=-1-3x

y=1/6+½x

m=½

For line 18x+9y=-14

9y=-14-18x

y=-14/9-2x

m=-2

m1•m2=½×-2=-1

since m1•m2=-1 the lines are perpendicular

Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall. Sean's video game system measures 1 inch lon

Lady_Fox [76]

Answer:

Combined volume of the two game systems $=416$ cubic inches

Step-by-step explanation:

Volume of a cuboid = length × breadth × height

Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall.

So,

Volume of Soham's video game system = 8 × 6 × 2 = $96$ cubic inches

As Sean's video game system measures 1 inch longer on all sides,

the video game system measures $8+2=10$ inches long, $6+2=8$ inches wide, and $2+2=4$ inches tall.

Volume of the video game system = 10 × 8 × 4 = $320$ cubic inches.

Therefore,

Combined volume of the two game systems = $96+320=416$ cubic inches

One of four calculator batteries is bad. An experiment consists of testing each battery until the dead one is found.

denpristay [2]

Answer:

(a) 4 possible outcomes

(b) Not possible, testing stops upon finding the bad battery,

Step-by-step explanation:

Let G denote a good battery and B denote a bad battery.

Whenever a bad battery is found, the batteries stop being tested.

(a) The outcomes for this experiment are:

GGB

GGGB

There are 4 possible outcomes.

(b) The outcome GBGG is not possible since testing stops upon finding the bad battery, the outcome in this case would be GB.
