Two lines are parallel if they intersect.

Andreyy892 years ago

Answer:

Step-by-step explanation:

Put what you are given in the form of

y = mx + b

If both equations have the same m, the lines are parallel. For example

y = 4x + 10

y = 4x + 20

These two lines are parallel.

However

y = 8x + 40

y = 4x + 10 are not parallel even though it looks like m could be made the same by taking out 4 in each. Check them out on the graph below.

Naty bought a dress for $24.95 and a skirt for $14.95.

FrozenT [24]

Answer:

Total items = $39.90

Sales tax amount = $3.7905

Total cost = $43.691

The clerk's error is using 9.5 as sales tax amount instead of finding 9.5% of the total items

Step-by-step explanation:

Dress = $24.95

Skirt = $14.95

steps the clerk completed.

Step 1: 24.95 + 14.95 = 39.90

Step 2: 39.90 +9.5 = 49.40

Correct steps:

Total items = dress + skirt

= $24.95 + $14.95

= $39.90

Sales tax = 9.5%

Sales tax amount = 9.5% of total

= 9.5/100 × $39.90

= 0.095 × 39.90

= $3.7905

Total cost = Total + sales tax amount

= $39.90 + $3.7905

= $43.6905

To the nearest hundredth

= $43.691

Sales tax is the amount of money imposed by government on the sales of some items

Total cost is the cost of all items including sales tax

A milloniare estimates her wealth to be $2.2×10 to the nearst million dollars.what are the lower and upper bounds for the millio

Ostrovityanka [42]

Answer:

Lower bound=$2.15×10

Upper bound=$2.25×10

Step-by-step explanation:

A milloniare estimates her wealth to be $2.2×10 to the nearst million dollars.

In other words, his worth is $22 to the nearst million dollars.

To find the lower bound of the millionaire's wealth, we divide the level of precision by 2 and subtract from the millionaire's wealth.

Lower bound= 22-0.5=21.5 million dollars.

To find the upper upper bound, we add half of the level of precision to her estimate.

Upper bound =22+0.5=22.5 million dollars
