Answer:
Step-by-step explanation:
Dilating with a scale factor of 3 centered at the origin means we multiply all the coordinates by 3.
- (0,2) maps onto (0,6).
- (0,4) maps onto (0,12).
- (3,2) maps onto (9,6).
- (3,4) maps onto (9,12).
Therefore, the answers are the second option and the sixth option.
The formula for distance problems is: distance = rate × time or d = r × t
Things to watch out for:
Make sure that you change the units when necessary. For example, if the rate is given in miles per hour and the time is given in minutes then change the units appropriately.
It would be helpful to use a table to organize the information for distance problems. A table helps you to think about one number at a time instead being confused by the question.
The following diagrams give the steps to solve Distance-Rate-Time Problems. Scroll down the page for examples and solutions. We will show you how to solve distance problems by the following examples:

OBAN
92
|
| STANRAER
172-------------------------------------112
To read this table you have to draw a vertical from OBAN downward aa horizontal line from the 1st value of STANRAER. The intersection point show the number of miles.
So there are 172 miles & the consumption is 8 mi/gal,. He needs 172/8 gal.
Cost number of gallons needed x price/ gallon
COST = (172/8) x 0.83
COST = (21.5) x 0.83 = 17.845 ≈ $17.85 (1st answer)
Answer:
positive 3/2
Step-by-step explanation:
Answer:
54 three- point field goals
Step-by-step explanation:
184 points = <em>x </em>free throws and 3<em>y </em> three-point field goals
x= 22 free throws, each one is 1 point
184 - 22 = 162
162 ÷ 3 = 54
54=y
54 three point field goals
