A. (x, y) --> (1.5 - x, 1.5 - y)

A figure is graphed on a coordinate plane with (x, y) representing the location of a point on the figure. The figure is transformed using the rule (x, y) --> (ax, ay). Which statement is true?

D. If a is between 0 and 1, the image of the figure is smaller than the figure.

A. If a is greater than 1, the image of the figure is congruent to the figure.

B. If a is between 0 and 1, the image of the figure is congruent to the figure.

C. If a is greater than 1, the image of the figure is smaller than the figure.

Which statement best represents the inequality, 4x – 10 > 6x – 20?

C. A waiter makes $4 in tips for every table he helps and is required to give $10 to the hostess at the end of his shift. A waitress at a different restaurant earns $6 in tips for every table she helps and is required to give the hostess $20 at the end of her shift. The waiter will make more money after x tables are helped.

A. Yesenia spent $6 for each nail polish, plus $20 on a pair of sandals. The next day she spent $4 for each nail polish, plus $10 on a pair of socks. Yesenia spent more money on the first day after buying x nail polishes.

B. The seed of a plant A is buried 10 centimeters underground and grows at a rate of 4 centimeters per week. The seed of plant B is buried 20 centimeters underground and grows at a rate of 6 centimeters per week. Plant A will be shorter than plant B after x weeks.

Which of the following best represents the equation, 3x + 6 = 1.5x + 12?

Bucket A is 6 liters full of liquid and is being filled at a rate of 3 liters per minute. Bucket B is 12 liters full of liquid and is being filled at a rate of 1.5 liters per minute. Both buckets will have the same amount of liquid after x minutes.

Bucket A is 6 liters full of liquid and is being emptied at a rate of 3 liters per minute. Bucket B is 12 liters full of liquid and is being emptied at a rate of 1.5 liters per minute. Both buckets will be empty after x minutes.

Bucket A is 6 liters full of liquid and is being emptied at a rate of 3 liters per minute. Bucket B is 12 liters full of liquid and is being emptied at a rate of 1.5 liters per minute. Bucket A will be emptied before Bucket B, after x minutes.

Bucket A is 6 liters full of liquid and is being filled at a rate of 3 liters per minute. Bucket B is 12 liters full of liquid and is being filled at a rate of 1.5 liters per minute. Bucket A will have less liquid after x minutes.

The slope of line CA is $$-\frac{3}{2}$$ . Which of the following is true about the slope of line XZ?

The slope of line XZ is the same as the slope of line CA because the ratios of the corresponding sides of the triangles are equivalent.

The slope of line XZ is the negative reciprocal of the slope of line CA because the triangles are flipped.

The slope of line XZ is one-half the slope of line CA because the ratio of corresponding sides between the triangles is $$\frac{1}{2}$$ .

The is no relationship between the slope of line XZ and the slope of line CA.

Triangle HJK and triangle PMK are similar right triangles. The coordinates of all the verticces are integers. Which statement is true about the slope of line HK and the slope of line PK.

The slope of line HK is equal to the slope of line PK because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is the same for line HK as it is for line PK.

The slope of line HK is less than the slope of line PK because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is less for line HK than it is for line PK.

The slope of line HK is greater than the slope of line PK because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is greater for line HK than it is for line PK.

The relationship between the slope of line HK and the slope of line PK cannot be determined because the traingles are congruent.
