1. A tank has 25 gallons of chemicals in it. Chemicals were added to the tank at a rate of 7
gallons per second. Which equation models the relationship between t the number of
gallons of chemicals, and w, the number of seconds chemicals are being added to the
tank?
A T = 25w +7
B. T= 32W
C. T=W + 32
D. T = 7w + 25

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
