EOG Quiz Review

After conducting an experiment in science class, students write the linear model 

𝑤=−0.2𝑑+140 

to represent the weight of an orange, w, in grams, after d days of the orange sitting on a counter. Based on the linear model, which statement is true?

• The orange’s weight is initially 0.2 gram, and the weight decreases by 140 grams for every 1 day that the orange sits on the counter.  

• The orange’s weight is initially 1 gram, and the weight decreases by 0.2 gram for every 140 days that the orange sits on the counter. 

• The orange’s weight is initially 140 grams, and the weight decreases by 0.2 gram for every 1 day that the orange sits on the counter. 

• The orange’s weight is initially 140 grams, and the weight decreases by 1 gram for every 2 days that the orange sits on the counter. 

Consider the linear function represented by the table. Based on the table, what is the rate of change of the linear function? 

(Write answer as a simplified fraciton)

Consider the two parallelograms. Which statement is true?

• The parallelograms are not similar because there is not a sequence of reflections, rotations, translations, and/or dilations that can form parallelogram MNPQ into parallelogram TUVW.

• The parallelograms are similar because parallelogram MNPQ can be dilated by a scale factor of 1/3 about the origin and translated 7 units right to form parallelogram TUVW.

• The parallelograms are similar because parallelogram MNPQ can be dilated by a scale factor of 3 about the origin and translated 10 units left to form parallelogram TUVW.

• The parallelograms are similar because parallelogram MNPQ can be dilated by a scale factor of 1/3 about the origin and translated 6 units left to form parallelogram TUVW.
