Answer 2

Answer: From c to the midpoint the coordinates have changed from (-1;9) to (-9;-10). So the difference is (-9-(-1); -10-(9)) that equals (-8;-19). And you should add (-8;-19) to the coordinates of the middle point (-9;-10). So we get (-9+(-8); -10+(-19)) that is (-17;-29). This is the endpoint of d. Answer: d (-17;-29).

You sell hotdogs for $1.25 each. Which equation can you use to find how many hotdogs you sold if you $60 from selling hotdogs?

Answers

To find the number of hotdogs sold, you can use the equation: 1.25x = 60, where x represents the number of hotdogs sold.

Answer: 1.25x=60
Divide 60 by 1.25 to get x alone and you'll have 48 hotdogs. To check, multiply 48 by 1.25 and you'll get 60.

The graph shows the data points in the table and the exponential regression model associated with the data. A 2-column table with 5 rows. The first column is labeled days after treatment with entries 2, 4, 6, 8, 10. The second column is labeled number of weeds with entries 100, 26, 6, 2, 1. A graph shows days after treatment labeled 1 to 11 on the horizontal axis and number of weeds on the vertical axis. A line shows a downward trend. Based on the graph of the regression model, which is true? The number of weeds is decreasing by a multiplicative rate. The number of weeds is increasing by a multiplicative rate. The number of weeds is decreasing by an additive rate. The number of weeds is increasing by an additive rate.
