Soro bought a $50.00 bus card at the beginning of the week. each bus ride costs $2.50. he needs to have at least $20.00 on
his card at the end of this month. to determine how many bus rides he can take between now and the end of this month, soro
wrote and solved the following inequality:
50 - 2.5x_> 20
-2.5x_> -30
x_> 12
what error, if any, did soro make when writing or solving this inequality?
a: soro's original inequality should have been 50-2.5x5 20.
b: soro should have added 2.5 to each side for his first step.
c: soro should have reversed the inequality symbol when using the division property of inequality.
d: soro's work shows no errors.

After a dreary day of rain, the sun peeks through the clouds and a rainbow forms. you notice the rainbow is the shape of a parabola. the equation for this parabola is y = -x2 + 36. graph of a parabola opening down at the vertex 0 comma 36 crossing the x–axis at negative 6 comma 0 and 6 comma 0. in the distance, an airplane is taking off. as it ascends during take-off, it makes a slanted line that cuts through the rainbow at two points. create a table of at least four values for the function that includes two points of intersection between the airplane and the rainbow. analyze the two functions. answer the following reflection questions in complete sentences. what is the domain and range of the rainbow? explain what the domain and range represent. do all of the values make sense in this situation? why or why not? what are the x- and y-intercepts of the rainbow? explain what each intercept represents. is the linear function you created with your table positive or negative? explain. what are the solutions or solution to the system of equations created? explain what it or they represent. create your own piecewise function with at least two functions. explain, using complete sentences, the steps for graphing the function. graph the function by hand or using a graphing software of your choice (remember to submit the graph).
