Sam was asked to evaluate the expression 5x+3x+20 for x = 100. sam's work shown below. sam's work: 5x+3x+20 = 100 8x+20 = 100 8x = 80 x = 10 what mistakes did sam make? sam to answer the question correctly.

Use the graph of the sine function y=2sinθ shown below

Adoctor administers a drug to a 38-kg patient, using a dosage formula of 50 mg/kg/day. assume that the drug is available in a 100 mg per 5 ml suspension or in 500 mg tablets. a. how many tablets should a 38-kg patient take every four hours? b. the suspension with a drop factor of 10 ggt/ml delivers the drug intravenously to the patient over a twelve-hour period. what flow rate should be used in units of ggt/hr? a. the patient should take nothing pills every four hours. (type an integer or decimal rounded to the nearest hundredth as needed.)

Abcd is reflected across the x- axis, then rotated 90 clockwise about the orgin, and finally reflected across the line y= x to form a’ b’ c’ .
