Write an equation of the line that passes through (2.5, -3.8 ) and is perpendicular to the line defined by 5x=3 -y. Write the answer in slope-intercept form (if possible) and in standard form (Ax+ By=C) with smallest integer coefficients. Use the "Cannot be written" button, if applicable.

She recorded Dodger's weight during the first two months. The data in the graph show Dodger's weight (in lb), x days after adoption. Weight vs. Days After Adoption Welght (lb) Number of Days (a) Use the points (24, 17.2) and (40, 22) to write a linear model for these data. (b) Interpret the meaning of the slope in context. The slope of 0.3 means that Dodger's weight (Choose one) V during this period. E A pediatrician records the age x (in yr) and average height y (in inches) for girls between the ages of 2 and 10. Height of Girls vs. Age Height (In.) A960") (a) Use the points (5, 44) and (9, 53) to write a linear model for these data. y= 2.25): + 32.75 (b) Interpret the meaning of the slope in the context. The slope of 2.25 means that the average height of girls (Choose one) V during this period. The xed and variable costs to produce an item are given along with the price at which an item is sold. Fixed cost: $3471 Variable cost per item: $23.60 Price at which the item is sold: $27.50 (a) Write a linear cost function that represents the cost C (x) to produce x items. The linear cost function is C(x)= 23.61: + 3471 . (b) Write a linear revenue function that represents the revenue R (x) for selling x items. The linear revenue function is R (x): D. -- _- A lawn service company charges $56 for each lawn maintenance call. The fixed monthly cost of $674 includes telephone service and depreciation of equipment. The variable costs include labor, gasoline, and taxes and amount to $37 per lawn. Part 1 of 5 (a) Write a linear cost function representing the monthly cost C (x) for x maintenance calls. The linear cost function is C (x) = 37X + 674 Alternate Answer: C(x) =37x +674 Part: 1 / 5 Part 2 of 5 (b) Write a linear revenue function representing the monthly revenue R (x) for x maintenance calls. -X The linear revenue function is R (x) = 37x + 674 X 5 Skip Part Check Save For Later Submit AssignWrite an equation of the line that passes through (2.5, -3.8) and is perpendicular to the line defined by 5x: 3- y.
