When figuring out the amount of mulch would be needed for alex's back yard, he created an equation that
approximates the number of bags, b, he'll use. if his equation is b = 4(2x +7)+3(2x +7) and (2x+7) is
equal to 2, how many bags will he need? show your mindful manipulations.

What is the measure of ac? 5 units 13 units 26 units 39 units 3x- 2b 6x + 9

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)

Ab and bc are tangent to circle d. find x is ab = 3x + 8 and bc = 26. find x
