A group of children are swimming in a pool. They start in the middle of the pool and swim 20 feet toward the right end of the pool. They then swim to a point x feet to the right of the middle of the pool. So far, the children have swum a distance of 45 feet. Formulate an absolute value equation to represent this situation. Then solve the equation. a. 45 = 2|20- x; x = 5 or x= 45
b. 45 = 20+2|20 – x|; x=45
c. 45 = 20+ |20 – x|; a. x = 45
d. 45 = 20 – |20 – x|; x = 5 or x = 45

b. f(x) = –√x + 3this is the correct answer

question

given the diagram below, what is md?

the sum of the interior angles is 360°

take away from 360 the sum of the knows angles and you will have the angle d.

360 - 108 - 108 - 72 = 72°

the linear relationship that represents a variation in direct proportion is the linear function that varies according to the numbers of its domain, for example the cost of producing x number of items can be represented in direct proportion by f (x) = mx + b, where m is the constant of proportionality, x the number of articles produced and b the fixed cost
