The relationship between revenue generated and the number of full-time employees for a particular company can be approximated by 20nplus36Requals3500, where R is revenue in millions of dollars and n is the number of employees. In 2015, the rate of change of revenue with respect to time was $858 million per year; find the rate of change of the number of employees with respect to time.

step-by-step explanation:

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

we can set up an equation to find the girls' ages. the equation is         28=0.5x-5+x. (comment if you need me to explain how i got this equation.) so, you add x and 0.5x to get 1.5x and add 5 to each side. your new equation is 33=1.5x. now divide both sides of the equation by 1.5 to get 22=x. because x is mary's age, to find jasmine's age we subtract mary's age from 28. we find that mary is 22 years old and jasmine is 6 years old.
