Recall that you algebraically find the intersection point of two lines by setting their equations equal to each other and solving for the x-coordinate of intersection. Then substitute to find the y-coordinate. Algebraically determine the intersection point of y= 0.5x + 14 and y= 2x + 8

Look at the following graph of the given equation. determine whether the equation is a function. explain why or why not.

Ariana starts with 100 milligrams of a radioactive substance. the amount of the substance decreases by 20% each week for a number of weeks, w. the expression 100(1−0.2)w finds the amount of radioactive substance remaining after w weeks. which statement about this expression is true? a) it is the difference between the initial amount and the percent decrease. b) it is the difference between the initial amount and the decay factor after w weeks. c) it is the initial amount raised to the decay factor after w weeks. d) it is the product of the initial amount and the decay factor after w weeks.
