An enemy speedboat 400 miles away is running away at a speed of 90 miles per hour to warn the enemy ships about the mines. An Apache helicopter is launched from the deck of the battleship to catch the speedboat. The Apache travels at an average speed of 170 miles per hour. How long will it take to catch the speed boat? Equation 1:
Equation 2:

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
