meters per minute and the unit rate for Mark
Assuming that Tony and Mark both walk at a constant rate, the unit rate for Tony Is
is
meters per minute.
On a graph, the line representing Tony's distance covered with respect to time would be
walking speed is
Mark's.
Mark's line. So, Tony's

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

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.

step-by-step explanation:

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
