D. for no values of p

if r and s are numbers on a number line, the best representation of how much farther one value is from zero than the other value is

A. (r+s)

B. (r-s)

C. (r) + (s)

D. (r) - (s)

() represent the absolute value sign

the Point (-3,-4) lies on the graph of y+ f(x). This corresponding point that must lie on the graph of

y= l f(x)l is

a. (3,4)

A hot air balloon pilot raises a balloon 200 m from the ground, turns off the burner and allows the balloon to decend 60 m before turning the burner on again to raise it another 170 m.

A. use +/- values to determine the total distance the balloon travelled.

B. use absolute values to determine the total vertical distance travelled by the balloon.

The maximum and minimum length, l, of an 8 ft board with a tolerance of -1/4 and +1/4 in can be determined by solving the equation

(L-0.25)= 96

(L+0.25)= 96

(L-96)= 0.25

(L+96)= 0.25

the brackets symbolize the absolute value sign

An equation that describes the maximum and minimum temperatures at which a chemical compound is in a liquid state is given by the absolute value equation (t-50)=50, where T is the temperature in degrees Celsius. Calculate the range in temperature, and identify the chemical compound.

state the domain and range of  $y=\left|-4.9t^2+8.5t-2.23\right|$y=|−4.9t²+8.5t−2.23| 

the winning margin between the top two candidates in an election can be represented by

 $\left|A+B\right|$|A+B| 

 $\left|A-B\right|$|A−B| 

 $\left|A\right|+\left|B\right|$|A|+|B| 

 $\left|A\right|-\left|B\right|$|A|−|B| 

Ahmed worked all summer for a bee farmer. Ahmed was paid $400.00 the first week. The farmer paid a $50.00 raise per week for each additional week of employment. Ahmed worked on the bee farm for 8 weeks before his first year of university began.

The money Ahmed earned over the summer was used for miscellaneous expenses at university. At the start of the ninth week of school he had $3 000.00 in his bank account. How much money did Ahmed spend each week?

The school year is approximately 32 weeks long. Will Ahmed have enough money if he continues to spend his savings at the same rate?
