Answer:
0 => -⅘ => 1.5 => 3 => -4 =>
Step-by-step explanation:
The greater the absolute value of a slope, the steeper the slope. By absolute value, we mean the non-negative value of tthe .
To arrange the slope values, from the least steep to the steepest, ignore the negative sign in any of the slope values.
Thus, in the order from the least steep to the steepest, we have:
0 => -⅘ => 1.5 => 3 => -4 =>
The greater the absolute value of the slope, the greater the vertical movement. The greater the vertical movement, the steeper the slope.
A slope value of 0 connotes a horizontal line.
Answer:
The travel size costs 6 % as much as the regular size. Thus the regular size would be more economical and thus a better buy
Step-by-step explanation:
step 1
<em>Find out the unit rate of a regular tube of toothpaste</em>
we know that
To find out the unit rate, divide the total cost by the total weight
so
step 2
<em>Find out the unit rate of a travel size tube of toothpaste</em>
we know that
To find out the unit rate, divide the total cost by the total weight
so
step 3
Find out the percent of increase
we have that
The unit rate represent the 100%
so by proportion
Find out what percentage represent the difference ($0.83-$0.78=$0.05 per ounce)
therefore
The travel size costs 6 % as much as the regular size. Thus the regular size would be more economical and thus a better buy
