Step-by-step explanation:
$3.68 for 16 pens
$3.68 per 16 pens
($3.68) / (16 pens)
$0.23 / (1 pen)
$0.23 / pen
$0.23 per pen
Distance, d, is directly proportional to the number of gallons of gas, g. Thus,
d α g
To turn alpha to equal sign, we insert a constant of proportionality, k.
d=kg
To find k, we use the given conditions.
476 = k (14)
k = 34
Therefore, the equation is,
d = 34g
and for travelling 578 miles,
578 = 34g
g = 17 gallons is needed.
Answer:
y=(x+1)(x-1)(x+8)
Step-by-step explanation:
When creating a factor with a known zero, use (x-ZERO)
For instance: a zero of -1 would be reprsented as (x+1)
