Abirch tree that is 4 ft tall grows at a rate of 1 ft per year. a larch tree that is 6 ft tall grows at a rate of 0.5 ft per year.
let the variable t represent time in years and h represent height in feet. in how many years will the trees be the same height?
which system of equations can be used to solve this problem?
a.{h=4-t
{h=6-0.5t
b.{h=5t
{h=6.5t
c.{h=1+4t
{h=0.5+6t
d.{h=4+t
{h=6+0.5t

If its non of them tell me..valerie took a day-trip. she drove from her house for a while and took a coffee break. after her coffee break, she continued driving. after  2  hours of driving after her coffee break, her distance from her house was  210  miles. her average speed during the whole trip was  60  miles per hour. valerie created the equation  y−210=60(x−2)  to represent this situation, where  xx  represents the time in hours from her coffee break and  yy  represents the distance in miles from her house. which graph correctly represents valerie's distance from her house after her coffee break?
