For the first one your equation is h(d)=3/7d+5
If d represents the number of days and the question is wanting to know the height after 1 week (7 days) then you would get this equation once 7 is in the place of d
h(d)=3/7(7)+5
When solved you answer is 8 inch.
For the second one your equation is f(x)=75x+250
If x represents the number of weeks and the question is asking how much money Sam will have after 12 weeks then you will get this equation once putting in 12
f(x)=75(12)+250
Once solved you will get the answer $1150
Hope this helps! :)
13 vehicles (at least) will be needed to transport the students. 18x3= 54+10= 64\5= 12.8. Round 12.8 to the nearest while number is 13
Y=2x+10
That is the eqasion, 2(it is the cost per card) and multpy be how many cards you want, then add 10 as base fee
I'm pretty sure it's d. y=-3x
