In π = 7x - 2y we first isolate y by adding 7x on both sides.
This gives us π + 7x = -2y. Divide 2 on both sides, then we are left with:
y =
I hope this is what you were looking for.
Answer:
Step-by-step explanation:
Answer:
fraction x=7/5
mixed number x= 1 2/5
decimal x=1.4
Step-by-step explanation:
a)
h(t) , namely "h" variable is being represented in terms of "t".
h = dependent variable, depends on the value of "t", output.
t = independent variable, takes on values freely, input.
b)
![\bf \stackrel{\stackrel{h(t)}{t=1.4}}{h(1.4)} = \stackrel{h=12.8}{12.8}~~ \begin{cases} t=1.4~~&\textit{after 1.4 seconds}\\ h=12.8~~&\textit{the ball is 12.8 meters up} \end{cases}](https://tex.z-dn.net/?f=%5Cbf%20%5Cstackrel%7B%5Cstackrel%7Bh%28t%29%7D%7Bt%3D1.4%7D%7D%7Bh%281.4%29%7D%20%3D%20%5Cstackrel%7Bh%3D12.8%7D%7B12.8%7D~~%20%5Cbegin%7Bcases%7D%20t%3D1.4~~%26%5Ctextit%7Bafter%201.4%20seconds%7D%5C%5C%20h%3D12.8~~%26%5Ctextit%7Bthe%20ball%20is%2012.8%20meters%20up%7D%20%5Cend%7Bcases%7D)
c)
![\bf h(2)=-5(2)^2+14(2)+3\implies h(2)=-20+28+3\implies h(2)=11](https://tex.z-dn.net/?f=%5Cbf%20h%282%29%3D-5%282%29%5E2%2B14%282%29%2B3%5Cimplies%20h%282%29%3D-20%2B28%2B3%5Cimplies%20h%282%29%3D11)
after 2 seconds, the ball is 11 meters high up.
