Answer:
(-1.5,0.75)
Step-by-step explanation:
If you graph it you can see the vertex
<span>F for Frank, A or Alice.
F(initial)=1.95 inches
A(initial)=1.50 inches
Frank's equation at .25 inches per year and t representing year variable.
F=1.95+.25t
Alice's equation at .40 inches per year and t representing year variable.
A=1.5+.40t
To figure out how old they will be when their beaks are the same lengths set the equations equal to eachother as the equations are length.
1.95+.25t=1.5+.40t
.45=.15t
t=3 years</span>
11z/16+7z/8=5/16
(11z+14z)/16=5/16
25z=5
z=5/25=1/5
Answer:
around 1.36
