The initial length of the pine tree=5 feet.
Groth rate of pine tree =3 feet/year.
The initial length of the pine tree =10 feet.
Groth rate of the maple tree =2 feet/year.
After x years, the height of the pine tree= 5+3x feet and
after x years, the height of the maple tree= 10+2x feet.
The inequality for which, after x year, the pine tree is taller than the maple tree is
.
The inequality for which, the pine tree is at least as tall as the maple tree is .
.
Again, after 3x years, the height of the pine tree= 5+3(3x)=5+9x feet and
after 2x years, the height of the maple tree= 10+2(2x)=10+4x feet.
The inequality for which, after 3x years, the pine tree is taller than the maple tree was after 2x years is
The inequality for which, the pine tree is at least as tall as the maple tree is .
Answer:
(3,7) and (-3,-5)
Step-by-step explanation:
To solve the system of equations, graph both functions. The (x,y) point(s) where the functions intersect is the solution(s).
See attached picture.
The fractions already have a common denominator of x-8, so all wee need to do is combine the numerators:
