Step-by-step explanation:
Let x = the number of years since the first year and let y = the total number of plants.
Roses: y = 5 + 2x
Tulips: y = 20 – 3x
You can use elimination to solve.
y = 5 + 2x
(-)y = 20 – 3x
0 = -15 + 5x
15 = 5x
3 = x
This means that 3 years after the first year, the number of rose bushes equals the number of tulip plants.
The graphs appear to
intersect at (3, 11) which verifies that x=3
Answer:
(3, 6)
Step-by-step explanation:
You add the x points together and divide by two, then you add the y points together and divide by 2.
Answer:
Step-by-step explanation:
you need to use the proportions
x=(3*5)/8=15/8
