Answer:
Step-by-step explanation:
Amount by which the plant gre in one month = 9.5 - 8.75 = 0.75
Amount by which it will grow in x months = x * 0.75
The hegiht of the plant after 6 months = amount it will grow by in 6 months + current heigt = 0.75x + 8.75
Hence answer is
d
Find the soluiton
2x+2y=16
3x-y=4
x+y=8
<u>3x-y=4+</u>
4x=12
x=3
3(3)-y=4
9-y=4
y=5
(3,5)
test them to see if get true statment
obviously the first equatons of 1,2,4 work
1 doesn't work
2, works
4. doesn't work
2 is the same as the first except both euations are just doubled
answer is 2
