Answer:
3y+4
Step-by-step explanation:
9y-6y=3y
Teresa counted 2 leaves on May 1st and 9 leaves on September 1st.
The difference in the number of leaves is:
9 - 2 = 7
Hence, the number of leaves has increased by 7 units.
Sinx = cosb => x + b = 90 <=> b = 90 - 47 = 43o
Get y by itself...
y= -(jV-82)/(V-61)
