Answer:
x= 1
Step-by-step explanation:
-7x +2(-7x +8) = -5
-7x -14x +16= -5
-21x +16 = -5
-21x = -21

hope this helps :))
The slope of the line is 3 because 9 divided by 3 is 3
W being width and L being length,
w + l is less than or equal to 10
It would take exactly 4 years for these trees to be the same height.
Step-by-step explanation:
Given,
Height of Tree A = 9 feet
1 feet = 12 inches
9 feet = 9*12 = 108 inches
Growth rate = 2 inches per year
Let,
y be the number of years.
A(y)= 108 + 2y
Height of Tree B = 8 feet
8 feet = 8*12 = 96 inches
Growth rate = 5 inches per year
B(y)=96+5y
In case of same height;
A(y)=B(y)
Dividing both sides by 3
It would take exactly 4 years for these trees to be the same height.
