The graph shows the girth of the trunk of a fir tree after different numbers of years: line joining ordered pairs 0, 5 and 1,12 and 2, 19 and 3, 26 and 4, 33 and 5, 40 what does the y-intercept of the graph represent? a)the girth increases by 7 centimeters each year. b) the girth increases by 5 centimeters each year. c) the original girth was 5 centimeters. d) the original girth was 7 centimeters.

C) The original girth was 5 centimeters.

Step-by-step explanation:

The y intercept is where it crosses the y axis ( 0,5) and is the initial starting point  of the girth

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
