The relationship between the years since the tree was transplanted and its height in inches is linear and represented graphically by a line with positive slope and positive y-intercept
Step-by-step explanation:
Their is a linear relation between the years since the tree was transplanted and its height in inches because
- The tree has a constant rate of increasing of its height per year
- Assume that the initial height of the tree when it planted is b inches
- Its height increases m inches per year
- Its height (y) after x years can be expressed in the formula y = m x + b
y = m x + b is the form of the linear equation, where
- m is the slope of the graph of the equation
- b is the y-intercept (value y at x = 0)
The relationship between the years since the tree was transplanted and its height in inches is linear represented graphically by a line with positive slope and positive y-intercept

Answer:
(-2, 1).
Step-by-step explanation:
When f(x) = 0
4 + 2x = 0
2x = -4
x = -2.
Ehen f(x) = 6
4 + 2x = 6
2x = 6-4 = 2
x = 1.
Answer:
Area of the square:
12 x 16 = 192
Area of the semi circle on top:
16 - 8 = 8 is your diameter
half of 8 is 4.
I got 8 from adding the two fours on the side of that semi circle on top.
4^2 x 3.14
16 x 3.14 = 50.24
50.24 divided by 2 = 25.12
Area of the semi circle on the side:
12 - 8 = 4
4 is your diameter and half of that which would be your radius is:
2 so
2^2 x 3.14
4 x 3.14 = 12.56
12.56 divided by 2 = 6.28
Now we are going to add all the areas:
192 + 25.12 + 6.28 = 223.4 is your answer
The value of x is 13
<h3>How to determine the value</h3>
From the diagram shown, we have that the line segments as;
NK = NM + ML + LK
Where;
- NK = 23
- NM = x - 6
- ML = 9
- LK = 2x - 19
Substitute the values into the equation
(x - 6) + 9 + 2x - 19 = 23
collect like terms
x + 2x -6 + 9 - 19 = 23
Add like terms
3x - 16 = 23
3x = 23 + 16
3x = 39
Divide both sides by 3
x = 39/ 3
x = 13
Thus, the value of x is 13
