Answer:
Y intercept of this function is 2 which is the height of a plant at the time x = 0 or the height of a plant when kept in sunlight.
Step-by-step explanation:
In the given function y = (2 + 4x), x is the number of hours a plant kept in sunlight and y is the height in mm.
Since this equation is in the form of equation of straight line y = mx +c in which m denotes gradient of the line and c is y intercept.
In y = 4x + 2, y intercept of the equation is 2 which means when a plant was kept in sunlight its height was 2 mm.
The graph of the solution to this inequality is: C. number line with an open circle plotted at negative eight and arrow pointing left.
<h3>What is a number line?</h3>A number line simply refers to a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.
Next, we would solve the given inequality as follows:
−0.4b + 2.4 < 5.6
Subtracting 2.4 from both sides, we have:
−0.4b + 2.4 - 2.4 < 5.6 - 2.4
−0.4b < 5.6 - 2.4
−0.4b < 3.2
Dividing both sides by -0.4, we have:
b < -3.2/0.4
b < -8
In conclusion, the circle on a number line should be open and would point to the left when the inequality symbol is <.
