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.
Answer:
y=-3x-5

explanation is showed above
Answer:
7040
Step-by-step explanation:
C= 2000
B = 20/100 x 2000 = 400 + 2000 = 2400
A= 10/100 x 2400 = 240+2400= 2640
2000 + 2400 + 2640 = 7040
