Remember that the y-intercept is obtained when the value of x is set to zero. This means that the y-intercept is the value of the height without sunlight yet. This also refers to the original height of the plant. This gives:
y = 4 + 2(0) = 4
So, the original height of the plant is 4 mm.
The formula also indicates that when sunlight is present, a height of 2mm is increased every hour of sunlight exposure.
Answer:
59 adults and 102 kids

Answer:
192
Step-by-step explanation:
The sum of the first 3 terms of the A. P is
a + a + d + a + 2d = 18, that is
3a + 3d = 18 ← substitute a = 4
12 + 3d = 18 ( subtract 12 from both sides )
3d = 6 ( divide both sides by 3 )
d = 2
Thus the first 3 terms are
4, 6, 8 and their product = 4 × 6 × 8 = 192
Solving for a variable means to rewrite the equation so that the desired variable is alone on one side. So, we have to "move" all the other variables/constants in order to make this happen. We are allowed to add/subtract the same quantity from both sides, or to multiply/divide both sides by any non-zero number.
Let's start with the first example: we are given
11. 
the variable 
is not alone on the right hand side because it is multiplied by 
. We can reverse this by dividing both sides by : the equation becomes
So, we have written the equation as 
, which means that now sits alone on one side of the equation, and thus we have solved the equation for !
Similarly, we do all the others:
12. 
Subtract 
from both sides to get
13. 
Subtract 
from both sides to get
Now divide both sides by 
to get
14. 
Multiply both sides by 2:
Divide both sides by 
:
