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.
If

Answer:
16/y is your answer. Hope this helps
Step-by-step explanation:
m< 1 = 90
Given m<1 = 4y - 2
4y - 2 = 90
4y = 92
y = 23
Answer is the third option
y = 23
I assume you're looking for the value of x?
Combine like terms: 8x+5x+2x-11+6=180 -> 15x-5=180
Add 5 to both sides: 15x=185
Divide both sides by 15: x=12 1/3
So x is 12 1/3 or 37/3
Hope this helped!
