3(x + 4) = x/2 - 8
First, we can multiply both sides by 2:
6(x+4) = x - 16
6x + 24 = x - 16
Isolate x:
5x = -16 - 24
5x = -30
x = -6
Answer:
see below
Step-by-step explanation:
Part A
Notice that for each increase of 1 in x, there is an increase of 3 in y
There is a correlation between the amount of sunlight and the height of the plant
Part B
The slope in change in y over change in x
m = 3/1 = 3
y= mx+b
y = 3x+b
The y intercept is when x =0 so b = 4
y = 3x+4
Part C
With no sunlight the plant is 4 cm tall. As the plant gets more sunlight, the plant grows at 3 cm per hour of sunlight.
Answer:
(-7,23)

Answer:
Perpendicular lines have slope that are negative reciprocals.
The slope of the perpendicular line is M = -1/3.
Step-by-step explanation:
(4,-1) --> X = 4, Y = -1, M = -1/3
y = Mx + b
-1 = (-1/3)*4 + b
-1 = (-4/3) + b
-3/3 = (-4/3) + b
-3 = -4 + 3b
1 = 3b
b = 1/3
y = (-1/3)X + 1/3
