Answer:
12x+6y+5
Step-by-step explanation:
expand this: 3(4x+2y)=12x+6y
then add 5
12x+6y+5
The equation which relates the mass and length according to the task content is; l = (3/10)m.
<h3>What is the equation of proportionality?</h3>
From the task content, it follows that the proportional relationship is direct. Hence, the constant of proportionality k can be evaluated as follows;
l = k × m
Hence, k = l/m = 9/30 = 3/10.
Therefore, the proportional relationship is given by the equation; l = (3/10)m

Answer:
y = 2x
Step-by-step explanation:
calculate the slope of AB using the slope formula
m =
with (x₁, y₁ ) = A (8, 3) and (x₂, y₂ ) = B (12, 1 )
= = = -
given a line with slope m then the slope of a line perpendicular to it is
= - = - = 2
the equation of a line passing through the origin (0, 0 ) is
y = mx
here m = 2 , then
y = 2x ← equation of perpendicular line
