I think the third one is the answer
Answer:
y = - 10x
Step-by-step explanation:
The equation representing a proportional relationship is
y = kx ← k is the constant of proportionality
y = - 10x ← is the only equation in this form
Thus the equation is y = - 10x with k = - 10
Answer:
the desired line is y = 2x+1
Step-by-step explanation:
A line parallel to y=2x+5 has a very similar equation. All we have to do here is to write y=2x+5 as y=2x+b and find b for x = 1 and y = 3.
Replacing y with 3 and x with 1, we get 3 = 2(1) + b. Then b = 1, and the desired line is y = 2x+1
Answer:
2x(x-3)(-x+1)
Step-by-step explanation:
Factor 2x from everything -> 2x(4x-3-x^2)
Reorder the terms -> 2x(-x^2+4x-3)
Write 4x as a sum -> 2x(-x^2+3x+x-3)
Factor out -x from -x^2+3x looks like -> 2x(-x(x-3)+x-3)
Factor out x-3 from the expression -> 2x(x-3)(-x+1)
