Are these proportional? And I need to show work sooo for example on the first question we did in class we wrote down -3/1
-6/2=-3/1
-9/3=3/1

I hope I’m not asking for too much but I want to start off my trimester strongly.

Step-by-step explanation:

If y is proportional to x,

y ∝ x

y = kx

k =

Here, k = Proportionality constant

For y = -8 and x = -4,

k =

k = 2

For y = -4 and x = -2

k =

k = 2

For all values of x and y proportionality constant = 2.

For x = 0 and y = 0,

If we graph a line passing through these points, the line will pass through the origin (No y-intercept).

And we know that any line passing through the origin represents the proportional relation between x and y variables.

Therefore, given table represents the proportional relation.

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
