Which statement is true about polynomial 5s^6t^2 + 6st^9 - 8s^6t^2 - 6t^7 after it has been fully simplified?

 3t²(2st⁷ - s⁶ - 2t⁵)

Step-by-step explanation:

5s⁶t² + 6st⁹ - 8s⁶t² - 6t⁷     5s⁶t² and - 8s⁶t² are like terms which = -3s⁶t² when combined

=          6st⁹ - 3s⁶t² - 6t⁷      next, factor out the GCF of 3t²

=      3t²(2st⁷ - s⁶ - 2t⁵)

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
