Y=-3x+1
So the answer is A. All you're doing is moving the 3x to the opposite side, and because your switching the side, you need to switch the sign. So it's a negative 3x after you solve for y. Solving for y(or any letter) is just getting that letter alone on one side of the equal sign.

Factor the GCF: −6x4y5 − 15x3y2 + 9x2y3 (5 points)
nadezda [96]
*Hint: Before you try to factor anything, you try to see if they have a common factor.

Since -3 is a common factor, everything is divided by -3.

-6x^4y^5 - 15x^3y^2 + 9x^2y^3
-3(2x^4y^5 + 5x^3y^2 - 3x^2y^3)

Since you can still divide by x^2y^2, you do so.
-3x^2y^2 (2x^2y^3 + 5x - 3y)

Petra lives in russia. what is the probability that she works and attends school?
Olegator [25]
Is there more to this question? I feel like there is not enough information. Perhaps the probability is low because in order to survive, she must work. Many jobs may not require schooling. Sorry if this didn’t help.

Average rate of change [1,3] = (15.882 - 11.38)/(3-1) = 4.502 /2 = 2.251


average rate of change [-4,-2] = (0.0971- 0.0018)/(-2+4) = 0.0953 /2 = 0.04765

average rate of change [1,3]  / average rate of change [-4,-2] 
= 2.251 / 0.04765
= 47.24

47.24
