<em>answer \\(x - 4)(3x + 2)  \\ solution \\  {3x}^{2}  - 10x - 8 \\  =  {3x}^{2}  - (12 - 2)x - 8 \\  =  {3x}^{2}  - 12x + 2x - 8 \\  = 3x(x - 4) + 2(x - 4) \\  = (x - 4)(3x  + 2) \\ hope \: it \: helps</em>

A bag contains 5 red marbles, 4 blue marbles, 3 green marbles, and no other marbles. If a marble is chosen at random from the ba
MAXImum [283]

Answer:

A = choosing a red marble

B = choosing a green marble

Probability of A happening = P(A) = 5/(3+5+4) = 5/12

Probability of B happening = P(B) = 4/(3+5+4) = 4/12

Probability of either happening = P(A) + P(B) = 5/12 + 4/12 = 7/12

The key word in their question is red OR green and that is why we add the two probabilities. If they ask the probability of them both happening (if they said red AND green), you would multiply P(A)*P(B).

A town's employment statistics show that 855 of its residents were unemployed last month. This is a decrease of 25% from the pre
Leona [35]
Decrease of 25% means only 855 people? Okay, so you want to backtrack. If you divide by 25% you’re going to get what it was for a 75% decrease. So divide by .75 instead. 855/.75 = 1140 unemployed residents last month

What is the equation of the function in slope-intercept form?
Rasek [7]
To write this equation, you need use the formula y=mx+b.

m represents the slope and b represents the y intercept.

The y intercept is the point where the line touches the y axis. In this case, the y-intercept is 1.

The slope is just rise over run from one coordinate to another. The slope is 2/-1 which could be simplified as -2. The slope just means that we are going up 2 and left 1 to get to a new coordinate.

The equation is y=-2x+1
