Y=-4x+3 is already in slope intercept form. Graphed it looks like this
I say y=300(2x) X=hours Y=population
Y=600x
You have a 50% chance of getting a blue marble and a 50% chance of getting a yellow marble
Given problem is
To simplify that we need to multiply and divide by conjugate of the denominator
conjugate of denominator 6+i will be 6-i as we just need to change sign of the imaginary part
Now multiply and divide by 6-i
Hence final answer is
X= 12.5, this is because you need to add 25 to the other side of the equation to make 2x = 25 and then divide both sides by 2 to get x=12.5
