Step-by-step explanation:
=(y-y1)=Y2-Y1/X2-X1(X-X1)
7+3 = 10 total marbles
1st pick = 7/10 for a red one
2nd pick = 6/9 reduces to 2/3 for a red one
3rd pick = 3/8 for a white one
7/10 x 2/3 =14/30 reduces to 7/15
7/15 x 3/8 = 21/120 reduces to 7/40
probability = 7/40
Answer:
d = 5
Step-by-step explanation:
We want to know what d would be when x = -1, so we can start off by plugging in -1 for x to get the following equation: 
. On the left hand side, 2 negatives become a positive sign, so the -(-1) becomes a +1, and 8+1 would equal 9. On the right hand side, we just multiply 2 and -1 to get -2. So, the equation now looks like this: 
. We know that 
= 3, so we would get 3 = d-2. THen we would add 2 to both sides to get d = 5. Hope this helps!
Answer:
c
Step-by-step explanation:
The minimum and the x intercept are the same point.
Your answer is the second best answer. The definition of an x intercept is the point on a graph where y = 0. In this case, the graph begins to move in the opposite direction from the direction it was moving.
And so the x intercept just touches the x axis. Good enough. It is still classified as the x intercept because y = 0.
They are not IN a quadrant, but they all border the second quadrant.
