Answer:
y = -2x +8
Step-by-step explanation:
The 2-point form of the equation of a line is useful when two points are given.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (2 -4)/(3 -2)(x -2) +4
y = -2(x -2) +4
y = -2x +8
If I remember correctly, the solutions are only on the solid line or in the shaded area? therefore Answers could be:
6.) (-3,0.5) (-4,0) (-2,0) (-2,-5) (-3,-5) (-4,-1) (-3,-1) (-2,-1)
7.) (-1,0) (-2,0) (-3,0) (0,-1) (-4,-1)
The answer is 21x-25 because all you have to do is multiply the 1/4 by the 84x and then multiply 1//4 by negative 100. A simpler way of explaining this is just that you need to distribute
By taking the quotients between the areas, we see that:
<h3>
How to find the probabilities?</h3>
First we need to find the areas of the 3 shapes.
For the triangle, the area is:
T = 3*5/2 = 7.5
For the blue square, the area is:
S = 3*3 = 9
For the rectangle, the area is:
R = 10*6 = 60
Now, what is the probability that a random point lies on the triangle or in the square?
It is equal to the quotient between the areas of the two shapes and the total area of the rectangle, this is:
P= (7.5 + 9)/60 = 0.275
b) The area of the rectangle that is not the square is:
A = 60 - 9 = 51
Then the probability of not landing on the square is:
P' = 51/60 = 0.85
