<span>The sample space of the rolling the cube is 6.
 The probability of rolling 2 in a cube is 1. So p(2) is 1/6
Similarly the probability of rolling 5 in cube is 1.
 So, p(5) = 1/6
To find p (2 or 5) which is p(2) + p(5)
p(2) + p(5) = 1/6 + 1/6 which is 2/6.
2/6 can be reduced to 1/3.
  so right answer is 1/3</span>

Which is an equation in point slope form of the line that passes through the points (7 -8) and has a slope of -3
Nataly [62]
Y+8 = -3(x-7)
Distribute the -3
y +8 = -3x +21
Subtract 8 from both sides
Y = -3x +21 -8
Y= -3x+13

Please help me with this
Fudgin [204]

The perimeter of the rectangle is 2(2x+5), and the perimeter of the triangle is x+7+x+4+x+11, which simplifies to 3x+22.

Therefore...

3x+22=4x+10

x=12

The perimeter of the rectangle is 2(2(12)+5)=2(24+5)=2(29)=48.

a. x=12

b. The perimeter of each figure is 48.

Answer:

To find the value of y from a given value of x, find the position of x on the x-axis, then trace vertically until you meet the line.  Once you meet the line, trace horizontally to the y-axis to find the corresponding value of y.

To find the value of x from a given value of y, find the position of y on the y-axis, then trace horizontally until you meet the line.  Once you meet the line, trace vertically to the x-axis to find the corresponding value of x.

From inspection of the graph,

when x = 1,  y = -1

when x = 0, y = 2

when x = 2, y = -4

Therefore,

\begin{array}{| c | c |}\cline{1-2} x & y\\\cline{1-2} 1 & -1 \\\cline{1-2} 0 & 2 \\\cline{1-2} 2 & -4 \\\cline{1-2}\end{array}

To find the equation of the line, find the slope:

\sf slope\:(m)=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{2-(-1)}{0-1}=-3

Then use one of the points and the found slope with the point-slope form of a linear equation: y-y_1=m(x-x_1)

\implies y-2=-3(x-0)

\implies y=-3x+2

So the equation of this line is: y=-3x+2
