Answer:
Step-by-step explanation:
Given
A roll of cube numbered 1 - 4
A flip of coin
Required
Determine the possible outcomes for a number greater than 3
First, we list the sample space of the coin:
Next, we list outcomes greater than 3
Next, we list out the sample space (C) of a flip of coin:
Where
So, the possible outcome for a number greater than 3 is:
The given points are:
(-2,1) and (-3,2)
The x-coordinate of the midpoint can be calculated as follows:
Xmidpoint = (x1+x2) / 2
Xmidpoint = (-2-3) / 2 = -2.5
The y-coordinate of the midpoint can be calculated as follows:
Ymidpoint = (y1+y2) / 2
Ymidpoint = (1+2) / 2 = 1.5
Therefore, the midpoint of the segment is (-2.5 , 1.5)
Comparing this with the choices, we will find that the correct choice is D
{x=-1/3-10/3y
5x+20y=5
5(-1/3-10/3y)+20y=5
solve the equation
.
.
Y=5
substitute the value of y into the equation
x=-1/3-10/3×2
.solve the equation
.
.x=-7
(x,y)=(-7,2)
{3×(-7)+10×2=-1
5x(-7)+28×2=5
simplify
{-1=-1
5=5
the ordered pair is asolution
(X,Y)=(-7,2)
That's all!!!!
Answer:
b is the right answer
Step-by-step explanation:
First you distribute the -12 to the (x+5) getting 144=-12x-60.
Next you add 60 to each side getting 204=-12x
Then you divide each side by -12 getting -17=x, which is the answer.<span />
