Answer:
Step-by-step explanation:
x + 3 y = 1 ----------------(I)
-3x - 3y = -15 -------------(II)
Add the equations and y will be eliminated and we can find the value of x
(I) x + 3y = 1
(II) <u>-3x -3y = - 15</u> {Now add}
-2x = - 14
x = -14/-2
x = 7
Plugin x =7 in equation (I)
7 + 3y = 1
3y = 1 - 7
3y = -6
y = -6/3
y = -2
Answer:
B. W,V,Z
Step-by-step explanation:
Collinear points are two more points in the same plane that lie in a straight line.
From the diagram, Z is the intersection of the two diagonals of quadrilateral VXWY.
The points V, Z and W lie along the same diagonal, hence they are collinear.
The point y, Z, and X also lie along the same diagonal, these are also collinear.
The correct choice is B
Answer:
If we know the area of the circle we can find the radius by using the formula for
Area = πr²
The answer is A. 1/(3x+1)
Addition because you add them together to find the total
