0
Step-by-step explanation:
If you divide 45 by 9 you will get the value of m, which is 5
Answer:
y =2.5
Step-by-step explanation:
1.4y = 3.5
Divide each side by 1.4 to isolate y
1.4y /1.4 = 3.5/1.4
y =2.5
Answer:
Four unique planes
Step-by-step explanation:
Given that the points are non co-planar, triangular planes can be formed by the joining of three points
The points will therefore appear to be at the corners of a triangular pyramid or tetrahedron such that together the four points will form a three dimensional figure bounded by triangular planes
The number of triangular planes that can therefore be formed is given by the combination of four objects taking three at a time as follows;
₄C₃ = 4!/(3!×(4-3)! = 4
Which gives four possible unique planes.
