Step-by-step explanation:
3y/3=9-4x/3
y=3-4x/3
slope=x= -4/3
y intercept
y=3-4(0)/3
y=3-0
y=3
Answer:
C
Step-by-step explanation:
Since the angles are congruent, that means that they are equal to each other.
this would mean that the binomial, 5x+2, is equal to 32.
5x + 2 = 32.
Now just solve for x.
5x = 30
x = 6.
The Answer here and if u want to solve something from math u can use photo math
Step-by-step explanation:
35 + 3 = 5 x 14
38 = 70
False
Answer:
Regular Pentagon
Step-by-step explanation:
A regular icosahedron is a twenty-faced polyhedron, each face being an equiangular triangle. Each vertex is joined together by 5 faces, therefore the polygon formed at each vertex is a regular pentagon.
We can also figure out the number of faces at each vertex using Euler's formula
F+V=E+2
F=number of faces = 20
E=number of edges = number of triangular faces * edges/triangle /2
(since each edge is shared between two faces)
= 20*3/2
=30
Number of vertices
= E+2-F = 30+2-20 = 12
So number of edges meeting at each vertex
= 30 / (12/2) = 30/6 = 5
(12/2 because each edge joins two vertices).
