The value of m in the equation 9m-4=-18+2m
Answers
First, we transfer 2m to the other sideand change operation from positive to negative. We also do the same for -4 andchange operation from negative to positive in order to solve this equation.
9m - 2m =-18 + 4
Next we simplysubtract and add from left to right, respectively.
7m = -14
Then, we can now findm by dividing both sides with 7…
7m/7 =-14/7
We’ve arrived at the answer!
m = -2
Checking:
9(-2) - 4= -18 + 2(-2)
-18 - 4 =-18 - 4
-14 = -14
I hopethis helps. :)
9 * m - 4 = - 18 + 2 * m
9 * m - 2 * m = - 18 + 4
7 * m = - 14 /7
m = - 14 / 7
m = - 2
The correct result would be - 2.

Tetrahedron is a Platonic solids which is also a pyramid, i.e. Option (A).
What is pyramid?
Pyramid is a three dimensional shape. Pyramid is a polyhedron formed by connecting a polygonal base and a point. A triangular pyramid is also called a tetrahedron.
- A tetrahedron is known as a triangular pyramid in geometry. The tetrahedron consists of 4 triangular faces, 6 straight edges, and 4 vertex corners. It is a platonic solid which has a three-dimensional shape with all faces as triangles.
So,
As mentioned in the above definition "A triangular pyramid is also called a tetrahedron."
Hence, we can say that Tetrahedron is a Platonic solids which is also a pyramid, i.e. Option (A).

solve for x
replace x with f inverse
replace y with x
so
first minus 2 both sides
y-2=√(2x-3)
square both sides
y^2-4y+4=2x-3
add 3 to both sides
y^2-4y+7=2x
divide both sides y 2
(y^2-4y+7)/2=x
x turns to f inverse and y turns to x
f(x)⁻¹=
