B) y=x-4 not sure how to explain it, but because the y intercept is -4, it is almost certain that the last number will ne -4 and since x is equal to 4 y must equal x-4. Might be wrong though ('o')
The dual of a cube is an octahedron, shown here with vertices at the cube face centers. ... Thus, the regular polyhedra – the (convex) Platonic solids and (star) Kepler-Poinsot polyhedra – form dual pairs, where the regular tetrahedron is self-dual.
Answer:
<h2>Q = 32</h2>
Step-by-step explanation:
We will check whether the given pair x = 3 and y = 2 is the solution of the first equation.
4(3) - 5(2) = 12 - 10 = 2 CORRECT
Put x = 3 and y = 2 to the equation 6x + 7y = Q:
Q = 6(3) + 7(2)
Q = 18 + 14
Q = 32
