What would happen if the rock sample pictured above was first
exposed to energy from the Earth's
interior and then millions of years
later energy from the sun?

Explanation: If originally, sedimentary rocks are exposed to energy from the sun, no changes will occur to them. One will hardly spot any difference in their mineralogical composition as such. ... Heat from the interior can reach a staggering 6000°C which is more than enough to cause a metamorphic change in a body rock.

explanation:

6x+4y=16

-6x-9y=-6

-5y=10

y=-2

x=4
