answer is D
graduent should be m¹×m²=-1
and should be the inverse of the other
So we have 11400 +11400×x=12711
this represents the original price plus some percentage of the original price is equal to the new price. now all we need to do is solve for x
so 11400+11400x=12711
subtract 11400 from each side
11400x=1311 now divide both sides by 11400
x=.115 or about 12%
we can. check by finding 12% of the original price.
11400×.12=1368
now add to 11400
11400+1368=12768 so we are a bit over. this is because it is actually 11.5% just depends on how accurate your answer needs to be

Answer:
An optical prism is a transparent optical element with flat, polished surfaces that refract light. ... A dispersive prism can be used to break white light up into its constituent spectral colors (the colors of the rainbow).
Step-by-step explanation:
It all depends on the math question but usually you solve for x, then check it. Plug x back in and see if it works. But it all depends on the math problem
