Answer:
C. Or the third option
Step-by-step explanation:
When you multiply something by a power of ten the decimal moves either left or right by the exponent. That probably sounds really confusing but here are some examples. If you multiply a number by 10^4 the decimal will move right 4 places making the number larger. Meanwhile if you multiplied it by 10^-4 it will move to the left 4 places making the number smaller. In your case, when you multiply 1.207 by 10^7, the decimal moves places to the right which makes it 12,070,000

Answer:
a= (y-4x-6)/X
Step-by-step explanation:
Make ax the subject of the formulae
-ax=4x+6-y
Multiply both sides by minus (-)
ax= y-4x-6
Divide both sides by x
a= (y-4x-6)/x
