Any number raised to power of 0 is 1.
In (-4x)^0, because of the parenthesis, the whole number is being raided to 0, which gives 1.
But in -4x^0, only x is being raised to 0, thus -4x^0 = -4(1) = -4.
Part A: 7/10 because .7 represents 70/100 of a whole, or 7/10.
Part B: I think 1 and 89/100 because 89/100 represents that fraction
These are my answers, so I may be wrong.
Hope I helped, and good luck!
6, 9, 9, 12, 18, 24, 24, 24, 37
37-6= 31
X=6 and y=-9. Not sure if y is correct since I kind of rushed but I hope this helps!
