Answer:
it's 1/7^2
Step-by-step explanation:
When multiply bases with exponents, as long as they are the like bases, you add the exponents. 7^3 x 7^-5 = 7^-2.
When you have a negative exponent, you can get rid of it by moving it to a fraction. put a 1 over the base and exponent and drop the negative, so 1/7^2
The answer is A because there is a common difference of 3 and that makes it Arithmetric
2 solutions because you have 2 different equations
1/4

Answer:
Step-by-step explanation:
5+ 3(у- 4) = 5(y+2) - у
(expand)
5 + 3y - 12= 5y + 10 -y
(combine like terms)
3y - 7= 4y + 10
(move the variables to one side)
-7 = 4y - 3y + 10
(move numbers to one side)
-7 - 10= 4y - 3y
(simplify)
-17 = y or y = -17
I hope this helps!
