15 POINTS Which expresses is equivalent to 4^4 x 4^-9
A. 4^13
B. 4^5
C. 1/4^13
D. 1/4^5

D. 1/4^5

Step-by-step explanation:

when you add the two, you get 4^-5. since you cannot take a number to a negative power, you have to change the equation to the inverse which is 1/4^5

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
