I don't understand what you are asking me to do here. Did you copy it in correctly?
Answer:
Percent of change ill always be in positive number . As when we take a reference point , all the measurements becoke positive.
The given statement "to divide a fraction by another fraction is to multiply the dividend and the multiplicative inverse of the divisor" is true.
Dividing fractions is nothing but multiplying the fractions by reversing one of the two fraction numbers or by writing the reciprocal of one of the fractions. By reciprocal we mean, that if a fraction is given as a/b, then the reciprocal of it will b/a.
To divide a fraction by another fraction is to multiply the dividend and the multiplicative inverse of the divisor is true.
Therefore, the given statement is true.

Answer:
The solution set is {-1, 7}
Step-by-step explanation:
Rewrite x^2-6x=7 as x^2 - 6x = 7.
Identify the coefficient of the x term; it is -6.
Halve this coeff (obtaining -3)
Square this result (obtaining 9)
Add 9 to x^2 - 6x and then subtract 9 from the result: x^2 - 6x + 9 - 9
Then we have:
x^2 - 6x + 9 - 9 = 7. Add 9 to both sides, obtaining
x^2 - 6x + 9 = 16
Rewrite x^2 - 6x + 9 as the square of a binomial: (x - 3)^2
Then we have
(x - 3)^2 = 16
Taking the square root of both sides, we get
x - 3 = ±4, so that: x = 3 + 4 = 7, and x = 3 - 4 = -1.
The solution set is {-1, 7}.
Answer:
To complete the square x^2-6x=7
We take the coefficient of X which is -6
divide it by 2 -3
square that number 9
then add it to both sides of the equation.
x^2 -6x + 9 = 16
(x -3) * (x -3) = 16
We take the square root of both sides:
a) x-3 = 4
b) x-3 = -4
Therefore, x = 7 and x = -1
