Write a function that models each variation. x = 1/3, y = 1/5, and r = 3 when z = 1/2, and z varies directly with x and inversely with the product of r² and y.

Answers

Answer 1

Answer:

z = 2.7x/r²y

Step-by-step explanation:

z = kx/r²y

½ = k × ⅓ ÷ (3² × ⅕)

½ = ⅓k × 5/9

k = 27/10 = 2.7

z = 27x/10r²y

z = 2.7x/r²y

Which statement about solving inequalities is true?Adding the same value to both sides of an inequality does not change the solution set.
Subtracting the same value from both sides of an inequality changes the solution set.
When dividing both sides of an inequality by the same positive value, it is necessary to reverse the inequality sign.
When multiplying both sides of an inequality by the same negative value, it is not necessary to reverse the inequality sign.

Answers

The statement which is true about solving inequalities is; Adding the same value to both sides of an inequality does not change the solution set.

Discussion:

Similar to equations, when solving inequalities; adding or subtracting the same value to both sides of an inequality does not change the solution set of the inequality.

In essence, the statement which is true about solving inequalities is; Adding the same value to bothsides of an inequality does not change the solution set.
