Suppose j varies jointly with g and v, and j=2 when g=4 and v=3.
find j when g=8 and v=9.

Step-by-step explanation:

we know that

In a join variation, If j varies jointly with respect to g and v, the equation will be of the form

where k is a constant

step 1

Find the value of k

we have

j=2,g=4,v=3

substitute and solve for k

The equation is equal to

step 2

Find the value of j when g=8,v=9

substitute the values in the equation and solve for j

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
