In football a team needs 10 yards to make a first down. suppose that in three plays, your team gains 6 yards, then loses 2 yards, then gains 7 yards. what was the total yardage and, did the team make a first down? on a number line

6-2 = 4

4+7 = 11 total yards

 11 is more than 10 so yes they made a first down

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false
