Can someone help me with these

1.)If K(x) = |x-3|+x, find K (4)

2.)At one college, a study found that the average grade point average decreased linearly according to the function g(h)=2.90-0.10h where h is the number of hours per week spent watching reality shows on television. Compute g(6) and interpret its meaning.

3.)Solve the formula for y. -4x + 9y = 3

4.)Are the two lines parallel, perpendicular, or neither?

14x+2y=2 ; 3y=-21x+5

5.)The temperature, T=55m+70, inside an oven can be described by the equationfor the first ten minutes after it's turned on, where m is minutes. Find the T-intercept, and interpret its meaning in the context of this problem.

6.)Robin's job as a telemarketer pays $6 per hour, plus $0.25 for each person she keeps on the phone for over 2 minutes. Her hourly wage is given by 6, y=6+0.25x, where x is the number of people staying on the phone for over 2 minutes in a one hour span. Find the ordered pair corresponding to x=11 and interpret its meaning in the context of this problem.

7.)The average attendance, A, at a minor league baseball park can be modeled by the equation A=30w+6000where w is the number of games the team won in the previous year. Find the w-intercept. Does it provide any realistic information about this situation?
