Part A: you have to set up a system of equations for this. You should get m=35. Now you can solve y=mx+b for b and get b=200. So your answer is y=35x+200.

Part B: the slope means that he earns 35 additional dollars per hour.

PLESE HELP ill GIVE BRANILY<br><br> Solve for x. 3.5(7-x)+32=106-1.5(4x+18)
murzikaleks [220]

Answer:

X=9

Step-by-step explanation:

3.5(7−x)+32=106−1.5(4x+18)

Step 1: Simplify both sides of the equation.

3.5(7−x)+32=106−1.5(4x+18)

(3.5)(7)+(3.5)(−x)+32=106+(−1.5)(4x)+(−1.5)(18)(Distribute)

24.5+−3.5x+32=106+−6x+−27

(−3.5x)+(24.5+32)=(−6x)+(106+−27)(Combine Like Terms)

−3.5x+56.5=−6x+79

−3.5x+56.5=−6x+79

Step 2: Add 6x to both sides.

−3.5x+56.5+6x=−6x+79+6x

2.5x+56.5=79

Step 3: Subtract 56.5 from both sides.

2.5x+56.5−56.5=79−56.5

2.5x=22.5

Step 4: Divide both sides by 2.5.

2.5x

2.5

=

22.5

2.5

x=9

igomit [66]

Answer:

The answer to your question is 2 seconds

Step-by-step explanation:

Data

function   y = -14x² + 56x

maximum height = ?

Process

1.- Find the derivative of the function

                y' = -28x + 56

2.- Equal to zero the result

                      -28x + 56 = 0

3.- Solve for x

                      -28x = - 56

                            x = -56/-28

                            x = 2

4.- Conclusion

    It takes to the ball 2 seconds to reach the maximum height.
