Answer:

gradient= -3

Step-by-step explanation:

Whenever you're calculating a gradient, you use the formula Δy÷Δx so in this case, the change in x will be 1 and the change in y will be -3 as it goes down to meet the line and not up so -3÷1= -3

∴ the gradient(m) = -3

Hope this helps.

Mashcka [7]
<h2>Time taken by Helga to wax the car is 72 minutes</h2>

Step-by-step explanation:

Let w be the work of waxing.

Rosita can wax her car in 2 hours or 120 minutes.

Time taken by Rosita = 120 minutes

\texttt{Rate of Rosita = }\frac{W}{120}

Let time taken by Helga be t,

\texttt{Rate of Helga = }\frac{W}{t}

When she works together with Helga, they can wax the car in 45 minutes.

We have

             \frac{W}{\frac{W}{120}+\frac{W}{t}}=45\\\\120t=45(120+t)\\\\120t=5400+45t\\\\t=72minutes

Time taken by Helga to wax the car is 72 minutes
