Answer:

Cost = 112.266 cent/km

Step-by-step explanation:

Given

Unit\ cost = R17.82/litre

Rate = 6.3litre/100km

Required

The fuel cost in cent\ per\ km

This is calculated using:

Cost = Unit\ cost * Rate

Cost = R17.82/litre * 6.3litre/100km

Cost = R17.82 * 6.3/100km

Cost = R1.12266/km

Multiply by 100 to get the cost in cents

Cost = 1.12266 * 100 cent/km

Cost = 112.266 cent/km

Write the slope intercept form of the graph plz
Mama L [17]

Answer:

y = 3x - 6

Step-by-step explanation:

slope intercept form is: y = mx + b

m is your slope, so figure it out by doing rise/run

you rise 3, over one which is 3/1, but simplifies to 3

b is your y-intercept, find it by seeing where the line crosses the y-axis, which is -6

therefore, your answer is: y = 3x - 6

Evaluate \dfrac{3}{2}+(-k)+(-2)
Dimas [21]

As I understand, we need to evaluate the given rational expression, we will get that the evaluated expression is equal to - 1/10

<h3>Evaluating expressions:</h3>

Evaluating an expression just means that we need to replace the variable in the expression for a given value, here we have the expression:

\frac{3}{2} + (-k) + (-2)

And we want to evaluate it in:

k = -\frac{2}{5}

So we just need to replace k by that value in the above expression, we will get:

\frac{3}{2} + (-(-\frac{2}{5} )) + (-2)

Now we can just solve this:

\frac{3}{2} + (-(-\frac{2}{5} )) + (-2)\\\\\frac{3}{2} + \frac{2}{5}  + (-2)\\\\\frac{15}{10} + \frac{4}{10}  + (-2) = \frac{19}{10} - \frac{20}{10}= -\frac{1}{10}
