Answer:

Step-by-step explanation:

Add combine like terms which are 4k and 3k which =7k-14=21 then add 14 on both sides to its self and to the 21 which = 7k=35 then divide the 7 on both sides which then equals k=5

Answer:

$\frac{ {x}^{2} }{y(x - y)} + \frac{ {y}^{2} }{ - x(x - y)}$

$\frac{ {x}^{2} }{y(x - y)} - \frac{ {y}^{2} }{x(x - y)}$

$\frac{ {x}^{2} \times x - {y}^{2} \times y}{xy(x -y)}$

$\frac{(x - y)( {x}^{2} + xy + {y}^{2}) }{xy(x - y)}$

$\frac{ {x}^{2} + xy + {y}^{2} }{xy}$

<u>Given</u>:

The given graph represents the cost of the Kayak's rental per hour.

The coordinates are (2,30) and (3,45)

We need to determine the unit rate of renting per hour.

<u>Unit rate of renting:</u>

The unit rate of renting can be determined using the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

Substituting the coordinates (2,30) and (3,45), we get;

$m=\frac{45-30}{3-2}$

Simplifying, we get;

$m=\frac{15}{1}$

Dividing, we get;

$m=15$

Thus, the unit rate for renting a Kayak is $15 per hour.
