Answer:

√85 or 9.22

Step-by-step explanation:

For this, you'd want to use the distance formula, which is just something you'd eventually memorize.

Distance = $\sqrt{(x_{2}- x_{1})^{2} + (y_{2}- y_{1})^{2}}$

Then, you'd plug in the values. Something to keep in mind is the coordinate that is farther right will be ( $x_{2} ,y_{2}$ ), since $(x_{2}- x_{1})$ is supposed to represent the change in x (and same with the y).

d = √( (7 - (-2))² + (9 - 7)²)

= √( (9²) + 2²)

= √(81 + 4)

= √85

= 9.22

I hope this helps!

Pascal sells fruit from a fruit stand. He starts the day with 80 pounds of fruit. In the morning, 5 customers each buy w pounds

An algebraic expression that represents the weight of the fruit that Pascal still has after feeding the birds is 26.7 - 1.7w.

The total pounds of fruit that Pascal has after feeding the birds can be determined by subtracting the sum of the pounds of fruits he sold and the pounds of fruits he uses to feed the birds from the total pounds of fruit he had at the beginning of the day.

Pounds of fruit left = pounds of fruit he had at the beginning of the day - (pounds of fruit he sold + pounds of fruits he used to feed the birds)

Pounds of fruit he sold = 5 x w = 5w pounds

Pounds of fruits he used to feed the birds = $\frac{2}{3}$ × $(80 - 5w)$ = 53.3 - 3.3w
