So the distance formula is $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ . Using this, our equation is $\sqrt{(7-(-8))^2+(-1-(-9))^2}$ and we can solve for it as such:

$\sqrt{(7-(-8))^2+(-1-(-9))^2}\\ \sqrt{15^2+8^2}$

As we see with this radical, the sum that's under it is 15^2 + 8^2, or the third option.

Please help me with this math problem

professor190 [17]

Answer:

Step-by-step explanation:

The inequality is 1.20$ x + 3.60 < 9.60, the amount of money in total that Rammy has. As said, for each pound of peaches it would cost 1 dollar and 20 cents (1.20) So for the gallon of milk if Rammy bought it he would have 6$ left to spend on the pounds of peaches. So you do 6$ (600) divided by 1.20$ (120) and you would get 5 pounds of peaches. Therefore, Rammy can buy 5 or more pounds of peaches.
